Published by SYMEO GmbH Overview Copyright © Symeo GmbH 2012 Page 6 of 97 SYMEO Local Positioning Radar System ® LPR -1D Product Documentation Overview SYMEO Industrial LPR® is a system for contactless, real-time determination of distances and positions. LPR® 1D is a distance measurement system which is particularly well suited for use in very harsh, industrial environments, in which other systems such as mechanical rotary encoders or lasers cannot function for long periods. The Local Positioning Radar System LPR® 1D consists of equal components, which are configured as (depending on customer‟s application): LPR® Slave Unit or LPR® Group Master Unit Figure 1 – LPR® hardware: Group Master Unit or Slave Unit in the design “Compact Unit” The difference between a LPR® 1D Group Master Unit and a LPR® 1D Slave Unit is only the configuration but not the hardware. A LPR® 1D system consist exactly of one component Group Master Unit. And it consists furthermore of one to four LPR® 1D components Slave Unit, subsequent named slave unit 1, 2, 3, 4. Depending on customer‟s application the LPR® 1D hardware has different interfaces. The unit in the design Compact Unit has IP65 protection.

This hardware is called LPR® design ”Integral Unit” compared to the hardware LPR® 1D design “Compact Unit”. Figure 2 – LPR® Hardware – Special Case: Group Master Unit or Slave Unit with integrated antenna in the design “Integral Unit” The LPR® 1D unit with an integrated antenna is available in a plastic housing. An installation description is delivered separately to this document. This antenna is not approved to be in compliance with part 15 of FCC rules and with RSS-210 of Industry Canada. Usage of these antennas may void the FCC/ IC authorization to operate this equipment. Further information is found in the Appendix. 1.1 Safety Instructions LPR®-1D systems are purely tracking and assistance systems. They therefore do not satisfy special requirements for personal safety, e.g. performance level c. Follow the safety instructions in the operating instructions for the device and the additional documentation! Keep these safety instructions and other documents together with the device. 1.2 Installation All installation, repair and servicing work must be carried out by qualified and trained technicians! Overview Copyright © Symeo GmbH 2012 Page 8 of 97 SYMEO Local Positioning Radar System ® LPR -1D Product Documentation 1.3 Repairs Repairs to the device must be carried out by authorized technicians. Unauthorized opening and incorrect repairs could result in severe danger to the user (danger of electric shock, radiated energy, fire hazard). 1.4 Transport and Storage Use the original packaging or other suitable packaging for returns and whenever the system is to be transported. This ensures protection from crushing, impacts, moisture and electrostatic discharge. During setup and before operation, refer to the instructions for environmental conditions included in the operating instructions for the device. Route the wires in such a way that they do not cause a hazard and are not damaged. When connecting the wires, refer to the corresponding instructions in the operating instructions for the device. Do not drop the device and do not expose it to strong vibrations. 1.5 Power Supply A safety-inspected power cable that satisfies the regulations of the country of use is required for the device. Devices with metal housings must only be connected to a grounded, shock proof socket. The device must not be operated unless the nominal voltage of the device matches the local supply voltage. Check the supply voltage of the device in stationary devices. Connecting and disconnecting wires refer to the instructions in the operating instructions for the device. Do not use any damaged wires (damaged insulation, exposed wires). A faulty wire poses a risk of electric shock or fire hazard. 1.6 Setup and Operation During installation, make sure that no objects or fluids get inside the device (risk of electric shock, short circuit). In emergencies (e. g. if there is damage to the housing, control elements or the mains cable, if fluids or foreign bodies have infiltrated the equipment), switch off the power supply to the device immediately and notify your SYMEO Service. Overview Copyright © Symeo GmbH 2012 Page 9 of 97 SYMEO Local Positioning Radar System ® LPR -1D Product Documentation Protect the contacts of all of the device's sockets and plugs from static electricity. Do not touch the contacts. If it is ever necessary to touch the contacts, take the following precautionary measures: Touch a grounded object or carry a ground strap before touching the contacts. This will divert static charges. Proper operation (in accordance with IEC60950/EN60950) of the device is only assured if the housing and integral covers for mounting slots are fully installed (electric shock, cooling, fire protection, noise suppression). If necessary, refer to the corresponding instructions in the operating instructions for the device. In the case of high outside temperatures and intense, direct solar radiation or other radiant heat, it may be necessary to provide a sun or heat shield. 1.7 System Extensions and Accessories Data links to peripheral devices must be provided with adequate shielding. For LAN cabling, the requirements in accordance with EN 50173 and EN 50174-1/2 apply. Use of either a Category 5 shielded cable for 10/100 Ethernet or Category 5e shielded cable for gigabit Ethernet is a minimum requirement. The specifications of standard ISO/IEC 11801 must be complied with. The warranty shall be voided if you cause defects to the device by installing or exchanging system extensions. 1.8 Additional Instructions regarding Compact Type and Integral Type Units The Compact type LPR® unit must not be opened except for installation. The Compact Unit contains no serviceable components. When opening, ensure that no fluid gets into the housing. When sealing the unit, ensure that the seal is included in the cover and that the Compact Unit is completely closed. Otherwise, moisture can penetrate the unit and damage it. In order to install the Integral type LPR® unit, the hood must be detached from the serviceable components. Refer also to the instructions on installing the Group Master Unit. Please take note of the safety and operating instructions in the operating instructions for the system in which you want to install the component. Overview Copyright © Symeo GmbH 2012 Page 10 of 97 SYMEO Local Positioning Radar System ® LPR -1D Product Documentation 2.1 System Description System architecture SYMEO Industrial LPR® is a system for contactless, real-time determination of distances and positions. LPR® 1D is a distance measurement system which is particularly well suited for use in very harsh, industrial environments, in which other systems such as mechanical rotary encoders or lasers cannot function for long periods. All devices have a unique identifier, via which they are actuated. In order to measure the signal transit time and thus also a corresponding distance, the two devices involved are time-synchronized (with accuracy in the picoseconds range). LPR® units use the same frequency band and the same hardware for communicating as for measuring distance. This means that no external WLAN or cable networks are needed for transmitting measurement values and other reference data. 2.2 Technical Data Overview: Technical Data Power supply 10 - 36 V DC Power consumption max. 8W Housing dimensions 260 x 160 x 91 mm (LxWxH) Weight 2.5 kg Connections Power-Supply: Terminal block Antenna: N-connector Ethernet: Plugged connection Relays (optional): Terminal block Profibus/RS232: Terminal block Antennas Up to 4 independent antennas, N-Connector Hardware interface Serial RS232, TCP/IP (optional), Profibus (optional) 7x dry contacts (optional, rating: max. 60 VDC, max. 2 A) Data interface Data port (Symeo binary protocol), Service port (ASCII protocol) Profibus (optional) User data transfer rate 8 bytes/cycle, up to 800 byte/s Frequency range 5.725 - 5.875 GHz, ISM-band System Description Copyright © Symeo GmbH 2012 Page 11 of 97 SYMEO Local Positioning Radar System ® LPR -1D Product Documentation Transmitted power *1 Output power is adjustable Max. 0.025 W EIRP Measuring distance *2 Max. 1800 m Measurement accuracy *2 Max. ±5 cm Measurement frequency *3 Max. 30 Hz Ambient temperature *4 -40 °C to +75 °C Protection class IP 65 with appropriate cable and connectors Compliance CE mark, part 15 FCC *5, RSS-210 *5 *1 Transmitted power/ field strength can be adjusted to assure that emission limits at the antenna are within legal limits, e.g. 25 mW EIRP in the EU and 50 mV/m at a distance of 3 m in the US and Canada. For FCC /IC authorization the maximum field strength is limited by firmware (FCC labeled units only). *2 Depending on the antenna type, mounting position and environment *3 For FCC/IC authorization a maximum measurement frequency of 10 Hz is allowed (FCC labeled units only). *4 Temperature inside the housing can range from -40 °C to 85 °C. *5 FCC labeled units only. 2.3 System Configuration The LPR® 1D system consists of two, three, four or five LPR® units. Each of these units can be configured either as a Group Master Unit or as a Slave Unit. A system consists of exactly one LPR® unit configured as a Group Master Unit and between one and four LPR® units configured as Slave Units. For pure 1D distance measurement two units are required and are arranged as shown in Figure 3. The distance information is available at both units. LPR 1DX System Slave Unit 1 Data in Allocate a Time Slot for Distance Measurement Group Master Unit Data in Distance Measurement Data out, i.e. PC or PLC Data Transmission (Distances, User data, etc.) Data out, i.e. PC or PLC Figure 3: 1D system System Description Copyright © Symeo GmbH 2012 Page 12 of 97 SYMEO Local Positioning Radar System ® LPR -1D Product Documentation Besides the distance information, smaller volumes of user data can also be passed between the units. These are fed in on the serial port of a unit and output in corresponding manner on the other side. Each unit consists of a basic unit, corresponding antenna cable, antenna, as well as power supply and ports. Further options for arranging LPR® units are described in the section 2.6 "Application Examples". 2.4 System Design Each LPR® 1D unit has parameters to provide an explicit allocation to a system and also to ensure the functionality of a system. These parameters are explained in the following: Parameters may only be set with the commissioning tool Symeo Wizard as described in chapter 5.4. Do not change parameters manually in the configuration files. 2.4.1 Station-ID (SID) Each unit has an explicit Identification Number in one system. If using more than one LPR® 1D systems in your environment same station numbers could be used. BUT: In one system all station numbers are different. A system consists at least of 2 units, at most of 5 units. The first unit has the station number 1 (SID 1), the second unit has the station number 2 (SID 2), etc. Unit 1 (SID 1) is the LPR® Group Master Unit, as a coordinator of the system. Units 2 – 5 (SID 2 – 5) are LPR® Slave Units. A Group Master Unit (SID 1) can only measure with a Slave Unit (SID 2 – SID 5) and vice versa, but NEVER with another Group Master Unit or a Slave Unit with another Slave Unit. But the Group Master Unit (coordinator) can measure with up to 4 Slave Units. Keep in mind: SID 1 Group Master Unit SID 2 Slave Unit 1 SID 3 Slave Unit 2 SID 4 Slave Unit 3 SID 5 Slave Unit 4 There is no difference in the hardware of a Group Master Unit and a Slave Unit. The only difference is the configuration software. The Group Master System Description Copyright © Symeo GmbH 2012 Page 13 of 97 SYMEO Local Positioning Radar System ® LPR -1D Product Documentation Unit organizes the measurements. It allocates time slots to the Slave Units to identify when these units are allowed to start with a measurement. 2.4.2 Group-ID (GID) A system is identified clearly by its group number. All units in one system have the same group number. If there is used a second, a third or more systems in your environment, all additional systems must have a different group number (see Figure 5). 2.4.3 FSK Channel (FSK) The measurement of the round trip of flight (RTOF) happens in a frequency band width of 5,725 to 5,875 GHz. In this band width the LPR® system gets a frequency channel. 30 frequency channels are available. All units in one LPR® systems have the same frequency channel. If there are more LPR® systems in your environment each further LPR® system has another frequency channel (see Figure 5). If you commission the system with the LPR® commissioning tool LPR® 1D Wizard, the frequency channel is linked to a group ID. Therefore it is really important to use different group IDs for different LPR® systems. System Number 1 Group-ID: 1 System Number 2 Group-ID: 2 Station 1 Station 2 Station 1 Station-ID: 1 Station-ID: 2 Station-ID: 1 System Number 3 Group-ID: 3 Station 2 Station-ID: 2 Station 3 Station-ID: 3 Station 4 Station-ID: 4 System Number 4 Group-ID: 4 Station 1 Station 2 Station 1 Station-ID: 1 Station-ID: 2 Station-ID: 1 Station 2 Station-ID: 2 Station 3 Station-ID: 3 Figure 4 – Example of the relation Station-ID and Group-ID System Description Copyright © Symeo GmbH 2012 Page 14 of 97 SYMEO Local Positioning Radar System ® LPR -1D Product Documentation Crane Rail SID: 2 GID: 1 Crane Bridge SID: 1 GID: 1 Radio Path SID: 3 GID: 3 Crane Crab SID: 2 GID: 3 SID: 4 GID: 2 SID: 3 GID: 2 SID: 1 GID: 3 SID: 1 GID: 2 SID: 2 GID: 2 Figure 5 – Example of multiple LPR®-systems in one crane environment 2.5 Mode of Operation of the System The distance is determined by measuring the transit time of radio signals. For this, the Group Master Unit first sends a communication packet to the Slave Unit to start the measurement. The unit that is addressed in this way sends a response sequence and a special, wideband response signal which is ideal for making distance measurements. The Group Master Unit synchronizes itself with this signal and after a precisely known time replies in highly synchronized manner with exactly the same signal. The Slave Unit receives this signal and uses the signal transit time to determine its distance from the Group Master Unit. The distance can be output after the measurement by any of the units participating. As an option, if the distance falls below a given value, a switch (dry contact) can be actuated to trigger a warning signal, for example. Besides distance measurement, the system's communication can be used for transmitting user data in the intervals between measurements. Transmission is asynchronous, i.e. the data is requested and transmitted when the measurement has been completed. To transmit data over the system, first a send data request is sent by the LPR® unit to the user. Then the user data is received and transmitted to the second LPR® unit. The data channel has a channel capacity of 8 byte/measurement cycle. This means, the overall capacity depends on the chosen measurement frequency. I.e. if a measurement frequency of 10 Hz is chosen, the capacity is 80 byte/s 2.6 Application Examples Figure 3 shows the simplest arrangement of LPR® units (LPR® 1DX). This is used for measuring the distance between two LPR® units. The abbreviation 1DX means distance measurement without positioning. Some more complex arrangements are illustrated in the following description. 2.6.1 Redundant arrangement (2 x LPR-1DX) For reasons of operational safety, it may be necessary to combine two systems in a redundant arrangement. Figure 4 shows two Slave Units and two Group Master Units installed in a redundant arrangement on two crane bridges. Each Slave Unit communicates System Description Copyright © Symeo GmbH 2012 Page 15 of 97 SYMEO Local Positioning Radar System ® LPR -1D Product Documentation with the opposite Group Master Unit. Both systems measure independently from each other. After the measurement, the distance from the respective partner can be output at each of the participating units. Optionally, a switching contact may also be actuated depending on the distance, e.g., to trigger a warning signal for example if the crane bridges come too close to one another and there is a danger that they may collide. If more than one LPR® system is used, each system has its own group ID and its own frequency channel. So both systems do not disturb each other. 2 x LPR 1DX (Plan View) Crane Bridge 1 LPR Slave unit Antenna Radio Path LPR Group Master unit Crane Bridge 2 Figure 6: LPR® 1DX Redundant arrangement System Description Copyright © Symeo GmbH 2012 Page 16 of 97 SYMEO Local Positioning Radar System ® LPR -1D Product Documentation 2.6.2 Positioning of Crane Crab (LPR® 1DP2) In order to determine positions in two dimensions (x-y coordinates), three LPR® units can be arranged in an L-shape (see Figure 7). In this case, the unit that is configured as the Group Master Unit (unit 1) is equipped with 2 antennas. This unit measures against the first Slave Unit (unit 2) with the first antenna, and against the second Slave Unit (unit 3) with the other antenna, for example. In this way, the position of a crane crab can be determined.

In the arrangement shown in Figure 8, the Group Master Unit (unit 1) is equipped with two antennas. A Slave Unit (unit 2 and unit 3) is installed on each of the two cranes. The two antennas are mounted at the wall at the same height as the respective Slave Units installed on the cranes. In this way, the distance of both cranes from the wall can be calculated.

Therefore it is important to avoid ingress of moisture, dust or any particles into the housing during the installation process. Make sure that there is enough room for the connectors, and particularly that the antenna cable is accessible; pay attention to the permitted bending radius (center of radius to cable core) for standard cables of 10,5cm (for multiple bending under mechanical load) and 4cm (unloaded and static bending). The Compact Unit should preferably be installed so that the connecting sockets point downwards. In this way, the connections are protected from rain and dust. Installation Copyright © Symeo GmbH 2012 Page 37 of 97 SYMEO Local Positioning Radar System ® LPR -1D Product Documentation 4.1.2 Installation To install the Compact Unit, you require 4 round head M6 x 30 screws (at least). Check the position of the unit on the device on which the Compact Unit is to be installed (e.g. a crane bridge). Bear in mind the installation instructions listed above. Drill holes in the device on which the Compact Unit is to be installed. Drill-hole distances: 11 cm wide, 24 cm high (see Figure 10). Open the Compact Unit: With a Phillips screwdriver (Size 0), loosen the top four screws of the Compact Unit lid. Screw the Compact Unit tightly to the device. The installation holes shown in Figure 10 are provided for this purpose. Check that the unit is mounted securely. Close the unit: Place the cover of the Compact Unit on top and fasten the cover with the four screws. Make sure that the cover is securely attached to the housing. Commission the Compact Unit (see chapter 5) 4.2 Installation of LPR® Antennas 4.2.1 Connecting and Wiring up the Antenna and Cable Connect the antennas to the antenna port at the LPR® unit. When using several antennas, ensure that they are connected to the correct ports. Group Master Slave Unit 1 Measured Antenna Antenna Distance 1 Port 1 Port 1 Measured Distance 2 (optional) Measured Distance 3 (optional) Measured Distance 4 (optional) Antenna Port 2 Antenna Port 3 Antenna Port 4 Slave Unit 2 Slave Unit 3 Slave Unit 4 Antenna Port 1 Antenna Port 1 Antenna Port 1 When installing the cable, ensure that electrostatic charging does not occur. Make sure that the cable is not kinked or trapped during installation. The minimum bending radius must always be maintained. With the standard antenna cables delivered, the minimum bending radius (center of radius to cable core) for standard cables is Installation Copyright © Symeo GmbH 2012 Page 38 of 97 SYMEO Local Positioning Radar System ® LPR -1D Product Documentation 10,5 cm (for multiple bending under mechanical load) and 4 cm (unloaded and static bending). The cable must not be attached in a way that squeezes its cross-section. On demand, cables with different flexibility characteristics are available. The antenna plug must not be removed (e.g. for installation purposes) or repaired because the specified electrical properties can only be achieved with mechanical installation assistance. When installing the antenna cable, ensure that the screw connection is seated properly and not tilt. The antenna cable plugs should be finger-tightened before tightening with an appropriate tool to no more than 1.3 Nm tightening torque. 4.2.2 Installing the Antenna(s) The line of sight between the antennas on each unit must not be obstructed. Therefore, when installing the antenna fixture, ensure that no components are blocking the line of sight between the antennas. If necessary, contact the SYMEO technical department. Depending on the antenna type used, offsetting the corresponding antennas (either vertically or horizontally) may degrade the signal strength to the point that communication is lost. Accordingly, corresponding antenna pairs should be installed with as little offset with respect to each other as possible, and preferably none. If necessary, contact the SYMEO technical department. If you change the position of one antenna, this will affect the measurement data. For installation of the planar antennas, it is important to keep the same orientation of polarization for corresponding antennas (see Figure 25). Figure 25: Backside of 23 dBi planar antenna Install the antenna bracket according to the accompanying operating instructions. Secure the antenna in the bracket. Connect the antenna to the antenna cable. Installation Copyright © Symeo GmbH 2012 Page 39 of 97 SYMEO Local Positioning Radar System ® LPR -1D Product Documentation 4.2.3 Fresnel zone The area for radio transmission between two antennas is called Fresnel zone. The main part of energy is concentrated in the first Fresnel zone. This area has to be free of any obstacles otherwise the signal is interrupted or attenuated. The first Fresnel zone can be calculated as follows: is the wave length and the distance between the two antennas. For a frequency of 5.8 GHz a wave length of approx. 0.05 m is calculated. The maximum radius between the two antennas is indicated with . For different distances the maximum radius is given in Figure 26 distance d radius b 10 m 0.36 m 50 m 0.80 m 100 m 1.14 m 250 m 1. 80 m 500 m 2.54 m 1000 m 3.60 m Fresnel zone Antenna 1 Antenna 2 Figure 26 Calculation and figure of Fresnel zone 4.2.4 Installation of Planar Antennas Each antenna type has its own opening angle. To communicate with the opposite antenna the relative antennas has to be located in the opening angles of the opposite antennas. Antennas have to be mounted without any offset (no difference in height and no offset sideways). Make sure that the opening angle is symmetric to the relative direction of motion (compare picture 1 vs. picture 2 in Figure 27). If an offset is not inevitable the antennas have to be tilted (compare picture 3 vs. picture 4 in Figure 27). Notice: If the distance goes below a fixed distance it is possible that no measurements take place any longer in this configuration.

The unit has been connected to the power supply. Antenna(s) and antenna cables for the unit have been installed. Data link has been established via TCP/IP or RS232. Once these prerequisites have been fulfilled you can connect the unit either serially to a PC or as an option (TCP/IP option) to the network and commission the LPR® 1D system. How to do this is explained in the following chapter. 5.1.1 General Commissioning is carried out via the serial service port or the TCP/IP port depending on the LPR® unit model you have: Model with TCP/IP data interface: Configuration via TCP/IP Models with Profibus or RS232 data interface: Configuration via service port C5 or C4 Commissioning Copyright © Symeo GmbH 2012 Page 41 of 97 SYMEO Local Positioning Radar System ® LPR -1D Product Documentation LPR Unit Profibus, RS232 or TCP/IP Data Port RS232 or TCP/IP Service Port PC, PLC etc. Service PC Figure 28: LPR® Unit with Interfaces for Parameterization at Service Port and Distance Data Protocol (Binary data) at Data Port In one LPR® system all distance data (binary data/ protocol) are available at each unit. Also if you have several units in one system (crane bridge, crane crab, wall) you get the binary distance data at each LPR® unit at the data port in this system. 5.2 Connection to LPR® Unit with TCP/IP Interface With delivery the LPR® units have the fixed IP-Address 192.168.1.99, if no other IP-Address is labeled outside the LPR® unit. You can change the IP-address of the LPR® Unit via the web interface of the LPR® Unit as described in chapter 6. To get a connection between your PC and the LPR® unit it is maybe necessary to change the network parameters of your computer. Both units must be located in the same network. That means in this example that the first three numeric pads of both IP-addresses must be the same. Disconnect your PC from the network. Connect the LPR® unit and the computer with a network cable. Open your network settings of your computer. Commissioning Copyright © Symeo GmbH 2012 Page 42 of 97 SYMEO Local Positioning Radar System ® LPR -1D Product Documentation Enter the following fixed IPAddress i.e. 192.168.1.1.

Furthermore it is only allowed to send data to a LPR® 1D unit after the LPR® 1D unit has sent a send request (type 0x02). Table 1 shows an overview which data packets can be applied in which direction. direction Data Type from LPR® 1D to LPR® 1D 0x00 Distance Data 0x01 User Data 0x02 Send Request 0x03 Relay Switching Command Tab. 1: direction of data Sending data to the LPR® 1D unit is only possible after receiving a send request (Type 0x02). The send request type guarantees the “ready-to-receive” status of the LPR® 1D unit. The LPR® 1D can only handle one data packet from one user. If nevertheless data is sent to the LPR® 1D unit without a previous send request, it can result in a reboot of the LPR® 1D unit. Per one send request the user can send only one data set to the LPR® 1D unit. 7.1.2 Structure of Data Packet To apply the protocol on a RS232 interface each data packet starts and ends with a reserved symbol. This reserved symbol cannot appear in the data stream. Figure 58 shows the general structure of the data packet. START 0x7e TYPE 1 byte 1 byte DATA CRC END 0x7f 2 byte 1 byte Figure 58: Structure of data packet Protocol Description Binary XP (1D messages) Copyright © Symeo GmbH 2012 Page 76 of 97 SYMEO Local Positioning Radar System ® LPR -1D Product Documentation The START and the STOP-field is in each data packet the reserved symbol 0x7e and 0x7f. TYPE indicates the type of the data packet. There can be defined up to 256 different types. The TYPE-field is following the DATA-field. The DATA field contains the real data of the packet of the type TYPE. The CRC-field contains a check sum. The check sum is applied to all previous data fields except the START data field. All multi byte integers (e.g. CRC field) are encoded in Network-Byte-Order (Big Endian). All signed integers are encoded in two's complement representation. 7.1.3 Byte Stuffing The two symbols 0x7E and 0x7F are unique for START and STOP-fields. If those symbols occurs within any other field (TYPE, DATA or CRC), they must be replaced by the following order: original symbol replaced by 0x7D 0x7D 0x5D 0x7E 0x7D 0x5E 0x7F 0x7D 0x5F This byte stuffing scheme ensures that the receiver of the protocol can identify definitely the START-field within a flow of data, even if the symbol of the start field occurs within the DATA-field. Example: If the symbol 0x7d is read, it must be cancelled. The following symbol must be XOR combined with 0x20 to recreate the original symbol. Remark: Byte stuffing is deactivated for the fixed frame protocol (compare chapter 7.3). 7.1.4 CRC The CRC-16-IBM with polynomial x16+x15+x2+1 is used for the checksum CRC. The CRC is calculated over all data fields (TYPE and DATA), but not for the START and END field. The CRC-calculation is only applied to the original symbols. The appropriate calculation for coding must applied before byte stuffing. If receiving the data from the LPR® 1D system the byte stuffing must be reserved to get the original symbol. Then the CRC is updated with the original symbol.

A distance data set (or also 2 distance data sets) alternate with a send request. The Send Request indicates that the LPR® unit is listening to a data set from the user (for example relays external commands). The Distance Data sends the data to the user (i.e. to a PLC or to a PC/software).

No acknowledgment of the relay switch command will be sent because this data frame can be ® forwarded to other LPR 1D units and thus no reception on the destination unit is guaranteed. In case ® of faulty data frame (e.g. invalid relays chosen or unknown destination address) the LPR 1D unit will print an error message. Protocol Description Binary XP (1D messages) Copyright © Symeo GmbH 2012 Page 80 of 97 SYMEO Local Positioning Radar System ® LPR -1D Product Documentation 7.3 TCP/IP option: Fixed Frame Protocol If the LPR® unit has a TCP/IP interface two options are available for the protocol. Either you use the protocol as it is sent from the serial interface (with different data type lengths, byte stuffing) or you use a fixed frame protocol. In the first case the data symbols 0x7e und 0x7f (which are reserved for the START and END field) are replaced (see chapter 7.1.3). Byte stuffing causes a different protocol length. For the fixed frame protocol each LPR® data packet is filled up with zero bytes to a fixed length of bytes (i.e. 87 bytes) before the data packet is sent. Byte stuffing does not occur. The START and the END byte are still used but not clear anymore due to not applying byte stuffing. The fixed length of the data packets can be set on the web-interface of the LPR® unit. For the fixed frame protocol the data packets which are sent to a LPR® unit has to be filled up to a fixed length (i.e. 15 bytes). The START- and the END byte have to be occurred as well and byte stuffing does not occur anymore. It is recommended to fill up the data packet with zero bytes to facilitate a troubleshooting. If TCP/IP is used the transmitted data have already a checksum. Therefore the checksum in the protocol is not as important as for the serial interface. Two options for the fixed frame are allowed by the protocol inverter for receiving data in a fixed frame. Either 0x0000 is sent as the check sum to the LPR® unit. Then the protocol inverter is calculating the check sum itself. Or another value (differing to 0x0000) is sent as the check sum. Then this check sum is assumed to be the correct check sum. Otherwise the data packet is rejected. 7.3.1 Detailed description TCP Fixed-Frame Protocol If a TCP fixed-frame protocol is used, a working TCP connection between the PC and the LPR® unit has to be guaranteed. Depending on the configuration of the LPR® protocol inverter either the connection to a port on the LPR® unit has to be initialized from the PC or the LPR® unit is establishing a connection to a PC. If the connection is established, the PC has to read the data from the LPR® unit in fixed data length (i.e. 87 bytes). The first byte is always the START-byte and the second byte is always the TYPE-byte. The relevance of the following data is depending on the data type. Because no byte stuffing occurs the content for a special data type is always constant. For example the measured velocity of the distance data (type 0x00) is always written in the 12.-15 data byte. Sending data from the PC to LPR® unit, a fixed data length has to be chosen (i.e. 15 byte). The first byte (START byte: 0x7e) follow the TYPE-byte. The following data depends on the chosen type, following by the CRC (correct CRC or 0x0000), following by the STOP byte (0x7f). The data packed has to be filled up with zeros. 7.3.2 Detailed description UDP Fixed-Frame Protocol If a UDP fixed frame protocol is used, the IP and the UDP port of the PC has to be configured in the LPR® protocol inverter. The converter sends each data packet as a UDP packet of a fixed length (87 byte) to the PC. Compared to the TCP fixed frame option the UDP fixed frame does not verify if the data packed arrived. The content is the same as for the TCP fixed frame protocol. Protocol Description Binary XP (1D messages) Copyright © Symeo GmbH 2012 Page 81 of 97 SYMEO Local Positioning Radar System ® LPR -1D Product Documentation If data is sent to the LPR® unit the data has to be packed in a fixed data length (i.e. 15 bytes as for TCP fixed frame option). This data packet is sent as UDP packet to the LPR® unit. The port number of the receiver is the same as for the PC. In general bidirectional data communication is not recommended for UDP due to loosing singular data packets. 7.4 Remarks 7.4.1 LPR® 1D Address LPR® 1D unit addresses are completely defined by a 16 bit value: 15 11 10 station ID group ID BB Indicates, if the LPR® 1D unit is defined as a Slave Unit or BB – Slave Unit Bit: as a Group Master Unit (1=Slave Unit, 0=Group Master Unit) group ID: group ID of the unit (1..1022) station ID: station ID of the unit (0..30) In multi cell applications, group ID is the cell ID of the cell. 7.4.2 Distance Error codes The distance data contains an error field which indicates the status of the distance measurement. The following errors can occur: Value Content Source Description 0x00 no error 0x01 no peak detected Slave Unit No measurement signal 0x02 peak too low Slave Unit Measurement signal is imprecise 0x03 nothing received Group Master Unit No measurement data received 0x04 implausible speed Slave Unit Velocity is to high 0x05 measurement botched Slave Unit Measurement is not feasible. 0x06 no occupying received Group Master Unit 0x07 no results received Group Master Unit 0x08 trigger Group Master Unit Measurement valid Measurement channel is not reserved No measurement data received Unit did not attend the measurement Protocol Description Binary XP (1D messages) Copyright © Symeo GmbH 2012 Page 82 of 97 SYMEO Local Positioning Radar System ® LPR -1D Product Documentation Protocol Description for PROFIBUS Interface 8.1 Profibus data structure The total length of one data set is 48 bytes.

For debugging circumstances it might be helpful to install a terminal program to analyze the system. 9.1 Programs 9.1.1 Terminal Program A terminal program is useful for analyzing the system. The recommended terminal program is RealTerm. It is Open Source Software and can be downloaded from the webpage http://sourceforge.net/projects/realterm. Install the program on your PC. 9.1.2 Command Window (only for LPR unit with TCP/IP interface) The easiest way to check a connection between a LPR unit with TCP/IP interface and your PC/network is the command window. The command window is preinstalled in the operating system Windows. Click on the window button Start Run… Enter cmd and click on OK. 9.1.3 Telnet (only for LPR unit with TCP/IP interface) A short way to check the functionality of the LPR unit with TCP/IP interface is Telnet. Telnet is preinstalled in the operating system Windows. Click on the window button Start Run… Enter telnet IP-address Port and click on OK. E.g. enter telnet 192.168.1.99 3045 to open the service port of the LPR unit with IP-address 192.168.1.99 and the port 3045. 9.1.4 Browser (only for LPR unit with TCP/IP interface) A web browser is necessary to make all settings of the LPR unit with TCP/IP interface. You can make network settings as well as settings for the protocol. 9.1.5 Network Scanner (only for LPR unit with TCP/IP interface) A network scanner like the program SoftPerfect (http://www.softperfect.com/products/networkscanner/) is useful for analyzing your network. 9.2 Hardware The following additional hardware is useful: Serial Cable (1:1) less than 2 meters (for a LPR unit without TCP/IP interface ) LAN-cable (for a LPR unit with TCP/IP interface) USB -RS232 converter (if there is no RS232 serial port available at your computer) 9.3 Connection to LPR units with RS232 or Profibus interface If you have a station without TCP/IP interface connect your PC via the RS232 interface to the LPR 1D unit. For this connection you need a RS232 cable (1:1) which should be less than 2 meters long. A longer cable cannot guarantee a trouble-free transmission of data between the LPR unit and the PC. For configuration of the LPR-1D unit the service port (C4) or (C5) is provided (RS232). Trouble Shooting Copyright © Symeo GmbH 2011 Page 85 of 97 SYMEO Local Positioning Radar System ® LPR -1D Product Documentation For connecting to the D-sub socket (C4) please use a standard RS232 cable (1:1) with a maximum length of 2 meters. Optional the RS232 connection can be established via the terminal block (C5). The pin assignment is shown in Figure 60. The configuration of the LPR-1D unit is described in chapter 5 Commissioning. The data port with binary protocol output for units without TCP/IP interface is available on Dsub socket (C8) please use a standard RS232 cable (1:1) with a maximum length of 2 meters or optional the RS232 connection can be established via the terminal block (C7). The pin assignment is shown in Figure 60. If you want to use a longer serial cable for the data port you have to reduce the baud rate of the LPR unit, as described in chapter 5. Typical values for the data rate for different length of the serial cables are: Max. baud Max. Length of RS232 rate cable 19.200 15 m 57.600 5m 115.200 <2 m C7 GND TX RX C8 Figure 60 Internal serial service port C4/C5 and data port C8/C7 (RS232) Using the internal serial interface it is important to avoid moisture, dust or any particles into the housing during the process. If you use a USB-RS232 converter make sure that all necessary drivers are installed for this hardware. Trouble Shooting Copyright © Symeo GmbH 2011 Page 86 of 97 SYMEO Local Positioning Radar System ® LPR -1D Product Documentation 9.3.1 RealTerm (for service port) With a terminal program like RealTerm you can perform more detailed analyzing of the system. Restart the LPR-1D unit before using a terminal program (power off-on) Open now the program RealTerm. In two tabs you have to change the settings: Tab Display: - Choose Display As Ansi - Extend the Rows from 16 to 30 Tab Port: - Change the Baud to 115.200 - Choose the right COM port - Click On Open Depending if you are connected to a Group Master unit or a Slave unit characters appear in the window. If you are connected to a Group Master unit a lot of “t” characters appear in case of a failure. This happens because the Group Master unit tries to make a measurement, but output a failure because the opposite station is not available or connected. “t” means failure of measurement. A working system should output “m” characters. “m” means a working measurement. If you are connected to a Slave unit only “m” characters are shown for a working system. In case of a failure nothing is shown when connected to a Slave unit. 9.4 Connection to the LPR unit with TCP/IP interface If you have a station with TCP/IP interface you only can connect your PC via the TCP/IP interface to the LPR unit. For the connection you need an Ethernet cable. Trouble Shooting Copyright © Symeo GmbH 2011 Page 87 of 97 SYMEO Local Positioning Radar System ® LPR -1D Product Documentation The IP-address is set to the fixed IP address 192.168.1.99 when delivering the system to the customer. To get access to the station you need to set your PC in the network as the LPR unit. 9.4.1 LAN Settings of your PC First you need to disconnect your PC from your network to avoid trouble when changing the IP address of your computer. Now you connect the LPR unit via an Ethernet cable with your PC. If you are not in the same net as the LPR unit you have to change temporary the network settings of your PC. Both IP-addresses must be in the same network, i.e. the first three fields of the IP-address must match. Open your network connection and set a fixed IP address to your computer, i.e. 192.168.1.1. The subnet mask should be set to 255.255.255.0. Click in both windows “OK”. If your firewall is enabled and set to restrictive, it might happen that you cannot access the LPR unit. In this case disable the firewall settings temporary in the tab Advanced in the window Network properties. 9.4.2 Check TCP/IP connection The first way to check the IP-connection from your computer to the LPR unit is to “ping” the LPR unit. Open the command window (Window button Start Run Enter cmd and click on OK). Enter in the window 192.168.1.99 –t and click Enter. Trouble Shooting Copyright © Symeo GmbH 2011 Page 88 of 97 SYMEO Local Positioning Radar System ® LPR -1D Product Documentation You should get a reply from the LPR unit with the fixed IP-address 192.168.1.99 If the connection failed probably your firewall settings of your PC are set to restrictive or the IP-address of the LPR unit is probably not 192.168.1.99. Please check the settings. Compare also the hint in chapter 9.4.1. If you have changed the IP address without bearing in mind the IP address the IP-address could be detected with the program NetworkScanner. 9.4.3 RealTerm (for service port) With a terminal program like RealTerm you can perform more detailed analyzing of the system. Restart the LPR-1D unit before using a terminal program (power off-on) Open now the program RealTerm. In two tabs you have to change the settings: Tab Display: - Choose Display As Ansi - Extend the Rows from 16 to 30 Trouble Shooting Copyright © Symeo GmbH 2011 Page 89 of 97 SYMEO Local Positioning Radar System ® LPR -1D Product Documentation Tab Port: - Enter the IP-address of the LPR unit and the port: IP-address:port - I.e.: 192.168.1.99:3045 - Click on WinSock is RAW - Open the connection Depending if you are connected to a Group Master unit or a Slave unit characters appear in the window. If you are connected to a Group Master unit a lot of “t” characters appear in case of a failure. This happens because the Group Master unit tries to make a measurement, but outputs a failure because the opposite station is not available/ connected. “t” means failure of measurement. A working system should output “m” characters. “m” means a working measurement. If you are connected to a Slave unit only “m” characters are shown for a working system. In case of a failure nothing is shown when connected to a Slave unit. If you do not get access to the LPR unit check if the port is open. The port for the service port is 3045 per default. But it might be possible that you have changed it or did not open it (see chapter 9.4.4). 9.4.4 Web Interface If you can “ping” the IP-address of the LPR unit but do not get data (either via the service port or the data port or both ports) you have to check the settings on the web page of the LPR unit. Open a web browser and enter the IP-address of the LPR unit (i.e. http://192.168.1.99). You get access to the LPR unit. If you are connected via HTTPS-connection, it might appear to dialogue boxes which you have to confirm with “OK”. You see the Start-page of the LPR unit. Trouble Shooting Copyright © Symeo GmbH 2011 Page 90 of 97 SYMEO Local Positioning Radar System ® LPR -1D Product Documentation Click on Settings. You have to authorize yourself. Enter the username „symeo“ and the password and click „OK“. The password is per default „54all2u“. The Settings page of the Web-interface of the LPR unit looks like the following. Scroll down to the section: Serial-to-Ethernet: Here you enter the connection type for the service port (ttyAM1) and the data port (ttyAM2). Both ports should be not disabled. Choose the right connection type and enter the data port. The data port is per default 3045 for the service port and 3046 for the data port. If you have made changes click on “Upload changes” and then on “Reboot system”. After the reboot try again to get access to the LPR unit as described in chapter 9.4.3. Trouble Shooting Copyright © Symeo GmbH 2011 Page 91 of 97 SYMEO Local Positioning Radar System ® LPR -1D Product Documentation 9.5 No Measurements With the configuration tool Symeo Wizard you can check the functionality of your system when connected to the service port as described in chapter 5. If this is working you also can check the data port output for LPR-1D units with TCP/IP or RS232 interface using RealTerm to display. For LPR-1D units with TCP/IP or RS232 interface the data port provides the binary protocol as described in chapter 7. Check List: 1) The antennas are connected to the right port of the LPR 1D unit. measurement 1 measurement 2 (optional) Group Master unit Antenna at Port 1 Slave unit 1 Antenna at Port 1 Antenna at Port 2 Slave unit 2 Antenna at Port 2) If you use planar antennas the orientation of the antenna must be correct. A small label on the backside of the antenna indicates the horizontal and vertical alignment. 3) For a distance measurement always two stations are involved. It has to be a Group Master unit and a Slave unit. Make sure that never two Slave units or two Group Master units are measuring with each other. 4) Units are powered with correct voltage and the LEDs on the front of the units lighting as described in chapter 3 5) Check if the rotary switch S2 is set correctly: position „0“: RS232 position „3“:TCP/IP position „6“: Profibus 6) For LPR-1D units with TCP/IP interface all settings have been made in the WEB server according to chapter 6.2. 7) Units are properly configured with Symeo Wizard as described in chapter 5. 8) Distance data are displayed in Symeo Wizard, see chapter 5.4.2. If not try to overwrite the configuration with the program LPR 1D wizard for all stations again. 9) Check the data port is working. Open the program RealTerm. If connected to a LPR unit with TCP/IP interface open the data port 3046: Enter 192.168.1.99:3046. The display in RealTerm should be set to Hex[space] to “see” binary data. If you use a LPR unit with RS232 interface connect the serial cable to the data port C8, see Figure 60. An example of the binary protocol output at the data port is shown below.
