CHAPTER 1: GETTING STARTED CHAPTER 1: GETTING STARTED This chapter contains an introduction to Escort Memory Systems and includes general information relating to the HS500E Industrial Ethernet Antenna and common uses for RFID technology. 1.1 INTRODUCTION Welcome to the HS500E Industrial Ethernet Antenna - Operator’s Manual. This manual will assist you in the installation, configuration and operation of Escort Memory Systems’ HS500E Industrial Ethernet Antenna. The HS500E Ethernet Antenna is a complete read/write Radio-Frequency Identification solution. It is designed to be reliable and rugged, in order to meet and exceed the requirements of the industrial automation industry. The HS500E Ethernet Antenna provides RFID data collection and control solutions to shop floor, item-level tracking and material handling applications. Escort Memory Systems’ headquarters in Scotts Valley, CA. Company Background Escort Memory Systems has long been an industry leader in providing Radio Frequency Identification (RFID) devices, building a solid reputation by consistently delivering an extended selection of quality, durable industrial RFID systems. RFID Overview The first step in most RFID systems involves attaching a tag to a product or its carrier. The RFID tag acts as an electronic identifier, portable job sheet, or real-time tracking database. Tags are identified, read and written to by issuing specific commands from a Host computer. Tags can be read and written to through any nonconductive, non-metallic material, while moving or standing still, in or out of the direct line of sight.

CHAPTER 2: INTERFACING WITH THE HS500E CHAPTER 2: INTERFACING WITH THE HS500E The HS500E supports four different interface connections over Ethernet. • MODBUS-TCP • ETHERNET-IP • TCP-IP • OnDemand The process of issuing commands and receiving responses depends on the interface chosen and the Host computer that is connected to the HS500E. This chapter contains a brief overview of how commands can be sent using the four different interfaces listed above. For additional information regarding the interface used by your particular RFID application, please refer to the documentation for your Host software program. HS500E – OPERATOR’S MANUAL P/N: 17-1305 REV 01.D (08-05) PAGE 11 OF 51
CHAPTER 2: INTERFACING WITH THE HS500E 2.1 MODBUS-TCP INTERFACE Note: Maximum number of registers transferred to/from an RFID tag per command issued = 125 Registers (250 Bytes). Commands must be placed in the Holding Register Area of Node 1, starting at address 40001. Most commands utilize 6 registers (double-byte values or words). The Write Data command will require more words to transmit the data used for the Write. The first register, 40001, indicates the number of words in the Command Packet (including the Overall Length). The command will trigger a response which will be returned at Node Address 33 (Device ID 33), in registers 40001 and up. Below is an example taken from Modscan32, a utility that implements ModBus on a PC. Input The input area is highlighted in red. When the value of the 40001 register for Node Address 1 transitions from 0 to a non-zero length, the command will be issued by the Host and executed by the HS500E. The resulting response is reported in the output area at Node Address 33 (Device ID 33). HS500E – OPERATOR’S MANUAL P/N: 17-1305 REV 01.D (08-05) PAGE 12 OF 51
CHAPTER 2: INTERFACING WITH THE HS500E When the length is set at 40001, the command is executed and the result returned. 40001: <0006H> When the command is completed, the HS500E will reset the length at 40001 of Node Address 1 back to 0. This way a simple handshaking mechanism can be implemented. HS500E – OPERATOR’S MANUAL P/N: 17-1305 REV 01.D (08-05) PAGE 13 OF 51
CHAPTER 2: INTERFACING WITH THE HS500E 2.2 ETHERNET/IP INTERFACE The mechanism to send commands over Ethernet/IP is similar to that of MODBUS-TCP. Commands must still be copied to the appropriate registers. However, the mechanism for handshaking is different. For example, in a ControlLogix environment, commands must be written to the ControlLogix tags that are generated when the HS500E is added to the I/O Configuration. The first step is to add the HS500E to the ControlLogix PLC. To add the HS500E to the PLC using RSLogix5000, right click on the Ethernet Bridge Device and select “New Module…” Choose Generic Ethernet Module. HS500E – OPERATOR’S MANUAL P/N: 17-1305 REV 01.D (08-05) PAGE 14 OF 51
CHAPTER 2: INTERFACING WITH THE HS500E Assign a name to the new device. In the example below, the device has been named EMS. Configure the IP Address to match the IP Address of the HS500E. Match the Connection Parameters to the image below. After clicking the OK button, there will be predefined tags containing the specified I/O Information. Predefined Tags INPUT EMS:I.Data [0] = Consume Data Sequence Number Handshake EMS:I.Data [1] = Produce Data Sequence Number EMS:I.Data [2] = Node 1 Serial Produce Data Size EMS:I.Data [3-202] = Node 1 Serial Produce Data OUTPUT EMS:O.Data [0] = Produce Data Sequence Number Handshake EMS:O.Data [1] = Consume Data Sequence Number EMS:O.Data [2] = Node 1 Serial Consume Data Size EMS:O.Data [3-202] = Node 1 Serial Consume Data HS500E – OPERATOR’S MANUAL P/N: 17-1305 REV 01.D (08-05) PAGE 15 OF 51
CHAPTER 2: INTERFACING WITH THE HS500E The image below displays the input and output tags during the execution of a command: Commands are placed into the O.Data structure, beginning at word 2, while their corresponding responses can be located in the I.Data structure again beginning at word 2. The data located at words 0 and 1 are used for handshaking. The device that produces the information must increment the sequence number by one for every data packet that is exchanged. The device that consumes the information must echo the sequence number in the handshake location after the data is processed. Valid sequence numbers are 1 to 65535, 0 is not allowed. HS500E – OPERATOR’S MANUAL P/N: 17-1305 REV 01.D (08-05) PAGE 16 OF 51
CHAPTER 2: INTERFACING WITH THE HS500E Below is a sample ladder logic program that sets up a timer to send a new request every 1000ms. Every time a new message is sent, the command (0xF000) and length (0x0006) are written to the I/O Data structure and the Consume Data Sequence Number is incremented by 1. Note that if the Consume Data Sequence Number reverts back to 0, the sequence number must be set to 1 (see rung 2 in the image below). With each scan the PLC copies the Produce Data Sequence Number to the Produce Data Sequence Number Handshake. This process is used to acknowledge the receipt of the data from the HS500E. HS500E – OPERATOR’S MANUAL P/N: 17-1305 REV 01.D (08-05) PAGE 17 OF 51
CHAPTER 2: INTERFACING WITH THE HS500E 2.3 TCP/IP INTERFACE It is also possible to communicate with the HS500E through a standard TCP-IP session. A session between the client software and the reader consists of a connection setup, data transactions and the connection termination. The HS500E acts as the server and the user must supply the client software. All connections to the HS500E are initiated by client software only. If, for example, an existing connection terminates unexpectedly, the HS500E will not attempt to contact the client software to reestablish the connection. The client software is responsible for opening, maintaining, and closing any TCP-IP session. The client software must first establish a TCP socket connection to the Ethernet Antenna on port 50200. After connecting successfully, communication between the client software and the Ethernet Antenna can proceed. When communication with the Ethernet Antenna is no longer necessary, it is the responsibility of the client application to terminate the connection. RFID Commands follow the format below: <Data_Size><Data><Reserved_Fields><Checksum> WHERE: <Data_Size> = data length in number of words. <Data> = words that comprise the command. <Reserved_Fields> = will always be 0x00, 0x00 <Checksum> = 16-bit 2’s compliment of the sum of all bytes HS500E – OPERATOR’S MANUAL P/N: 17-1305 REV 01.D (08-05) PAGE 18 OF 51
CHAPTER 2: INTERFACING WITH THE HS500E Example: The string below is an example of a Read Data command sent to the HS500E: 0x00 0x06 0xAB 0x02 0x00 0x01 0x00 0x32 0x00 0x01 0x00 0x20 0x00 0x00 0xFE 0xF9 Note: the first 12 bytes are listed in the table below; the remaining 4 bytes are reserved fields and checksum.

CHAPTER 2: INTERFACING WITH THE HS500E 2.4 ONDEMAND CONFIGURATION After you have confirmed that the PC, HS500E and PLC can communicate, it is time to use the HS500E’s built-in Web Server to configure the HS500E’s “OnDemand” communications features. OnDemand links the Industrial Antenna to specific “Tags” as defined in the ControlLogix PLC. NOTE: the ControlLogix PLC refers to a “Tag” as a small block of internal memory that is used to temporarily store outgoing (command) and incoming (response) data. Within each tag, information is stored in two-byte segments, known as registers or “words.” OnDemand communications features are accessed through the HS500E’s built-in Web Server. 1. Start by opening a Web browser on the PC. 2. In the URL address field, enter the Industrial Gateway’s IP address: 192.168.0.100 3. Press ENTER. The OnDemand Website will be displayed. To access the HS500E’s OnDemand features, type the HS500E’s IP address into the URL Address field (as depicted above) and then press ENTER. A screen shot of the HS500E’s OnDemand Website – Main Page The Main Page of the OnDemand Website lists the IP address (and several other network parameters) as currently stored on the HS500E. HS500E – OPERATOR’S MANUAL P/N: 17-1305 REV 01.D (08-05) PAGE 21 OF 51
CHAPTER 2: INTERFACING WITH THE HS500E There are three important links on this page. They are labeled: • IP Configuration • OnDemand Configuration • OnDemand Status 2.4.1 IP Configuration The IP Configuration page provides an option to modify and configure the HS500E’s IP address, Subnet Mask and (Network) Gateway Address. To modify the IP settings of the HS500E, go to the HS500E’s OnDemand Website Main Page and click the IP Configuration link to arrive at the page displayed below. The OnDemand Website - IP Configuration Page Enter the new IP configuration values in the fields provided. Click the “Save Settings” button to store the configuration changes to the HS500E’s flash memory. Power will be automatically recycled to the unit at which time the HS500E will reset and implement your IP configuration changes. After the HS500E has completely restarted, you can view the new IP configuration by opening a Web browser and entering the HS500E’s new IP address in the URL field. To return to the OnDemand Website – Main Page, click the link labeled Main Page. HS500E – OPERATOR’S MANUAL P/N: 17-1305 REV 01.D (08-05) PAGE 22 OF 51
CHAPTER 2: INTERFACING WITH THE HS500E 2.4.2 OnDemand Configuration At the OnDemand Website – Main Page, Click the link labeled “OnDemand Configuration.” The OnDemand Configuration page will be displayed. As noted, OnDemand is used to link the HS500E to specific tags defined in the ControlLogix PLC. The OnDemand Configuration page allows you to modify the settings of the HS500E’s Subnet Node. The OnDemand Website – OnDemand Configuration Page Follow the steps below to modify the Node configuration settings for the HS500E: At the OnDemand Configuration page, select Node 01 from the drop-down list. (Note that Node 01 is selected in the image above). Click Submit. The OnDemand Node 01 Configuration Page will be displayed. HS500E – OPERATOR’S MANUAL P/N: 17-1305 REV 01.D (08-05) PAGE 23 OF 51
CHAPTER 2: INTERFACING WITH THE HS500E The OnDemand Node 01 Configuration Page PLC Controller Settings 1. Select a Controller Type from the drop-down menu. (Controller Type specifies the type of PLC that will be communicating with the HS500E). 2. Enter the Controller’s IP address. (Controller IP address is the IP address assigned to the PLC). 3. Enter the Controller’s Slot Number. (Controller Slot Number indicates where in the PLC rack the CPU processor module is installed; normally slot 0 for ControlLogix. HS500E – OPERATOR’S MANUAL P/N: 17-1305 REV 01.D (08-05) PAGE 24 OF 51
CHAPTER 2: INTERFACING WITH THE HS500E Write Settings 4. Specify the number of words (between 1 and 200) for the Max Write Size. (The Max Write Size indicates the maximum number of 2-byte data “words” that the HS500E will write to PLC memory each command-response cycle). 5. Specify a Write Tag Name that is 40 characters or less. (The Write Tag Name refers to the name of the tag in the PLC where the HS500E will write data). 6. Enter values for the Write File Address. (The Write File Address indicates the specific memory location within the tag where the HS500E will write data). 7. Enter a number between 5 and 6000 to indicate the number of ticks for the Write Heartbeat Timeout. One tick equals 10ms. Read Settings 8. Specify the number of words (between 1 and 200) for the Max Read Size. (The Max Read Size is the maximum number of words the Industrial Antenna will attempt to retrieve from PLC memory during a single command-response cycle). 9. Specify a Read Tag Name that is 40 characters or less. (The Read Tag Name is the name assigned to the tag in the PLC where the HS500E will retrieve data from). 10. Enter values for the Read File Address. (The Read File Address is the specific memory location within the tag from which the HS500E will retrieve command directed data). 11. Enter a value between 5 and 6000 to indicate the number of ticks for the Read Poll Rate. One tick equals 10ms. (Read Poll Rate indicates the frequency at which the HS500E will poll tags in PLC memory. Polling is the act of repeatedly querying specific memory locations for the presence of new data). 12. After you have entered the proper information on this page, click the “SAVE SETTINGS” button. Your changes will be stored and the OnDemand Configuration summary page will be displayed.

CHAPTER 2: INTERFACING WITH THE HS500E The OnDemand Website - OnDemand Configuration Summary This page displays a brief configuration summary for the HS500E. 2.4.3 Configuring the PLC Meanwhile, in your PLC program, define two tags using the same read tag name and write tag name specified earlier (i.e. EMS_READ1 and EMS_WRITE1). In most PLC programs, the defined tag must have the capacity to store an integer array equal to the Max Size + 3 words. For example, if you previously specified 200 words for the Max Read, the capacity of the corresponding Read Tag in the PLC must be able to store an array of 203 integers.

CHAPTER 2: INTERFACING WITH THE HS500E 2.5 CHECKING COMMUNICATION STATUS 2.5.1 Checking the OnDemand Status Page After configuring the HS500E’s Node (via OnDemand) and defining the two “tags” in the PLC, your next step is to check the communication status between the HS500E and the PLC. • Back at the OnDemand Website - Main Page, click the link labeled: “OnDemand Status.” The OnDemand Status page will be displayed. This message indicates that the PLC has established a connection with Node 01 on the HS500E. The OnDemand Website – OnDemand Status Page The OnDemand Status page provides limited diagnostic information regarding the connection status between the PLC and the HS500E. Using this page, however, you can verify that a connection between the PLC and HS500E has been established successfully. CAUTION: If the PLC and HS500E do not establish a successful connection (as depicted in the image above) restart the Ethernet/IP server on the PLC. If that does not resolve the issue, try cycling power to the HS500E and verify that the PLC and the 1756-ENBT module are functioning and that Ethernet/IP services are running properly. HS500E – OPERATOR’S MANUAL P/N: 17-1305 REV 01.D (08-05) PAGE 27 OF 51
CHAPTER 2: INTERFACING WITH THE HS500E 2.6 VERIFYING THE EXCHANGE OF DATA VIA RSLOGIX 5000 At this point, communication between the PLC and the HS500E should be properly configured and a connection established. You can verify the exchange of information between the two devices using RSLogix 5000. Start the RSLogix program and (if you have not done so already) define two tags (EMS_READ1 and EMS_WRITE1) using the same settings you specified earlier in the OnDemand Configuration section of this guide. • EMS_READ1 is the name of the tag in which the PLC will place commands intended for HS500E (which is assigned to Node 01). • EMS_WRITE1 is the name of the tag in which the HS500E will place PLC-bound response data generated after the execution of a command. NOTE: in RSLogix, “tag” refers to a small block of internal memory that is used to temporarily store outgoing (command) and incoming (response) data. Within each tag, information is stored in two-byte segments, known as registers or “words.” A screen shot of RSLogix 5000 Most likely, you will not be required to add a new module under the 1756-ENBT entry in RSLogix. Through the use of OnDemand communication, the Industrial Gateway acts as an Ethernet/IP client and the PLC acts as the Ethernet/IP server. The Gateway periodically reads from and writes to portions of the PLC memory directly with no messaging instructions or polling required on the part of the PLC.

CHAPTER 2: INTERFACING WITH THE HS500E EMS_Write1 [0] = (2) the counter is copied here by the HS500E to ACK EMS_Write1 [1] = (3) the HS500E increments this counter to signal a response is available EMS_Write1 [2] = Data Size EMS_Write1 [3-202] = Data OUTPUT (where commands are retrieved by the HS500E) EMS_Read1 [0] = (4) the counter is copied here by PLC to ACK the response EMS_Read1 [1] = (1) PLC increments this counter after copying a command EMS_Read1 [2] = Data Size EMS_Read1 [3-202] = Data INPUT (where responses are written by the HS500E) 2.6.1 Handshaking To ensure that messages to and from an HF-Series Controller are properly delivered and received, a handshaking mechanism has been implemented that uses a pair of dedicated words in the exchange. The first 2 words in each tag are dedicated to handshaking. When new information is generated, the producing device (data producer) increments a counter, and the consuming device (data consumer) copies that same counter value to another memory location to signal that the information has been processed. 2.6.2 Handshaking Example The example below gives a simplified explanation of the handshaking scheme. 1. The PLC copies the command to the Output area and then increments the counter in EMS_READ1 [1] 2. The counter in EMS_READ1 [1] is copied by the HS500E to EMS_WRITE1 [0] which acknowledges that it received of the command. HS500E – OPERATOR’S MANUAL P/N: 17-1305 REV 01.D (08-05) PAGE 29 OF 51
CHAPTER 2: INTERFACING WITH THE HS500E 3. The HS500E places the response in the write area and then increments the counter in EMS_WRITE1 [1] which signals that there is new information for the PLC (the RFID controller’s command response). 4. After the PLC has processed the response information, it copies the counter found in EMS_WRITE1 [1] to the read area in EMS_READ1 [0] which signals (to the HS500E) that the PLC has read the response data.

CHAPTER 2: INTERFACING WITH THE HS500E 5. The HS500E will clear its Write Areas by copying O’s to memory, after which it will be ready to receive another command. HS500E – OPERATOR’S MANUAL P/N: 17-1305 REV 01.D (08-05) PAGE 31 OF 51
CHAPTER 3: RFID COMMANDS CHAPTER 3: RFID COMMANDS 3.1 COMMAND STRUCTURE In general, RFID commands sent to the HS500E adhere to a 6-word (12-byte) packet structure, where each word within the packet is comprised of 2-bytes, a Most Significant Byte (MSB) and a Least Significant Byte (LSB). RFID Command Packet Structure Word # Description 01 Overall Length (the number of words in the Command Packet, including the Overall Length field). 02 Command ID Number (example: 0xAB03 - Write Data Command). See RFID Command Table below. 03 Node ID # (will always be 0x0001 for the HS500E) 04 Timeout Value (indicated in .10 second increments). 05 Start Address (the region of tag memory where the Read/Write operation will begin). 06 Read/Write Length (the number of bytes that are to be Read/Written beginning at the Start Address). Note: Commands 02, 03 and 05 are prefixed with AB, as in AB03 (for Command 03). Commands F0, F1, F3 and F4 are appended with 00, as in F300 (for Command F3). Command F2 is appended with 02, 03 or 05, which designates the type of repetitive command. For example, F202 indicates a Repetitive Read Data command.

CHAPTER 3: RFID COMMANDS 3.2 RFID COMMANDS The first three commands in the table below, Commands (AB) 02, 03 and 05, instruct the HS500E to perform standard RFID operations such as data reads, writes and fills. Commands F0 (00), F1, F3 and F4 are used to retrieve or modify information stored internally within the HS500E Ethernet Antenna. Command F2 is designed to continuously repeat one of the first three commands (Continuous Read, Continuous Write, or Continuous Fill). RFID Commands Table Command ID Command Name Description 0xAB02 Read Data Reads data from contiguous areas of an RFID tag’s memory. 0xAB03 Write Data Writes data to contiguous areas of an RFID tag’s memory. 0xAB05 Fill Tag Fills a specified area of a tag with a single data byte value. 0xF000 Read HS500E InfoRetrieves the software version number from the Ethernet Antenna. 0xF100 Test LEDs / Read HS500E InfoRuns an LED test and retrieves the software version number from the Ethernet Antenna. 0xF2(XX) Start/Stop Repetitive CommandStarts (or stops) the repetitive execution of a command. (Where XX represents Commands 02, 03 or 05 for repeating Read, Write of Fill commands). 0xF300 Write IP AddressWrites new IP address configuration settings to the Ethernet Antenna.* 0xF400 Reset Battery Counter ValueResets the value of a tag’s Battery Counter. * Note: Besides executing Command F3, the HS500E’s IP address configuration settings can also be modified by accessing the unit’s internal Web browser and integrated Web configuration pages (see section “2.4 - OnDemand Configuration”). Through the use of a Web browser, one can directly access the HS500E’s internal configuration parameters and manually modify the IP address settings of the HS500E.

CHAPTER 3: RFID COMMANDS COMMAND 02: READ DATA DESCRIPTION Command 02 instructs the Ethernet Antenna to Read Data from a contiguous area of an RFID tag’s memory. DISCUSSION The Read Data command is used to read a specified number of bytes from contiguous areas of tag memory. This command consists of the Overall Length (OAL), the Command ID Number, a Timeout Value, a Start Address and Read Length. The minimum Read Length is 1 byte. If the Read Length extends beyond the last tag address, an error will occur. The Timeout Value is measured in .10 second increments and can have a minimum value of 1 (0x0001). Note that tag address 0x0000 contains a 1-byte Battery Counter Value. To retrieve this value, the Start Address should be set to 0x0000. EXAMPLE In the example below, the Ethernet Antenna will read 4-bytes from the tag beginning at the address 0x0001. The Timeout value is set for 5 seconds (0x0032 = 50 decimal, 50 x .10 = 5 seconds) for the completion of this command. Command from Host Command 02: Read Data – Command Structure Field Name MSB LSB Word Value Overall Length (in words) 00 06 0006 [0xAB] + Command ID Number AB 02 AB02 MSB = reserved, always 0x00.

Additional responses will increment this counter by one (range: 0x00 to 0x7F). • RF Time – the remaining portion of the Timeout Value after the completion of the command. • RF Retry Counter – the number of RF packets that required re-transmission to successfully complete the given command. • Syntax User Counter – the number of improperly formatted commands. • Total Time – the interval of time required to complete the command and response. • Return Data – contains the data that was requested in the command. If an odd number of bytes are retrieved, the LSB of the final Return Data word will contain 0x00. HS500E – OPERATOR’S MANUAL P/N: 17-1305 REV 01.D (08-05) PAGE 35 OF 51
CHAPTER 3: RFID COMMANDS COMMAND 03: WRITE DATA DESCRIPTION Command 03 instructs the Ethernet Antenna to Write Data to contiguous areas of an RFID tag’s memory. DISCUSSION This command is used to write segments of data to contiguous addresses of tag memory. The Write Data command consists of an Overall Length, the Command ID, a Timeout Value, Start Address and Write Length, and the Data Byte Value(s) to be written to the tag. When an odd number of bytes are to be written, the LSB of the final Data Byte Value word must contain 0x00. • Start Address: 0x0001 = Starts writing to the first accessible byte of tag memory (byte 0x0000 is reserved for the Battery Counter byte). • Write Length: 0x0001 = Shortest possible Write Length. If the Write Length is set to 0, or extends past the last byte address of the tag, the unit will generate an error code. EXAMPLE In this example, the Write Data command will instruct the HS500E to write the specified 8 bytes to the tag beginning at the Start Address of 0x0001. A Timeout value of 5 seconds is set for the completion of this command. Command from Host Command 03: Write Data – Command Structure Field Name MSB LSB Word Value Overall Length 00 0A 000A [0xAB] + Command ID Number AB 03 AB03 MSB = reserved (always 0x00) LSB = Node ID # (always 0x01) 00 01 0001 Timeout 00 32 0032 Start Address 00 01 0001 Write Length 00 08 0008 Data Byte Values (01, 02) 11 22 1122 Data Byte Values (03, 04) 33 44 3344 Data Byte Values (05, 06) 55 66 5566 Data Byte Values (07, 08) 77 88 7788 HS500E – OPERATOR’S MANUAL P/N: 17-1305 REV 01.D (08-05) PAGE 36 OF 51

CHAPTER 3: RFID COMMANDS COMMAND 05: FILL TAG DESCRIPTION Command 05 writes one byte of data across a specified range of tag memory. DISCUSSION This command is used to instruct the HS500E to write a particular data byte value to all specified contiguous areas of tag memory beginning at the Start Address. EXAMPLE In this example, the Ethernet Antenna will write the ASCII character “D” (0x44) to 8-bytes of tag memory starting at address 0x0001. A Timeout Value of 5 seconds is set for the completion of this command.

CHAPTER 3: RFID COMMANDS COMMAND F0: READ HS500E INFORMATION DESCRIPTION Command F0 retrieves the currently installed software version number from the HS500E. DISCUSSION This command queries the Ethernet Antenna’s flash memory and retrieves its software version number. EXAMPLE In this example the software version number (1.0A.8) will be retrieved from the EHS500E. (Note: the “period” between characters is also considered part of the software version number). Timeout Value, Start Address and Read/Write Length are not applicable for this command, default value for each = 0x00, 0x00.

CHAPTER 3: RFID COMMANDS COMMAND F1: TEST LEDS / READ HS500E INFORMATION DESCRIPTION Command F1 tests the HS500E’s LEDs and also retrieves its software version number. DISCUSSION This command causes the Ethernet Antenna’s LEDs to flash a coded diagnostic pattern while also retrieving the installed software version number. EXAMPLE In this example the LEDs on the Ethernet Antenna will be tested and its software version number will be retrieved. Timeout Value, Start Address and Read/Write Length parameters are not applicable.

CHAPTER 3: RFID COMMANDS COMMAND F2: START/STOP REPETITIVE COMMAND DESCRIPTION Command F2 repeatedly issues a specified RFID command. DISCUSSION This command will instruct the Ethernet Antenna to continuously repeat a specified RFID command. Note that not all RFID commands support the ability to be continuously repeated. Only Commands 02, 03 and 05 support continuous repetition. To begin repeating a command, set the Overall Length to a value of 0x0006 or greater. To stop this command, change the Overall Length to 0x0000 and re-issue the command (or cycle power to the unit). EXAMPLE This example will instruct the Ethernet Antenna to repeatedly read 4-bytes of data from address 0x0001 of the tag’s memory. Command from Host Command F2: Repeat Command (Read Data) – Command Structure Field Name MSB LSB Word Value Overall Length 00 06 + number of additional words (Write and Fill Commands only).

CHAPTER 3: RFID COMMANDS COMMAND F3: WRITE IP ADDRESS DESCRIPTION Command F3 writes a new IP Address to the HS500E. DISCUSSION This command is used to assign a new IP Address to the HS500E. Writing an IP Address to the HS500E 1. Run Command F3 as shown below (the R/W LED on the HS500E will blink repeatedly for 15 - 20 seconds). 2. After blinking stops, cycle power to the unit (the R/W LED will again blink for 15 -20 seconds). 3. After the R/W LED has stopped blinking (the second time), configure your Host application (ModBus/TCP or Ethernet/IP) to connect to the new IP address (that was assigned to the HS500E in step 1). EXAMPLE This example sets the IP Address of the HS500E to 192.168.253.115. Command from Host Command F3: Write IP Address – Command Structure Field Name MSB LSB Word ValueOverall Length 00 06 0006 MSB = Command ID (0xF3) LSB = 0x00 for this command.

CHAPTER 3: RFID COMMANDS COMMAND F4: RESET BATTERY COUNTER VALUE DESCRIPTION Command F4 resets the value of a tag’s Battery Counter to zero (0x00). DISCUSSION This command is used to reset the value of the Battery Counter when replacing the batteries in a tag. The Battery Counter stores a one-byte value located at tag address 0x0000. To retrieve the Battery Counter Value, execute Command 02 and note the value stored at address 0x0000 on the tag. Clearing the Battery Counter Value does not add voltage to the battery. Falsifying battery life by clearing the Battery Counter Value may lead to incorrect battery life values. Reading address ZERO on the tag should be performed by only one station in a typical assembly line. A tag should have its batteries replaced after it has accumulated over 15 hours of use. When this value reaches 0x0F, battery life is in a condition of decay and should be replaced. Command from Host Command F4: Reset Battery Counter Value – Command Structure Field Name MSB LSB Word Value Overall Length 00 06 0006 MSB = Command ID (0xF4) LSB = 0x00 for this command. F4 00 F400 MSB = 0x00 LSB = Node ID #: (0x01) 00 01 0001 Timeout Value* 00 00 0000 Start Address* 00 00 0000 Read/Write Length* 00 00 0000 * Not applicable for this command, set values to zero (0x00). This command uses a hard coded Timeout Value of 2 seconds. Response from HS500E There is no response for this command. Reset Battery Counter Error The Reset Battery Counter command may appear to time-out or generate an error. After executing Command F4, the user should read the tag at address 0x0000 to confirm that the value of the Battery Counter was indeed reset to 0x00.

CHAPTER 4: ERROR CODES CHAPTER 4: ERROR CODES The HS500E will generate an error response if it was unable to complete a command. The MSB of the second word (Command Echo word) of the response will contain a 1-byte error code indicating the error that was experienced. BASIC ERROR TYPES There are three basic types of error codes. 1. Component failure or damage that may inhibit module usage. An example of this type of error can be a blown fuse. 2. User syntax command error (0x88). This type of error occurs when the user issues an invalid command or attempts to read/write/fill to areas that are not within the range of the tag memory limits. 3. RF response errors. This type of error can occur if the distance from the tag to the antenna exceeds the RF range. Overall Length Errors 0x89: Overall Length Errors: 1. User sends a command with an overall length value of less than 6 bytes. 2. User miscalculates overall length when executing a Write command (where multiple Data Byte Values are to be written). Length Limits 0x8D: Limits or boundaries concerning a Read/Write/Fill Length field were not satisfied. 0x8F: TAG starting address and length conflict with one another. This can occur if the user decides to read data near the end of the tag and specifies a length that exceeds the remainder of the tag memory. Write Length Limit 0x99: User attempts to write to the tag but does not provide the exact number of bytes specified in the Write Length field. Timeout Fail Code 0x9F: Timeout Value has been exceeded.
