Features: Replaces the mechanical key Different authorisations Authorisations are identified via printed "Key Mode". Operating Manual PIT m2.1p DMG 1003182EN02 Safety Safety 3.1 Intended use The operating mode selector switch is suitable for machines that can be operated in mul tiple operating modes with different protective measures and/or work procedures. It enables you to switch between defined operating modes, such as: Setup mode Manual mode Automatic mode Service The operating mode selector switch meets the following safety requirements: Interlock to protect against unauthorised switching Contact with a transponder key is required in order to switch to an operating mode. Access authorisations are restricted to certain groups A transponder key with the relevant authorisation is required in order to switch to a cer tain operating mode. Prevents unintentional switching The switch to a different operating mode is only recognised once the corresponding (selection) pushbutton has been operated for a defined period ("deliberate operator ac tion"). Multiple operation of (selection) pushbuttons is detected. Safe "1 from n" circuit of the operating mode outputs The operating mode selector switch only ever leads to one operating mode output "1" signal. A Smart key® must be used as the transponder key. Depending on the application area and its respective regulations, the operating mode se lector switch can be used up to SIL CL 2 (EN IEC 62061) and up to PL d (EN ISO 138491), if the operating modes are evaluated by a safety control system with safe "1oon" evaluation. Switching must not initiate a hazardous movement, nor can it cancel an existing control command.

Operating Manual PIT m2.1p DMG 1003182EN02 11 Function description Function description The operating mode selector switch enables you to switch between 5 different operating modes (operating modes OM1 ... OM4 and special operating mode OM5 (Service)). For OM1 ... OM4, one button each is available. For the special operating mode (Service), button OM1 must be operated for a certain period (see Monitoring of operating time [ 45]). Each button is assigned a monitored semiconductor output. Operating the button changes the semiconductor output from a "0" signal to a "1" signal. The operating mode selector switch guarantees that only one of the semiconductor outputs has a "1" sig nal at any one time.

"SOM" stands for "Safe Operating Mode". The outputs are assigned to buttons, which can be used to select an operating mode if they have the relevant authorisa tion (transponder key): 4.2.1 Pushbutton Output Operating mode SOM1 OM1 SOM5 OM5 SOM2 OM2 SOM3 OM3 SOM4 OM4 The operating mode OM1/OM5 is selected based on the operating time of button 1 (see Monitoring of operating time [ 45]) Switch behaviour after a transponder key is removed The change of operating mode is completed by removing the transponder key. Once the transponder key has been removed, the operating mode selector switch behaves as fol lows: Selected operat ing mode Assigned output Behaviour after the transponder key is re moved OM1 SOM1 OM2 SOM2 The previously selected operating mode is maintained. OM3 SOM3 The assigned pushbutton is backlit. OM4 SOM4 The assigned output has a "1" signal. OM5 SOM5 Switch to OM1 Pushbutton 1 is backlit SOM1 has a "1" signal Operating Manual PIT m2.1p DMG 1003182EN02 22 Function description 4.2.2 Control program requirements In order to achieve SIL CL 2 (EN IEC 62061)/PL d (EN ISO 138491) in an application, the evaluation must be carried out by a safetyrelated function block. The safetyrelated func tion block must meet the following requirements: The function block must enable safe "1oon" evaluation of the output signals at SOM1 ... SOM5. If two or more operating modes are present at the same time, this must be detected as an error. INFORMATION The function block must bridge the t1 switchover delay (see Switchover delay t1 [ 45]). If a PNOZmulti (e.g. PNOZ m1p) is used as the safety control system in conjunction with an "operating mode selector switch" function element, then this requirement is met automatically. Operating Manual PIT m2.1p DMG 1003182EN02 23 Function description 4.3 Key ID interface The Key ID interface (see Block diagram [ to a control system. 4.3.1 12]) is used to download the Key ID number Key ID number of the transponder key The Key ID number is used to clearly identify the transponder key and is unique. It is prin ted on the transponder key’s type label as a 9digit decimal figure. NOTICE Please note: The Key ID number is not printed on the transponder key packaging. If the transponder key is lost, it is impossible to supply a replacement transponder key with an identical Key ID number. The Key ID number consists of two parts: Bit 27 = 24: Key Mode (0 … 15D) Bit 23 = 00: Consecutive number (0 … 999999999D) Bit27 ... Bit24 Bit23 ... Bit16 Bit15 ... Bit08 Bit07 ...

The communication mode is configured on the Key ID interface of the operating mode selector switch (jumpers available/not available). The operating mode selector switch detects the configured communication mode at each poweron. As long as voltage is applied to the operating mode selector switch, the con figured communication mode will be active; the change in communication mode does not come into effect until the supply voltage is switched off and then on again. It’s possible to choose between the following communication modes: 4.3.2.1 Transmittercontrolled communication mode Handshakecontrolled communication mode Transmittercontrolled communication mode With transmittercontrolled communication mode, the download of the Key ID number is started by the operating mode selector switch (= transmitter). Features of this communication mode: Download of Key ID number starts once the transponder key is connected Constant bit rate (100 ms) Download on 2 data lines Constant download time (typ. 1.8 s) Monitored data download Input/outputs required on the control system: 4 inputs and 2 outputs Download is repeated by reconnecting the transponder key or if the transponder key is inserted, via the control system by sending a "1" signal to IDi0 for at least 50 ms. No special coding is required on the Key ID interface in order to download the Key ID num ber of a transponder key to the control system in transmittercontrolled communication mode. The terminals on the Key ID interface are used as follows: Key ID interface Brief description of applic ation Coding via jumpers IDo0 IDsync No configuration required IDo1 IDclock IDo2 IDout0 IDo3 IDout1 IDi0 IDin0 IDi1 IDin1 Operating Manual PIT m2.1p DMG 1003182EN02 26 Function description 4.3.2.2 Handshakecontrolled communication mode With handshakecontrolled communication mode, the download of the Key ID number is started by the control system (Request). Features of this communication mode: Download starts via a request to the control system, once the transponder key is con nected Download is repeated by a renewed request to the control system Variable bit rate (min. 2 PLC cycles per bit) Download on 1 data line Min. download time: 28 Bit * (20 ms + 2 * PLC cycle) Identifier for ID end for feasibility check Input/outputs required on the control system: 3 inputs and 1 output The Key ID interface must be coded with a jumper between IDo3 and IDi1 in order to down load the Key ID number of a transponder key to the control system in handshakecontrolled communication mode. The terminals on the Key ID interface are used as follows: Key ID interface Brief description of applic ation IDo0 IDsync IDo1 IDresponse IDo2 IDdata IDo3 Coding: OUT IDi0 IDrequest IDi1 Coding: IN Coding via jumpers IDo3 Coding: OUT IDi1 Coding: IN In handshakecontrolled communication mode, the operating mode selector switch can be operated in a functional variant. In this case the Key ID number of the transponder key is not downloaded to the control system. The control system is only used to evaluate IDo0 on the Key ID interface. In this case IDo0 is used as a signal output, enabling the control sys tem to recognise whether the transponder key is valid/invalid. With this functional variant, only 1 input is required on the control system. The unused terminals on the Key ID interface (IDo1, IDo2 and IDi0) may remain unwired ("open").

IDo0 Control line The signal is generated by the operating mode selector switch. "0" signal No transponder key is connected or the transponder key that is connected is invalid. "1" signal A valid transponder key is created. The operating mode se lector switch signals to the control system when the down load starts. The signal is present for 100 ms. IDo1 Test pulse line The signal is generated by the operating mode selector switch and indic ates the validity of the data bits at IDo2 and IDo3. IDo2, IDo3 IDi0, IDi1 Operating Manual PIT m2.1p DMG 1003182EN02 T = 100 ms Duty cycle = 50% Data lines for transmitting the Key ID number The operating mode selector switch sends the Key ID number to the con trol system via these two data lines. IDo2: Send Bit 27 … Bit 14 IDo3 Send Bit 13 … Bit 00 Data line for reading back the Key ID number The control system sends the previously received Key ID number back to the operating mode selector switch via these two data lines. IDi0: Receive Bit 27 … Bit 14 IDi1 Receive Bit 13 … Bit 00 28 Function description Download procedure [a] [b] [c] [d] [e] [f] The operating mode selector switch sets the signal at IDo0 (IDsync: control line) to "1" for 100 ms, thereby signalling to the control system that transmis sion has started. A rising edge at IDo1 (IDclock: test pulse line) indicates that the data at data lines IDo2 and IDo3 is present and valid and can be read by the control sys tem. By the time there is a falling edge at IDo1 (IDclock: test pulse line), the control system must have sent the previously read bit back to the operating mode se lector switch via the data lines IDi0 and IDi1. Before the rising edge at IDo1 (IDclock: test pulse line), the operating mode selector switch reads the bits sent back to IDi0 and IDi1 by the control system and checks it for equivalence. At least 60 ms after the falling edge at IDo1 (IDclock: test pulse line), the last bit sent back by the control system must be present at data lines IDi0 and IDi1. A maximum of 100 ms after the falling edge at IDo1 (IDclock: test pulse line), the last bit sent back by the control system must be present at data lines IDi0 and IDi1; in other words, by this point at the latest, data transfer must be com pleted and the data lines must have a "0" signal. INFORMATION If the control system does not feed back the previously read Bits correctly, the download is aborted and restarted. The "IDsync" signal is set once again. The download is repeated until the Key ID number is downloaded completely. The download of the Key ID number typically takes 1.8 s.
