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.

Function description 4.1 Interface for status information Various status information can be signalled via the interface for status information (see Block diagram [ 12]). The status information can be evaluated through a control system. The status information is subdivided into the following information classes: } } Operator actions – Insert transponder key – Remove transponder key – Select operating mode Messages (e.g.
Function description [1] When a pushbutton is released, information as to which transponder key is used will be displayed for 200 ms (see Status information 2h and 4h … 7h). The selected operating mode is then displayed (see Status information 3h and 8h … Bh). Please refer to the Timing diagrams for operator actions [ 16].

Function description 4.2 Operating mode interface The operating mode interface consists of the monitored outputs SOM1 … SOM5 (seeBlock diagram [ 12]). "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.
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.
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.
Function description Examples: Key-ID-Number: 130000044 1101 0000 0000 0000 0000 0010 1100 Consecutive number: 44D Key Mode Service Key-ID-Number: 020000510 0010 Key Mode 02 Operating Manual PIT m2.
Function description 4.3.2 Communication mode for downloading the Key ID number The unique Key ID number for the relevant transponder key is downloaded to the higher level process control system using a defined protocol, depending on the configured com munication mode. 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.
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.

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.

Function description tIDend End of Key ID Number Transfer (200 ms) After the last falling edge at IDi0, the operating mode selector switch still has a "1" signal at output IDo1 for 200 ms. In this way, the end of the Key ID number and therefore the end of the download (End of Key ID Number Transfer) is dis played. This can be used for the feasibility check.
