corresponding documentation. 6.1 Safety-Related Inputs The module generates an internal code sequence. This sequence is monitored by a safety monitor (additional bus device) to ensure the correct order. The status of the externally connected mechanical switches controls the code sequence trans- mission. To ensure the safe state of the device, use switches with a safety function with positive opening operation. The code s ...

For details of necessary organizational measures affecting configuration of the safety monitor, please refer to the documentation for the safety monitor. Safety Classification The module contains two independent, redundant input channels. If both input channels are used, the module is suitable for use up to category 4/PL e in accordance with ISO 13849-1, or SIL 3 in accordance with EN/IEC 61508 and EN/IEC 62061. In this case, the monitor must be programmed ...

a sequence of actions. 2.2 Intended Use The device can be used as a safety module with safety-related inputs for connecting mechani- cal contacts, such as emergency-stop switches, and an optional conventional electronic out- put, e.g., to activate signal lights. When used in this way in conjunction with a programmed AS- Interface safety monitor, the device allo ...

3.5 Operating Principle 3.5.1 Safety-Related Inputs The module generates an internal code sequence. This code sequence is monitored by a safety monitor (additional node) to ensure the correct order. Figure 3.6 Code generation The status of the externally connected mechanical switches influences the code sequence transmission. Information regarding the activation of the connected mechanical switches (e.g., if the emer- gency-stop button is pressed, code transmission is inter ...
