How can you read out diagnostics data from a SIRIUS 3RK3 modular safety system using a S7-300/400 CPU?

Part number:

Description
The "MSS_DIAG" block available for downloading in this FAQ permits you to diagnose a SIRIUS 3RK3 modular safety system(MSS) from an S7-300/400 controller. Here, the block reads out specific data records in the MSS and stores the diagnostics data in an associated instance data block. You can read out the diagnostics data from this data block and use it in the user program or have it displayed on an HMI.
