But may be ability exists in STEP7 to require directly the simlest diagnostic information from that and all another modules: correct or incorrect? It is a maximum information I would like to get from HW modules. This is concerned inside ET200S modules also. Thanks.

Moreover, the diagnostic data are needed to process errors automatically (to switch equipment to safe state and eliminate some actions). Now I study ability to use SFC 51 to do that processing. Does exist clear examples of using SFC51 in STEP7 helps or manuals? Give me references if any. Thanks.

Look at How do you read out the operating state and status of an H system?and How can you read out the serial number of the MMC? Hope these FAQs will help. Best regards, Hristo Mihalev
