Note: The FSPMS_SetSlaveDiag service only sends the Status, Module and Channel-related Blocks.

The Alarm and the Device-related diagnostic blocks are listed here only to give an overview of PROFIBUS-

defined Extended Diagnostic Blocks. These blocks cannot be sent with the service “FSPMS_SetSlaveDiag”. The

Alarm Block will be transferred separately with the service “FSPMS_C1_Alarm_Notification”. The Device-related

Block is reserved for DPV0 Slaves only.

Example:

The following example shows how to transmit an extended diagnostic with two blocks; one

channel-related and one status block. The channel diagnostic reports an “Overload”. The

status block reports a user-specific status with the string “HELP” in Slot1.
