Performing Device Diagnostics via DiagGetState()

If the bus diagnostics have revealed that an I/O module contains diagnostic
information, then conduct participant diagnostics on the corresponding slave. To
do this, proceed as follows:
1. Call up the function block DiagGetState() by setting the input ENABLE to
"True."
2. Specify the slave that provides the diagnostic information at the input
variable BUSMEMBERID. In this example it is the slave with the fieldbus
address 5.

the function block DiagGetBusState.
