Performing Subscriber Diagnostics using DiagGetState()

If the bus diagnostics have revealed that an I/O module contains diagnostic
information, then perform participant diagnostics on the corresponding slave.
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.
