•
The slave with station address 2 supplies the value 011. This means that
the slave is installed and active.
•
The slave with station address 5 supplies the value 111. This means that
the slave is installed and active and that error information is available for
this slave. Subscriber diagnostics must be performed to evaluate this error
information. Refer to section “Performing Subscriber Diagnostics Using
DiagGetState()” for more information about this.
Diagnostic information
When READY = TRUE, the STATE provides information on the current bus
status with one of the following values:
BUSOK: All configured slaves are exchanging data with the DP Master.
BUSFAULT: One or more configured slaves are not exchanging data with the DP
master
BUSNOTCOMMUNICATION: All configured slaves are not exchanging data with
the DP master.
10.4.1.4 Performing Subscriber Diagnostics Using DiagGetState()
If the bus diagnostics have revealed that an I/O module contains diagnostic
information, then perform subscriber diagnostics on the corresponding slave.
Proceed as follows:
1.
Call 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 fieldbus address 5.
