23.10.2.9 Example of a Diagnostic Status DB Query
You want to see the errors of the central module with I/O address QB 50 on the OP. This module
has two channels, channel 1 has signaled wire break.
You have selected the value "5" as the client ID.
Query
1. As long as Q_ClientID_Intern is not equal to DW#16#00000005,
Q_ClientID_User := DW#16#00000005
2. If Q_ClientID_Intern is equal to DW#16#00000005
Q_WithSubComponent := FALSE
C_AddressMode := B#16#1
C_ComponentID := W#16#8032
E_ErrorNo := 1
Q_Start := TRUE
3. Wait until Q_Start is set to FALSE
4. If Q_ClientID_Intern is not equal to DW#16#00000005,
return to step 1
