Issue
Eventlist in StruxureWare workstation is filled very rapidly with the following messages:
- * Modbus group re-factorized
- * Modbus group factorized
- * Modbus illegal data address
Environment
StruxureWare Building Operation 1.4.818
Cause
The problem is that it is illegal registers in the Modbus register group or groups.
Modbus is trying to resolve this by refactoring the factoring and refactoring but is not successful.
Resolution
The possible solutions are:
- Identify the illegal Modbus point in SmartStruxure and remove from the subscription. Solution
- Split the group in to two so that the illegal Modbus point is left out of the groups.
-
Disable group poll and Force individual point polling by setting incorrect function code for the group.
If it is difficult to identify the illegal Modbus point then you can use solution 3 to do this.
