Which products are affected?
EVS9300-EI (Servo PLC EI from FW 1.0)
EVS9300-ET (Servo PLC ET from FW 1.0)
What happens?
If several errors of the Fail-QSP type are simultaneously triggered by the PLC program, error numbers can be repeatedly stored in the fault memory. Normally, only the first error triggered would be stored in the fault memory.
When does the problem occur?
The problem occurs if several errors of the Fail-QSP type are simultaneously triggered in several instances of the function block.
Possible diagnostics?
A higher number of entries in the codes C0168/1 to C0168/8 with the same error numbers.
Short-term measures/recommendations?
None.
Evaluation
This function restriction reduces the information about the error which occurred last, since errors which occurred before are overwritten by errors stored several times.
