Eliminated from:
EVS93xx-EI (Servo PLC V8.0)
EVS93xx-ET (Servo PLC V8.0 with technology function)
Behaviour of the new version?
The output frequency is indicated correctly by the system block via the DFOUT_nIn_v system variable.
What happens?
The DFOUT_nIn_v system variable is permanently set to 0.
When does the problem occur?
If code C0540 (=DFOUT function digital frequency output (X10)) is configured to 0 (=DFOUT_nOut_v in %) or 1 (=DFOUT_nOut_v in rpm), the DFOUT_IO system block indicates sporadically 0 via the DFOUT_nIn_v system variable after mains switching or project download.
Which products are affected?
EVS93xx-EI (Servo PLC V7.2 and lower)
EVS93xx-ET (Servo PLC V7.2 and lower with technology function)
Possible diagnostics?
Monitoring the DFOUT_nIn_v system variable in DDS.
Short-term measures/recommendations?
Repeat mains switching or the project download if the DFOUT_nIn_v system variable indicates 0.
Evaluation:
The DFOUT_nIn_v system variable sporadically indicates 0.
