Remedied from:
EVS93xx-EI (Servo PLC V7.0)
EVS93xx-ET (Servo PLC V7.0 with technology function)
Behaviour of new version?
If the SYSTEM_bPLCResetAndRun system variable of the SYSTEM_FLAGS system block is set to TRUE a control reset is activated and the PLC target system is restarted immediately.
The PLC_ColdStart system POU is started first after the PLC target system restart.
Which products are affected?
ECS axis module B-SW <= V6.7
EVS93xxEI (Servo PLC V6.x)
EVS93xxET (Servo PLC V6.x equipped with technology function)
EPL-10200 (Drive PLC V6.x)
What happens?
The SYSTEM_bPLCResetAndRun system variable of the SYSTEM_FLAGS system block is designed to execute a control reset and to restart the PLC target system.
If the SYSTEM_bPLCResetAndRun system variable is set to TRUE a control reset is not activated. The PLC target system continues to run irrespective of the system variable state.
When does the problem occur?
The SYSTEM_bPLCResetAndRun system variable is without function.
Possible diagnostics?
None.
Short-term measures/recommendations?
Use code C2108 to reset and restart the PLC target system.
Evaluation:
By means of the SYSTEM_bPLCResetAndRun system variable the PLC target system can be reset without mains connection. This variable is quite seldom used in practice.
