Remedy
---
Start the application with a reset via the
mode selector switch or in the connected
IDE.
If the application cannot be started,
restart the controller.
Contact WAGO Support if the error
occurs again.
Try to reduce the load on the system:
- Change the CODESYS program.
- End any fieldbus communication that
is not essential, or reconfigure the
fieldbuses.
- Remove any non-critical tasks from
the RT area.
- Select a longer cycle time for IEC
tasks.
Resume the application in the connected
IDE with single step or start.
Remove the breakpoint if necessary.
If the connection has been interrupted,
set the mode selector switch to "STOP"
and then back to "RUN" to enable the
application to continue
Enable a runtime system, e.g., via the
WBM.
Remedy
Check network connections and network
settings.
