4.1 General error response of the CoDeSys controller
Warning
If an error occurs, the controller does not stop but
continues with the program processing. Undesired
movements of the actuators can cause collisions and
severe injuries.
· Include error handling mechanisms for all error
categories in the user program.
· Make sure that no persons are in the operating range of
the drives or any other connected actuators.
The CoDeSys controller makes available the following error
handling mechanisms in user programs:
ć System event CPX_system_fault
ć Channel/module diagnosis in the flag words
ć Module support in the Festo_CPX.lib
Detailed information on error handling in user programs can
be found in the online help.
