Error Codes
Error codes can help troubleshoot your module.
During system configuration, if you set the fields in the configuration
file to invalid or unsupported values, the module generates a
configuration error and the system controller enters a Fault condition.
The invalid configuration data must be corrected and the program
downloaded again for the system to enter Run mode. You cannot
change module configuration data while the system is in Run mode.
Any changes are ignored by the module, which continues to operate
with its previous configuration.
