Extended Error Information Field
Depending upon the value in the module error field, the extended
error information field can contain error codes that are
module-specific or common to all 1769 analog modules.
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 modules generate 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 modules, which continue to operate
with their previous configuration.
TIP
If no errors are present in the module error field, the
extended error information field will be set to zero.
