You should use compare logic to save the ECODE value in another memory location. Your
program can then test the saved error code value and begin a programmatic reaction.
Note
The error codes for the ECODE output are listed in the PLC non
-fatal error codes table (see
reference below). The error code values are in hexadecimal (16#xxxx).
