11.4 Error Code List
This section explains the error codes (abnormal codes) for the errors that may occur
in each processing when communicating data between the Ethernet module and an
external device as well as those generated by processing requests from the local
station's FX series PLC.
11.4.1 Type of error incident
The details of errors and error handling procedures are described.
* For error codes sent back by data communication using MX Component, refer to the MX Component Programming Manual.
