Module Error Collection

This function collects errors occurred in the connected intelligent function modules in the CPU module. By storing the
errors in a memory that can hold data in the event of a power failure, the errors can be held even after power-off or
reset.Note 3.22
Error history (CPU module) and error log (intelligent function
module) are displayed in one screen.
Errors that occurred in the entire system (base units) can be
monitored in reverse chronological order.

Module A
(1) Supported modules
The CPU module collects errors occurred in the connected intelligent function modules
The CPU module does not collect the errors of intelligent function modules on other stations in the network.
*1 Indicates intelligent function modules that support this function. For supported module versions, refer to the manual for
each module.
(2) Timing when module errors are collected
Module errors are not collected during execution of a program such as the COM instruction but collected in END
processing.
Note 3.22
Universal
Before executing the function, check the versions of the CPU module and GX Works2 used.
