Module Error Collection Function

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 power failure, the errors can be held even after power-off or reset.
Error history (CPU module including built-in I/O and built-in
CC-Link) and error log (intelligent function module) are
displayed on one screen.
Errors that occurred in the entire system can be monitored
in reverse chronological order.

[Example of screen display]
(1) Supported module
The CPU module collects errors occurred in the connected intelligent function modules. The CPU module does
not collect errors of those modules on other stations in the network.
(2) Timing when module errors are collected
Module errors are collected in END processing. Executing the COM instruction does not collect errors.
(3) Storing module errors
The module errors can be stored either the system memory
separately from error history (CPU module) data.
*1 The memory is managed inside the system.
