Setting at Error Detection
Online module change setting
*1 When "Not detect" is enabled and the operating remote head module is removed, a module verification error is not detected, but an error
may occur if an program tries to access the removed module. Also, the removed CPU module will not be accessible even when it is re-
installed. Therefore, if access is tried to the re-installed CPU module through the STOP and RUN operations, it may result in an error.
*2 Set the operation of the remote head module when an error is detected by the self-diagnostic function.
When "Stop" is set, the operating status of the remote head module is set to the STOP state and the cyclic transmission is stopped.
When "Continue" is set, the operating status of the remote head module is maintained.
When the remote head module is in the STOP state, the operation is as follows.
 The transfer from the link device (RX, RY, RWr, RWw) of the remote head module to the user device (X, Y, W) is as follows.
The transfer from RY to Y stops.
The transfer from RWw to W stops.
The transfer from X to RX continues.
The transfer from W to RWr continues.
 The data transfer between the devices in the remote head module stops.
 All outputs of the remote head module are turned off.
Description
Module Verification Set whether or not to detect the module verification error.

Error
Fuse Blown Set whether or not to detect a fuse blown of the module
mounted on the remote head module.
Redundant Power Set whether or not to detect an error of the power supply module
Supply System Error at the redundant power supply system configuration.
Module Verification Set the remote head module operation at a module verification
Error error.
Fuse Blown Set the remote head module operation at a fuse blown of the
module mounted on the remote head module.
Direct change Set "Enable" or "Disable" to "Direct change setting".
setting [Precautions]
When the direct change is enabled, a minor error occurs by the
direct change.
Therefore, the operating status of the remote head module does
not change to the STOP state even if the "Module Verification
Error" of "Remote head Module Operation Setting at Error
Detection" is set to "Stop".
