Reset the remote head module or turn off and on the power, and click the [Update] button.

Check that "Valid" is displayed for "Module Status".
• If a module that is already enabled is attempted to be enabled, the status does not change to "Valid (Reset
Wait)" while the status is in "Valid".
• When changing a module parameter of the R60AD8-G, the safety module needs to be enabled again.
• When the safety module is enabled or disabled, the enabled/disabled state is saved in the flash memory in
the module, but note that the number of rewrite operations is limited. The enabled and disabled states can
be written up to 250000 times in total. If the number of write operations exceeds 250000, a number of safety
module status switching exceeding limit error (error code: 1081H) occurs. In this case, a write operation of
the enabled/disabled state is executed, but the result is not guaranteed.
Description
The information is not acquired.
The safety module has just been enabled. In this state, the R60AD8-G needs to be reset, and the module
status will be enabled after the reset. At this time, the ALM LED flashes every 0.4 seconds.
The module parameters are different between the SIL2 Process CPU project and the remote head module
project. Check that the module parameters are consistent.
The safety module failed to be enabled. Check wiring or other items and retry it. If the error occurs again, the
possible cause is a failure of the module.
A timeout occurred because no response was returned from the target module. Check the settings or status
of the target module. ( Page 314 When "Timeout" is displayed for "Module Status")
