Details of remote output signals
The following describes the details of the remote output signals for the master/local module.
External output signal
■Device number
■Description
This signal turns on/off the external output of output module and I/O combined module.
When a major or moderate error occurs in the I/O module, external output turns off, regardless of the status of
the external output signal.
In addition, when either of the following conditions is applied, due to the output HOLD/CLEAR setting function,
external output may operate differently than the status of the external output signal.
• The I/O module is disconnected from the data link.
• The operation status of the CPU module is STOP or it is suspended by an error.
For details on the output HOLD/CLEAR setting function, refer to the following.
