11.7.3 RI/O STOP input signal

The RI/O STOP input signal is a signal used to externally control the stopping of remote I/O communications.
When the RUN/STOP switch of the CPU module is set to RUN and the LADDER RUN/STOP switch is set
to RUN, you can control the operation or stoppage of a remote I/O transfer by using the ON/OFF contact of
the RI/O STOP input terminal on the RI/O-IF module.
Figures 11-16 and 11-17 show the operation timing for remote I/O communications.

• One sequence cycle is the time specified by using LADDER SYSTEM.
Alternatively, it is the time to run a longer ladder program once.
• One refresh cycle is the time for remote I/O communications for the specified points.

Note: When LADDER MODE is set to "SIMU", the remote I/O communications are in a stop state.

Note: When LADDER MODE is set to "SIMU", the remote I/O communications continue in a stop state, even if
the RI/O STOP input terminal changes from ON to OFF.
