I/O Mode - Mitsubishi Electric MELSEC iQ-R Series Programming Manual

I/O mode

The following describes the simulation function (SIMULATION mode), override function (OVERRIDE mode), and tag stop
function (TAG STOP mode). For the overview of I/O mode, refer to the following.
Page 21 I/O modes
Simulation function (SIMULATION mode)
This function performs simulations without actual input/output for I/O modules.
Execute the simulation function (SIMULATION mode) after changing the mode to SIMULATION with I/O mode change of the
faceplate. For details on I/O mode change, refer to the following.

Description
The loop control is executed by using MV output as feedback input while the PV external output and MV external input are
not executed (with the input and output separated from the external). The loop test separated from the actual plant can be
performed.
The input and output are separated from the external and the input signal is substituted a certain period after the output
instruction is received. The actual valve ON/OFF instructions and response of answer signal can be simulated to confirm
the control operation.
Description
The simulation data of the loop tag FB can be created by returning the simulation output (SIMOUT) to the simulation input
(SIMIN) as variable in the tag FB.
Creation of program which returns input to output is not required. Set the simulation answer back signal period (SIMT) of
tag data.
