Chapter 4: Communication-Based Operation
4.6.3 Dummy input signal
Sets the input signal via communication, regardless of the value of the input signal from
the controller. This function can be effective when, for instance, isolating problems
during troubleshooting. For example, if the control valve does not move in response
to input signals from the controller, but the valve operates correctly in response to the
simulated current input, it follows that the problem is somewhere between the wiring
and the host system.
■ Dummy input signal configuration procedure
Step Procedure
1 Select [Device] >> [Maintenance] >> [Simulation] >> [Dummy Input Signal].
2 Select a dummy input signal ([0%], [50%], [100%], or [Other]) from the [Dummy Input
Signal] menu.
3 If you selected [Other], enter a value (0 to 100%).
4 To cancel the dummy input signal, select [Clear] from the [Dummy Input Signal] menu.
5 To exit the [Dummy Input Signal] menu, select [Exit].
4.6.4 Dummy Drive Signal
Cuts off the drive signal from the PID control unit, and applies the dummy drive signal
to the EPM (electro-pneumatic module).
■ Dummy Drive Signal configuration procedure
Step Procedure
1 Select [Device] >> [Maintenance] >> [Simulation] >> [Dummy Drive Signal].
2 Select a dummy EPM drive signal ([0%], [50%], [100%], or [Other]) from the [Dummy
Drive Signal] menu.
3 If you selected [Other], enter a value (0 to 100%).
4 To cancel the dummy EPM drive signal, select [Clear] from the [Dummy Drive Signal]
menu.
5 To exit the [Dummy Drive Signal] menu, select [Exit].
