This device sends a signal to a NAiS/Matsushita PLC running a program that implements a watchdog which closes a circuit if the M&C computer stops sending signals to the PLC. The driver exclusively works with a PLC programmed in this special way.
Device window pages
The following table shows which device window pages are available with this individual device type. Tool-bar functions not mentioned here are described at the general description of device windows .

At the maintenance page of the device window there are a couple of configuration parameters which must be set to make the software talk to the alarm monitoring input at the PLC.
| parameter | description |
|---|---|
| address | The packet address of the PLC device. Usually this is "01". |
| Serial | Remember to set the line parameters for the serial interface connected to the FPx PLC device. It requires the somewhat unusual setting 9600,O,8,1 . With multiple NAIS-FP-* -devices referring to the same PLC, the line speed needs to be setup only once. |
