2.2.5 Device-specific parametrizing

Festo P.BE-CP-DN2-EN en 0107NH
The CPV Direct supports various device parameters by means
of which you can set the reaction of the valve control and
some status messages. The parameters are set by means of
the "Device Parameter" in the network configurator.
The table in Fig. 2/9 shows how you can address the valve
coils.
The program-controlled access by the PLC is made with the
"Explicit Message" programming. The addresses of the Devi-
ceNet Object Model necessary for this can be found in Appen-
dix B.
Reaction of the outputs in the Fault mode
If communication via the DeviceNet is interrupted, the bus
slaves assume the Fault mode. The reasons for this can be:
– Physical interruption in the network
– Interference by data telegrams.
In the Fault mode, the outputs for the valve control and the
outputs of the output module can assume one of the follow-
ing states:
– Reset the output
– Set the output
– Freeze the current status of the output.
You can determine the status to be assumed for each output
separately. The standard setting is "Reset the output".
