2.2.6 Device-specific parametrisation

2-20
The CDVI-DN supports various device parameters which
you can use to set the reaction of the valve control and sev-
eral status messages. The parameters are set by selecting
"Device Parameters" in the network configurator.
The table in Tab. 2/4 shows an example of how to address
the solenoid coils.
Program-controlled access to the PLC is made by "explicit
message" programming. The addresses of the DeviceNet
objects required for this purpose can be found in Appendix B.
Reaction of the outputs in fault mode
The bus stations assume fault mode if there is a fault in the
communication via DeviceNet. These faults may be caused
by:
– Physical interruption of the network.
– Interference to data telegrams.
In fault mode, the outputs for valve control and for the output
modules can assume one of the following states:
– Reset output
– Set output
– Freeze current status of output
The status to be assumed can be determined separately for
each output. The default setting is "Reset output".
