Ref From Net
The setpoint for the FI comes via DeviceNet. Only the status of “Netref” is imaged in the control word. The
parameters P509 & P510 are not queried.

Enables the outputs of the bus module to be set, if present
Input 1 to 4
Here, up to four inputs of the bus module can be read out.
The structure of the NORD AC assemblies is shown on the basis of Instance 100/110.
If it is present in the instance, the bus module itself is always accessed in the first byte. The inputs and outputs
can be set and read out. Further functionality is not possible.
After this, the structure is always the same: the control/status word and the setpoint/actual values follow. If
several FIs are accessed in sequence, the control/status word of the next FI follows the last setpoint/actual
value.
The structure of the control and status words can be obtained from the old documentation. Setting of the
setpoint and actual values is made via the FI parameters P543 to P548.
