RS485-B Communication Plug-in Module
NOTE!
For the CFW500-CRS485-B-PNP module,
the digital inputs are fixed at active high
(P0271 = 8). It is not possible to set P0271
different from 8.
The location of the DIP-switches for selecting the type
of analog input and output signal and termination of
the RS485 line can be better visualized in
To use the analog inputs and/ or outputs with signal in
current, switch S1 and related parameters must be set as
indicated in table 2
