RS-485 connection for the DNP 3.0 communication module
If REF 610 is provided with the optional DNP 3.0 communication module, the cable
is connected to terminals X5.8/1-2 and X5.8/4-8. The connection socket is a 8-pin
header-type socket and the terminals are of screw compression type.
The DNP communication module follows the DNP standard and is intended to be
used in a Daisy-chain bus wiring scheme with 2- or 4-wire, half-duplex, multi-point
communication. The maximum number of devices (nodes) connected to the bus
where REF 610 is being used is 32, and the maximum length of the bus is 1200
meters in optimum conditions and with slow communication speed.
