Communicating through the 1785ĆKA5
Communication Adapter Module
This chapter includes information on:
network addressing
how the 1785-KA5 module operates as a router
how the 1785-KA5 module operates as a gateway
PLC-5 to SLC communication
controlling the flow of data
Each station on the internet must have a unique Internet Protocol (IP)
address to help a packet reach its intended receiver. The IP address is the
high level address used to send message packets back and forth across the
internet. The IP address must be unique over all physical networks that are
connected, not just one local network channel. It is needed because a
device on the DH+ network may have the same address as a device on the
DH485 network. The IP address has two parts:
LINK_ID address
DH+/DH485 STATION address
LINK_ID Address
The LINK_ID is the address of the link (individual cable or channel). Each
network link in the internet should have a unique LINK_ID address. You
set the LINK_ID address using the switches on the interface module for
each station.
Important: If more than one 1785-KA5 module is attached on one
physical link, each must have the same LINK_ID address.
