Overview of the 1785ĆKA5
Communication Adapter Module
Read this chapter for information on:
what the 1785-KA5 communication adapter module is
what DH+ and DH485 networks are
compatible
products
The 1785-KA5 communication adapter module lets devices on the Data
Highway Plus (DH+) network communicate with devices on the RS-485
Data Highway (DH485) network for:
uploading/downloading of SLC 500 programs from a DH+ device
message communication between DH+ PLC processors and DH485
SLC 500 processors
The 1785-KA5 communication adapter module features:
concurrent operation as a gateway or router:
- in gateway mode, DH+ devices must initiate messages; DH485
devices cannot initiate messages
- in router mode, both DH+ and DH485 devices that implement
internet protocol (IP) can initiate messages (SLC 5/01, SLC 5/02,
and fixed controllers do not support IP)
support for existing IP
compatibility with other Allen-Bradley DH+ hardware and software
products
a baud rate of 57.6 Kbps on the DH+ network and 300bps-19.2 Kbps on
the DH485 network
