A Second Link
To provide a second communication link at a data highway station, you
can connect a KA2 module to another KA2 or to an A–B 1771–KG
(series B) interface module to provide an RS–232–C link and a Data
Highway link. These links enable communication with, say, a PLC–2
family processor on the highway, and a stand–alone computer.
In such a scheme, the 1771–KG module can be connected directly to the
PLC–2 family processor, and the KA2 connected to the PROGRAM
INTERFACE connector of the 1771–KG, or vice versa.
