dropline connector over the port and twisting the collar clockwise.
If you have a KP3R module, repeat steps 1 and 2 for the port labeled Data
Highway II PORT 2.
You can connect a PLC–3 to multiple Data Highway II links. The PLC–3
requires one KP3 for each Data Highway II link it communicates over.
Follow the procedure below to connect a PLC–3 to multiple Data
Highway II links.
1. Install one KP3 in the PLC–3 chassis for each link the PLC–3 will
communicate over.
2. Select a unique module number on the thumbwheel of each KP3 in
the same chassis.
3. Connect each KP3 module to separate links via separate droplines.
