Introduction
An Allen-Bradley Data Highway extends the capabilities of
programmable controllers by letting them exchange data with each other
and with other intelligent RS-232-C devices. Data Highway integrates
individual controllers into a larger automated manufacturing network. On
a single Data Highway cable, as many as 64 separate programmable
controllers and computers can be connected over a distance of 10,000
feet (3,048m).
The unit that interfaces PLC-2 family programmable controllers to this
network, and makes communication possible, is an A-B Communication
Adapter Module (cat. no. 1771-KA2). (See Figure 1.1) It is a Data
Highway station interface module and is used with Bulletin 1772
programmable controller processors. These processors are:
PLC-2 Processor (cat. no. 1772-LR)
PLC-2/20 Processor (cat. no. 1772-LP1, -LP2)
PLC-2/30 Processor (cat. no. 1772-LP3)
