Programmable controller 1785-L20B is the main part of each control system based on the AB PLC-5 series. 1785-L20B merges I/O modules—including local, extended, and remote devices—on various types of communication interfaces into one coherent control system suited for various process control challenges. 1785-L20B has one built-in port dedicated for Data Highway Plus (DH+) communication interface. That port is marked as channel 1A. Besides that, 1785-L20B has one port that can be configured both as DH+ or Remote I/O (adapter or scanner). This port is marked as channel 1B. DH+ communication can be used both for remote programming and monitoring the 1785-L20B, and for creating a peer-to-peer communication network between the other various PLC-5 controllers. Remote I/O connection is used for real time data exchange between the controller and an I/O operator interface and other devices. On the front panel of 1785-L20B controller, there is a 25-pin connector marked channel 0. This is an optically isolated EIA RS232C port. Channel 0 supports ASCII and DF1 full-duplex, half-duplex master and half-duplex slave protocols. On the front panel, there is a channel 0 communication green indicator light. Besides channel 0, there is 8-pin mini DIN connector marked as channel 1A. This is a DH+ programming terminal connection parallel to channel 1A. There are two three-pin connectors and they are used as communication ports. One is marked as channel 1A and that port is dedicated to DH+ communication and there is port channel 1B which can be configured as remote I/O scanner, remote I/O adapter or DH+ communication port.
