Overview
1-5
The following diagrams show three basic configurations for programming
and debugging your ladder-logic programs.
Connect a computer via the DH+ link, typically using a
1784-KT communication device in your IBM AT

computer
and a 1784-CP6 cable.
Connect a computer using the RS-232C on-board serial
port of the PLC-5/VME processor. In this configuration, the
RS-232C cable connects one of the computer’s COM ports
to the channel 0 (serial) port of the processor.
You can program as well as download files directly over the
VMEbus backplane to your PLC-5/VME processor if you:
run 6200 Series PLC-5 Programming Software release
4.4 or later
use an 8086-based CPU from RadiSys—i.e., a EPC-1,
EPC-4, or EPC-5 VME PC-compatible computer.
Important: In order to use the save feature of the 6200
Series PLC-5 Programming Software when you
communicate with the processor in this way, you must run
release 4.5 or later.
