Installation

You can connect COM1 or COM2 from the programming terminal directly
to channel 0 on the PLC-5/VME processor. This serial port supports
RS-232C only.
You can configure channel 0 to either:
user mode—Configure channel 0 to user mode when you are connecting
it to RS-232 devices such as bar code readers, weigh scales, and
message displays. You can then communicate and manipulate
instructions through the ladder-logic ASCII read and write.
system mode—This is the default. Use this configuration when
connecting to programming operators interfaces (such as 6200 series
software and ControlView) using a built-in point-to-point protocol.
Although the communication is much like DH+ link, there is no access
to DH+ through Channel 0; therefore, the channel does not require a
DH+ station address. The default baud rate is 2400.
