7-4 Communicating with a PLC-5 Adapter Channel
In this Field
Define
By Doing the Following
Diagnostic file
The file containing the adapter channel’s
status information
Cursor to the field and enter an integer file number (9-999).
ATTENTION:
Assign a unique diagnostic file to each channel. Do
not assign a diagnostic file that is the I/O status file you
assigned or any other used integer file. Unpredictable machine
damage can result.
Important: You must define a diagnostics file for a channel
configured for anything but unused (even if you are not using the
channel) if you want to get status information for that channel.
Baud rate
Communication rate for the remote I/O
link
Cursor to the field and select the desired rate.
Available rates are: 57.6, 115.2, or 230.4 kbps.
Rack number
The rack address of this PLC-5 controller
as it appears to the scanner
Cursor to the field and enter the address.
Valid addresses are (based on the scanner this PLC-5 controller
communicates with):
3 octal (PLC-5/11 controllers)
1-3 octal (PLC-5/20, -5/20E controllers)
1-7 octal (PLC-5/30 controllers)
1-17 octal (PLC-5/40, -5/40L, -5/40E controllers)
1-27 octal (PLC-5/60, -5/60L, -5/80, -5/80E controllers)
The default is rack 3.
Important: The valid addresses are based on the scanner, not
the PLC-5 controller you are configuring. For example, if you are
configuring a PLC-5/20, you could enter a rack address between
1-27 if the scanner you will be communicating with is a
PLC-5/60.
