7-6 Communicating with a PLC-5 Adapter Channel
Configure the discrete transfer configuration file as an integer file. Although
the PLC-5 controller allows you to use the input or output areas, reserve these
for real I/O on scanner channels. In doing so, you are avoiding a possible
conflict if you later attempt to add a rack that uses the same I/O image space.
IMPORTANT
Do not configure the adapter channel’s discrete transfer
configuration input destination file to be the data table
input image. You risk clearing inputs when performing an
autoconfiguration for a scanner channel on the
same controller.
The adapter inputs will not be updated until a change is
detected in the input data being sent by the controller.
