7-6Communicating 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.
