Communicating with a PLC-5
Adapter Channel
Using This Chapter
This chapter explains how to configure the controller to communicate with an
adapter channel:
1. Select which channel to configure as an adapter.
2. Define a diagnostic file.
3. Use a unique, unused integer file.
4. Define the rack address, starting group and rack size.
5. The default rack address is rack 3.
6. Define the discrete transfer files (enter as decimal numbers).
7. The input source is where the supervisory controller’s output discrete
bits go (default is 001:024 - the decimal representation of rack 3). The
output source is where the supervisory controller’s input bits go (default
is 000:024).
8. Create the necessary block-transfer control files (one BTR and one
BTW).
9. Configure the block-transfers so the supervisory controller knows
where to address block-transfers.
