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.
