A discrete I/O connection to the 1771 I/O chassis must exist before a connection may be established to an intelligent

module in that chassis. This document does not cover the theory and practice of ControlNet I/O mapping with PLC-

5C15 controllers. If you are unfamiliar with the Scanlist Editor, contact your local Rockwell Automation

distributor or support office.

In the RSNetworx for ControlNet Scanlist Editor, right-click on the entry for the 1771-Generic module in the chassis

you have chosen, and select “Insert Connection”. The software will enter Edit Mode and the Module Connection

Properties window will appear.

Enter the desired number of

words into the Input Size field

in the Connection Properties

dialog.

Remember that the 1771-IFE

Input Data may be either

41 words or 64 words in

length.

If you intend to use scheduled

I/O messaging to perform

configuration of the module,

you may also enter either

5, 23, or 64 words in the

Output Size field of the

Connection Properties dialog.

Because a CIO instruction is

used to configure the module,

set the Configuration Data size

to 0 words.

The Input Address chosen in the Connection Parameters dialog has already been chosen as the ControlNet Data

Input file in the PLC-5. Input data from the module will be mapped into PLC-5 data file memory starting at that

address.
