Connection Parameters Needed for HMI/cMT Products to Communicate with an Allen-Bradley DF1 using EBPro (EasyBuilder Pro)

Introduction

All Maple Systems HMIs programmed with EBPro (EasyBuilder Pro), including every cMT X Series and cMT Series model, are compatible with a Rockwell/Allen-Bradley DF1 Controller. Configure your Controller and HMI/cMT with the following parameters to establish reliable communication.

Supported Series: Rockwell/Allen-Bradley MicroLogix 1000, 1100, 1200, 1400, 1500, SLC 5/01, 5/02, 5/03, 5/04, 5/05.

Import Tags

Open ASCII Export menu

In RSLogix 500, go to Tools → Database → ASCII Export.
Configure export options
Select the CSV tab, check Addr/Symbol Desc., and enter the destination file names.
Review export result
The Export Results window confirms the export completed successfully.
Import tags in EBPro (EasyBuilder Pro)

In EBPro (EasyBuilder Pro), open System Parameter → Device. Create a Rockwell DF1 driver, click Import Tags, and select the CSV file to import.
Select tags to import

In the Add Tags dialog, select the tags to import and click OK.
Confirm successful import

EBPro (EasyBuilder Pro) displays a confirmation dialog: “Imported tag information successfully.”
