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 DH485. 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.

Slot Configuration
NOTE: EBpro V6.07.02 or driver version V1.70 and later do not need to set Slot Configuration. Only older versions need to set this item.
Import Tags
-
Export Tag Database
In RSLogix 500, navigate to Tools → Database → ASCII Export.
Configure Export Settings
Select the CSV tab, check Addr/Symbol Desc., and enter the destination file names.Select Export Destination
Browse to the desired destination directory and confirm the selection.Confirm Export Result
The Export Results dialog confirms the address/symbol description database has been exported to CSV format.
Import Tags in EBPro (EasyBuilderPro)
In EBPro (EasyBuilderPro), go to System Parameter → Device. Create a Rockwell DH485 driver, click Import Tags, and select the CSV file to import.

Wiring Diagram
NOTE: The serial port pin assignments may vary between HMI models.
Diagram 1: RS-232 (9P D-Sub to 8P Mini-DIN)
MicroLogix 1000, 1100, 1200, and 1500 must set DH485 protocol. The following is the view from the soldering point of a connector.
