Introduction
All Maple Systems HMIs programmed with EBPro (EasyBuilder Pro), including every cMT X Series and cMT Series model, are compatible with an Rockwell/Allen-Bradley DF1 BCC PLC. 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.

NOTE: Allen-Bradley DF1 (BCC) and Allen-Bradley DF1 are the same; the only difference is the use of BCC checksum.
