Connection Parameters Needed for HMI/cMT Products to Communicate with a Mitsubishi L6ADP CPU 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 Mitsubishi L6ADP CPU. Configure your Controller and HMI/cMT with the following parameters to establish reliable communication.

Supported Series: Mitsubishi L6ADP CPU RS232 Series Port

HMI Settings

Parameters	Recommended	Options	Notes
PLC type	Mitsubishi L6ADP
PLC I/F	RS232
Baud rate	115200
Data bits	8
Parity	Odd
Stop bits	1
PLC sta. no.	1
