Connection Parameters Needed for HMI/cMT Products to Communicate with Control Technology 2500 Series 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 Control Technology 2500 Series. Configure your Controller and HMI/cMT with the following parameters to establish reliable communication.

Supported Series: CTI 2500 Series PLCs (Classic and Compact): C100, C200, C300 and C400

Device Address

Bit/Word	Device type	Format	Range	Memo
B	`CR`	DDDDD	1 ~ 65535	Internal Relay
B	`X`	DDDDD	1 ~ 65535	Discrete Input Coils
B	`Y`	DDDDD	1 ~ 65535	Discrete Output Coils
B	`V_Bit`	DDDDDdd	101 ~ 6553616	User Data Register Bits
W	`V`	DDDDD	1 ~ 65535	User Data Registers
DW	`VD`	DDDDD	1 ~ 65536	User Data Registers (32bit)
W	`STW`	DDDDD	1 ~ 65535	Status Word Registers
W	`TCP`	DDDDD	1 ~ 65535	Timer/Counter Preset Values
W	`TCC`	DDDDD	1 ~ 65535	Timer/Counter Current Values
W	`WX`	DDDDD	1 ~ 65535	Word Discrete Inputs
W	`WY`	DDDDD	1 ~ 65535	Word Discrete Outputs

NOTE: Because VD (double word) will do high and low word conversion, avoid mixing V and VD when performing data transfer and macro.
