Connection Parameters Needed for HMI/cMT Products to Communicate with Parker Hannifin Compax3 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 Parker Hannifin Compax3. Configure your Controller and HMI/cMT with the following parameters to establish reliable communication.

Supported Series: Parker Compax3 Servo Drive

Device Address

Bit/Word	Device Type	Format	Range	Memo
B	`R_Low16bit`	`DDDDDDDDh`	0 ~ 99999999f
B	`R_High16bit`	`DDDDDDDDh`	0 ~ 99999999f
DW	`Register_Int`	`DDDDDD`	0 ~ 999999	For Register INT32, U32
DW	`Register_float`	`DDDDDD`	0 ~ 999999	For Register INT32, U32
W	`Register_Short`	`DDDDDD`	0 ~ 999999	For Register INT16, U16

The range of the address that can be operated depends on the address type.

For example:

If the read/write address is 1901.2, enter 190102
If the read/write address is 400.1, enter 40001
