Chapter 1 Introduction on the Communication Map

The Accura 3700 Communication Map is composed of five categories such as "System Information", "Setup",

"Control", "Measurement Data","Event Data". Accura 3700 provides Modbus Protocol-based communication. Refer to "

Appendix A Modbus Protocol of Accura 3700" for more information.

Holding registers are addressed starting at zero. Holding register address can be found by subtracting 1 from the

register number in the Modbus map. Holding registers 1 - 65536 can be accessed with the addresses 0 - 65535.
