Appendix A Modbus Communication Protocol

A.1 Summary

We provide general RS485 communication interface in our inverters for the user. Through

this communication interface upper device (such as HMI, PC, PLC controller and etc.) can
perform centralized monitor to the inverter (such as to set inverter parameter, control run of
inverter, read work state of the inverter).
This communication protocol is interface criterion file designed for realizing
above-mentioned function, please read it earnestly and program according to it so that realize
long-distance and network control to the inverter.

A.2 Communication networking mode

Fig.A-1 Networking graph

A.3 Communication mode

At present,EN600PV inverter can be used only as Slave device in RS485 net. Can realize

communication between inverters through PC, PLC or HMI if it needed. Specific communication
mode is as mentioned below:

(1) PC or PLC as mainframe

，

inverter as Slave device, point-to-point communication

between mainframe and Slave device.

(2) Slave device don’t response when mainframe send out command by broadcast address.
(3) User can set local address, baud rate and data format of the inverter through Slave device

keypad or serial communication mode.

(4) EN600PV provides the RS485 interface.
(5) Default mode: Asynchronous serial

，

semiduplex transport mode. There are RTU and

ASCII two mode . Default format and transport rate: 8-N-1, 9600bps.

A.4 Transmission mode

Asynchronous serial, semiduplex transport mode. Default format and transport rate: 8-N-1,

9600bps. The detail setting parameter, please refer to the F05 group function mode.(Remark: the
parameter is valid under the Modbus communication, the other parameter comply with the original
service manual)

mainframe is PC
