HMI Proface “Modbus RTU” Siemens Sinamics V20 Tutorial

Written by plc247.com

Hello, in previous posts plc247.com guided you to use HMI Proface to control many different devices using Modbus RTU Communication Standard.

Today plc247.com continues to guide you to control Siemens Sinamics V20 inverter with Proface GP4402WW (both devices have built-in RS485 port)

HMI Proface & Sinamics V20 “Wiring Diagram”

Siemens Sinamics V20 “Modbus RTU” Setting

In order for the inverter to be controlled by Modbus RTU, we need to set the following communication parameters

Registers Control Address
Note: GP4402WW HMI Address = “400001 (dec) + Device Address”

>>> Motor Control Address = 400001 + 99 = 400100

  • Set Word 400100 = 1151 >>> Forward Run
    = 3199 >>> Reverse Run
    = 1150 >>> Stop
    = 1278 >>> Reset

>>> Frequency Setting Address = 400001 + 100 = 400101

  • Reference Setting = [0 to 16384] = [0 to 100%]
Registers Monitoring Address

>>> Motor Status Address = 400001 + 109 = 400110

Proface HMI Modbus Configuration

We need to set the communication parameters of the HMI Proface the same as those set in the Sinamics V20 VFD
