Communication between UniStream with Siemens Sinamics G120C

Recommended Posts

Good Morning.
I am using the unilogic version 1.25.48 to communicate with a siemens sinamics G120C inverter. No way have I been able to communicate as ethernet ip.
The communication created is based on the 2/2 Ethernet ethernet protocol telegram that works on rockwell studio 5000 v31 without problems.

I created a connection in: Project / PLC Communications / EthernetIP / Scanner
Node Name: Inverter_G120
IP Node:
RPI [ms]: 100
T2O Assembly Instance: 101
Input: Status_G120
Input Size (Bytes): 4
Use Run Idle for T2O: checked
O2T Assembly Instance: 102
Output: Control_G120
Output Size: 4
Use Run Idle for O2T: checked
Configuration: 103
Config: Empty
Config Size (Bytes): 0
Multcast: unchecked

The LED on the inverter does not stabilize in green, flashes red as no connection, and does not control the inverter. I need some help urgently!

NOTE: Created in unilogic two STRUCTS:
Status_G120.status_word - int16 [0 ... 1]
Control_G120.status_word - int16 [0 ... 1]
