hi,

Currently I'm working on a project which requires to connect the plc Ethernet port to monitoring
device, for your information the monitoring device has Modbus TCPIP communication protocol. no any other communication protocol available.

pls guide me how to setup the Modbus setting in order the cpu could establish communication with iconics scada via Modbus TCPIP.


thanks in advance

How can you establish OPEN MODBUS / TCP communication from a SIMATIC S7 and where can you find further information?

In this webpage you will be able to download the Open ModbusTCP blocks (open the Downloads tab) and the manuals for each:

S7 OpenModbus/TCP - IT4Industry – Siemens

The downloads are fully functionnal,, so you can develop and test your application while you are purchasing the license. But your diagnostic LEDs on your CPU will remain active unitl you do install the license, and the diagnostic buffer will be flooded byerror messages so you will find it difficult to troubleshoot any other type of problem until the license is provided.

Hope this helps,
Daniel Chartier
