[bastien]

HELLO,

I want to know if some work or devellop a MODBUS-TCPIP plugin, to read or whrite some data on different hardware like API SHNEIDER or other ?

Thank you all,

This would be an awesome plugin, modbus rtu/tcp is the most common fieldbus in the automation industry! I have always wanted to use EventGhost to control some of my modbusTCP devices, I've seen modbus libraries written in python online can anyone integrate them into EG? Unfortunately I have no experience with EG plugins or python for that matter

MODBUS is for sure very interesting as such. Most of the people are however not so lucky to own devices and you need to find someone who has

- interest in MODBUS device integration in EG
- owns MODBUS devices
- can write a plugin in python for this

This will be very difficult as you have seen, no answers yet.

An idea would be to find an OPC Data Access Server for MODBUS. Matrikon is an example of a company that has this.

There has been some work here in this forum on OPC and I have a private plugin for EG that is acting as an OPC Client.

If you decide to follow this path I can upload my OPC Client plugin for you to test.

Best regards, Walter

Hi krambriw,

You can try to download an OPC Server for MODBUS here (free evaluation):

Then try my OPC Client plugin and see if it connects, first
unzip into the folder plugins
