Hello! franky1978

I tried to download the datasheet of the HMI but without success, if you got the same ready could you share.

hi Abhi,

I don't have the hmi datasheet, but in the software it's possible to set the protocol type (master slave ect)

thanks!

Hi

Without an available datasheet you might struggle. Perhaps you might find some assistance in the WiKi pages which give examples of using ModBus etc?

This is just one example

hi,
sure, i just wanted to know if anyone has ever used a wecon display with arduino using flowcode, it is not clear to me how to write on the hmi
and read from it, i have not found examples.
Do i have to put both modbus master and slave in flowcode?
thanks for the help

Flowcode team have SCADA system for industrial applications.

A simple example showing the hoppers, valves and pipes working together. Each tank automatically empties in turn.

I think you have to buy a SCADA component.
