Venus and color control. Can they work together in the same system to increase input numbers? or Venus can control external I/O module?

Hello,

I have a question about Venus and color control. Can they work together in the same system to increase input numbers? or Venus can control external I/O module?

Thanks

No, they can't operate in a master / slave configuration.

There isn't an expansion module for I/O.

Depending upon what you are wanting to do, maybe you can communicate with the device with MQTT or Modbus-TCP with an external device?

Hello,

Thank you for your answer. Actually, I need more relay outputs to control actuators for PV panels. So do you advice if I need more input and/or outputs how can I manage with Venus OS

Thanks

Not sure if this is still relevant/needed, but I am using an Industrial Shields Arduino PLC (relay type), which I plan to read Venus GX PV data, via Modbus TCP. If you used a similar system, you would have to program the Arduino for the relay operation, (and to read the Modbus registers of the Venus) for your PV switches/relays. Some off the shelf PLCs may also give this functionality, (eg Siemens) although not sure how you would go programming those PLCs to read the Modbus registers from the Venus, via TCP. Just a thought...
