node red istance to be interfaced to Mervis PLC
-
Hi all,
I have a stable Mervis environment with Neuron + several extension. I want use a dedicated node red instance on dedicated HW and finding a way to interface it with Mevis. There is way to read and write Mervis Global Varialbles trough Modus TCP/IP?
Thanks
Antonio

Hi @arolli,
this is theoretically possible, but the easiest solution is to spin a ModbusTCP server in the Mervis and communicate over this protocol. The BACnet/IP would be easier to interface from the Node-RED, but we don't have any Node-RED nodes tested for this. The node-red-contrib-modbus works OK.Best regards,
Martin
