I've got one that has me baffled. Looking for a MODBus TCP to BACNet IP gateway that can poll a MODBus node having a version 6 static IP address. I've called everyone and their uncle and can't find a product that accepts v6 IP address.
For example, this particular MODBus node has an address of 2001:4888:a05:1fff:e0:22:0:49. I can ping this address, no problem. Just can't find a product that can accept v6 IP address. Does anyone know of such a product?
