Replacing every serial \u003cbr\u003edevice is expensive and disruptive. A Modbus Serial to TCP gateway \u003cbr\u003esolves this without touching a single field instrument.\u003c\/p\u003e\n\u003cp\u003eThe gateway sits between your serial devices and your Ethernet \u003cbr\u003enetwork, transparently converting Modbus RTU or ASCII requests into \u003cbr\u003eModbus TCP packets and back again. To your SCADA or HMI, every \u003cbr\u003eserial device looks like a standard Modbus TCP server on the network.\u003c\/p\u003e\n\u003ch3\u003eWhat to Look for in a Modbus Serial to TCP Gateway\u003c\/h3\u003e\n\u003cp\u003eFor industrial environments, the specification that matters most is \u003cbr\u003enot throughput it is reliability under harsh conditions.
