Modbus Communication

Modbus/TCP
The Modbus/TCP protocol is used on Ethernet communication. The XTDL-HT™ supports traditional IPv4
internet layer and EUI-48 MAC addressing. Each Ethernet device on a local network must have unique
address. If multiple XTDL-HT™ instruments are installed, each unit must be configured to a unique MAC
address and a unique IP addresses. New address goes into effect once power to the instrument is
recycled.
