7�5�- MODBUS/TCP BRIDGE COMMUNICATIONS MODULE
The M-CVM-AB-Modbus TCP (Bridge) is a communications module for connecting the CVM-B 150
devices to a Modbus/TCP network and as an Ethernet to RS-485 gateway.
Modbus/TCP is a communications protocol designed for enabling industrial devices to communicate
with each other on Ethernet networks using TCP/IP protocols.
Basically, Modbus/TCP encapsulates a Modbus frame within a TCP frame, making it possible to
configure and monitor a device via the Internet.
The communications module is also equipped with an RS-485 gateway.
