Circutor CVM-B100 - 7.5.- MODBUS;TCP BRIDGE COMMUNICATIONS MODULE

7.5.- MODBUS/TCP BRIDGE COMMUNICATIONS MODULE
The M-CVM-AB-Modbus TCP ( Bridge) is a communications module for connecting the
CVM-B units to a Modbus/TCP network and as an Ethernet to RS-485 gateway.
Modbus/TCP is a communications protocol designed for enabling industrial units 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 congure and monitor a unit via the Internet.
The communications module is also equipped with an RS-485 gateway.
