Circutor CVM-B100 - 7.10.- MODBUS;TCP SWITCH COMMUNICATIONS MODULE

7.10.- MODBUS/TCP Switch COMMUNICATIONS MODULE
The M-CVM-AB-Modbus TCP (Switch) is a communications module for connecting the CVM-B
units to a Modbus/TCP network and as an Ethernet to Ethernet 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.
