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