CMC-TC monitoring system
Security – individual and flexible
The CMC-TC offers a new dimension in flexibility, efficiency,
technology and cost-effectiveness. The modular master/
slave system uses network technology as its communication
system. In the past, bus systems were used for this purpose,
but the CMC-TC system uses TCP/IP and SNMP for commu-

nication between the Master and Processing Unit II. This
gives users the option of working with high performance,
i.e. the CMC-TC master, or only with the Processing Unit II.
The standardised interface on the Processing Unit II (PU II)
allows even small individual applications to be achieved
cost-effectively. The Master II may also be used.

The new wireless sensor technology
unites the popular CMC-TC
system with radio sensors. This
transports the modular concept into
a new dimension of flexibility.
Existing IT infrastructures can also
be easily retrofitted with the wireless
sensor network.
