2.3.2 Master Control Element
The master control element is the heart of the system SICAM MIC. The hardware of the mas-
ter control element is the master control module, and its functionality is provided by means of
a loadable and parameter-settable firmware.
On the master control module CP-6020 reside an inter-
face for the communication (serial), digital inputs and
outputs, as well as a lighted display.
On the master control module CP-6040 resides addition-
ally an interface for the communication via Ethernet.
The master control element contains all the central functions for processing and communica-
tion, and it provides the parameter-settable
telecontrol function and the open-/closed-loop func-
tion
.
Furthermore, the master control element is able to store events in an archive (DEAR) in case
of a communication fault. After elimination of the fault the superior control system can demand
the archive of the master control element. By means of this function, a possible data loss will
be prevented.
