Technical Reference Manual, General
5.1.1.2. Measurement functions
The measurement function blocks are documented on the CD-ROM Technical
Descriptions of Functions.
5.1.1.3. Control functions
The control functions are used to indicate the status of switching devices, i.e. circuit
breakers and disconnectors, and to execute open and close commands for
controllable switching devices of the switchgear. Furthermore, there are
supplementary functions for control logic purposes, e.g. on/off switches, MIMIC
alarm LED control, numerical data for MIMIC and logic controlled control position
selector.
The control functions configured with the Relay Configuration Tool can be
associated with object status indicators that are part of the MIMIC configuration
picture displayed on the HMI. The object status indicators are used to indicate the
status of switching devices via the MIMIC picture and to control them locally. For
more information about the MIMIC configuration, refer to section “MIMIC
configuration” on page 35.
