3.20.2 Functional Sequence for Controllable Switchgear Units
Local or remote control of
external devices
Switchgear units can be controlled remotely or locally. The Selection of the Control
Point is described in the section entitled “Configuration of the Bay Panel and of the
Measured Value Panels; Selection of the Control Point (Function Group LOC)”. Usually,
remote control is effected via the communication interface, local control via the local
control panel keys. Moreover, the switching devices can be controlled remotely via
binary inputs configured appropriately (configuration via DEVxx: Inp .asg. el. ctrl.
open or DEVxx: Inp. asg. el. ctr. close). The setting MAIN: Electrical
control determines whether the inputs function as remote or local control points.
Selection of the switching
device to be controlled and
generation of the switching
request
The switchgear unit to be controlled is selected and the switching command is sent to
the selected switchgear unit. This can be effected via the local control panel using the
selection key and pressing the ‘Open’ or ‘Close’ key to generate the switching request.
For control via the binary inputs, the appropriate control inputs need to be configured for
the switchgear units to be controlled. For control via the serial interface, the control
command ‘Open’ or ‘Close’ also addresses the switchgear unit to be controlled.
