3.20 Control and Monitoring of Switchgear Units (Function Groups DEV01 to
DEV10)
The C232 is designed for the control of up to 6 switchgear units. The topology of a
switchbay with its switchgear units is defined by the bay type.
Defining the bay type
With the selection of the bay type, the user defines the following properties:
Manually operated switchgear units with position signals to be processed
Switchgear units to be controlled and signaled by the C232
The bay interlock equations for the Open / Close control of the switchgear units, for
operation with or without station interlock
Binary inputs required for switchgear units with direct motor control
Outputs required for switchgear units with direct motor control
When the bay type is selected, the binary inputs for the switchgear position signals and
the output relays for the control commands are configured automatically if
MAIN: Auto-assignment I/O is set to Yes. If set to No, the user will need to carry
out this configuration. The list of bay types in the Appendix shows which binary inputs
and output relays have been assigned signals or commands for control of the switchgear
units in the case of automatic configuration.
The setting options for the C232 and the different possibilities for integrating a
switchgear unit into the functional sequence of the C232 (processing position signals
only or controlling and signaling) will be explained below, using one switchgear unit as
an example. Function group DEV01 will be used throughout in this example.
If a signal is identified in the function diagrams by function group “COMM1:” and a blank
address [--- ---], this means that it is a signal to or from the communication interface and
that no address has been assigned to it. The signals listed in the function plans as
‘signal 1’ to ‘signal n’ are specified in the configuration tables of the Address List.
