Virtual Control Switches (43)

25 • Virtual Control Switches (43)

Five virtual control switch (43) elements provide manual control, locally and remotely, without using

physical switches and/or interposing relays.
The five, identical virtual control switch elements are designated 43-1, 43-2, 43-3, 43-4, and 43-5.

Element logic connections are made on the BESTlogic

™

Plus

screen in BESTCOMS

Plus

and element

operational settings are configured on the Virtual Control Switches (43) settings screen in

BESTCOMS

Plus

. A summary of the logic inputs and outputs and operational settings appears at the end

of this chapter.

Element Operation

Virtual control switches can emulate virtually any type of binary (two-position) switch. An example would

be an application that requires a ground cutoff switch. The traditional approach might be to install a switch

on the panel and wire the output to a contact sensing input on the BE1-11

or in series with the ground

trip output of the BE1-11

. Instead, a virtual control switch can be used to reduce costs with the added

benefit of being able to operate the switch both locally through the front panel and remotely from a

substation computer or through an Ethernet connection to a remote operator’s console.

Mode

Three modes of operation are available: Switch/Pulse, Switch, and Pulse. Because switch status

information is saved in nonvolatile memory, the BE1-11

powers up with the switches in the same state

as when the BE1-11

was powered down.

Switch/Pulse Mode

In Switch/Pulse mode, each switch can be controlled to reset, set, or pulse. Assertion of the Set input

forces the output to set (logic 1). Assertion of the Reset input forces the output to reset (logic 0). Assertion

of the Pulse input toggles the virtual output from its current state to the opposite state for 200 ms then

back to the original state. An additional Hold Time can be set when the virtual output is connected to a

physical output in BESTlogic

Plus

. See the

Contact Inputs and Outputs

chapter for more information.

Switch Mode

In Switch mode, the switch emulates a two-position selector switch, and only set and reset commands are

accepted. Assertion of the Set input forces the output to set (logic 1). Assertion of the Reset input forces

the output to reset (logic 0).

Pulse Mode

In Pulse mode, a momentary close, spring-return switch is emulated and only the pulse command is

accepted. Assertion of the Pulse input toggles the virtual output from its current state to the opposite state

for 200 ms and then back to the original state. An additional Hold Time can be set when the virtual output

is connected to a physical output in BESTlogic

Plus

. See the

Contact Inputs and Outputs

chapter for more

information.

Customized Labels

User specified labels can be assigned to each virtual switch and to both states of each switch. The labels

can be up to 64 characters long. In the previous ground cutoff switch example, you may enable one of the

switches in the Switch mode and connect the output of that switch to the blocking input of a 59X

protection element. This would disable the ground overvoltage protection when the switch is closed
