VIRTUAL INPUT 1(64)
There are 64 virtual inputs that can be individually programmed to respond to input signals from the keypad (via the
COM-
MANDS
menu) and communications protocols. All virtual input operands are defaulted to “Off” (logic 0) unless the appropri-
ate input signal is received.
If the
VIRTUAL INPUT x FUNCTION
is to “Disabled”, the input will be forced to off (logic 0) regardless of any attempt to alter the
input. If set to “Enabled”, the input operates as shown on the logic diagram and generates output FlexLogic™ operands in
response to received input signals and the applied settings.
There are two types of operation: self-reset and latched. If
VIRTUAL INPUT x TYPE
is “Self-Reset”, when the input signal tran-
sits from off to on, the output operand will be set to on for only one evaluation of the FlexLogic™ equations and then return
to off. If set to “Latched”, the virtual input sets the state of the output operand to the same state as the most recent received
input.
The self-reset operating mode generates the output operand for a single evaluation of the FlexLogic™
equations. If the operand is to be used anywhere other than internally in a FlexLogic™ equation, it will
likely have to be lengthened in time. A FlexLogic™ timer with a delayed reset can perform this function.
