Switch Position, Logic In Port, Selector Control, Binary Selector

HAL SYSTEM INSTALL GUIDE The following table shows how changing the physical switch position affects the Logic In ports and the corresponding Selector control: Switch Position Logic In Port 4 3 2 1 Selector Control 1 High High High Low Selection 1 2 High High Low High Selection 2 3 High Low High High Selection 3 4 Low High High High Selection 4 A set of DR4 Logic In ports configured as a one-of selector is not a read-only control because the ports only sense when the switch closures occur - that is when the port input signal goes from logic high to logic low as described above. This means that you can link the corresponding selector control in the Processing Workspace to other selector controls and each of the participants can change the selection value. It also means that this approach works best with a physical selector that uses a set of momentary normally open push button switches. While the port is not read-only, other selectors can change and follow each other, but the physical switch cannot follow - thus the switch may not always show the proper indication. All selectors return to the physical switch setting the next time the physical switch is changed. Binary Selector 50

A set of DR4 Logic In ports configured as a one-of selector is
not
a read-only control because the ports
only sense when the switch closures occur – that is when the port input signal goes from logic high to
logic low as described above. This means that you can link the corresponding selector control in the
Processing Workspace to other selector controls and each of the participants can change the selection
value. It also means that this approach works best with a physical selector that uses a set of momentary
normally open push button switches.
While the port is not read-only, other selectors can change and follow each other, but the physical
switch cannot follow – thus the switch may not always show the proper indication. All selectors return
to the physical switch setting the next time the physical switch is changed.
