savvyPanel
SR Latch
Description This function block has both a Set and Reset function for Output.

When the Reset is Enabled, Output is set LOW (0).
When Set is Enabled, Output is set HIGH (1).

Order of Precedence: Reset => Set.

Output is writable, which is the important distinction between this Function Block, and the Latches -> SR Latch Function Block (its Output is read-only). Copy the Output parameter into the savvyPanel system for a second input to set the state of the latch output.

Output is not persistent (stored) when powered-down.
