OnOffDelay (FB)¶
FUNCTION_BLOCK OnOffDelay
“warp clock”-enabled on-/off-delay.
The xOutput follows xInput, but with a delay on both (rising / falling) edges.
“Warp clock”-enabled¶
Certain application domains base their functionality / algorithms on real world wall clock date/time. To develop such functionality it is helpful to have control over the application timeline to speedup testing or doesnt loose control on the timeline sitting on breakpoints. WarpClock and “warp clock”-enabled function blocks provides such a control if needed. For more details about “warp” time see WarpClock.
To use “warp” time connect an accordingly configured WarpClock to itfDateTimeProvider.
