Remarks
-
-
This function or function block returns cached data.
See Program a Multi-Core Controller.
- Returns the modulo-applied position of the pipe at the moment it is triggered by the Trigger Block's selected Fast Input.
- This value is only valid when TrigIsTrigged() returns TRUE.
- The Trigger block extrapolates the output value based on the timestamp of the Fast Input event to provide an accurate position even if the event occurs in the middle of a program cycle.
- Once triggered, a block has to be reset before it can be triggered again.
- All events sent to a block while in a triggered state are ignored.
- The position and time information is lost.
- Modulo Calculation: MLTrigReadPos uses the Output Modulo Position value of the previous block in the pipe, even if the previous pipe is configured for No Modulo mode.
- The previous block must specify a 0 (zero) value for Output Modulo Position before setting the Mode to No Modulo to prevent a modulo operation for MLTrigReadPosPipe.
