MLTrigReadTime

 Function A function calculates a result according to the current value of its inputs. A function has no internal data and is not linked to declared instances. - Returns the time of the moment where the block was triggered in milliseconds.

Inputs

Input	Data Type	Range	Unit	Default	Description
BlockID	DINT	-2147483648 to 2147483647	N/A	No default	ID number of an initiated Trigger object.

Outputs

Output	Data Type	Range	Unit	Description
Time	LREAL	No range	Microseconds	Returns the time the Trigger Block's selected Fast Input The inputs are taken into account at each cycle depending on the system periodicity (i.e., each millisecond). Under certain circumstances, this can be insufficient when more accuracy is needed or if a quick response is required from the system. To fill the gap, a drive may have some Fast Input connections (generally one or two). When an event happens that triggers a Fast Input (e.g., when a sensor sends a rising edge), the detection of a signal occurs faster. This can be 1000 times more accurate than the system periodicity. The timestamp associated with this input can be provided to the IPC to take corrective action. was triggered.

Remarks

• 
  

• This function or function block A function block groups an algorithm and a set of private data. It has inputs and outputs. returns cached data.
  See Program a Multi-Core Controller.

• This value is only valid when TrigIsTrigged() returns TRUE.
  • The output is computed from the timestamp A sequence of characters, denoting the date and/or time at which a certain event occurred. of a Fast Input time event.
• Once triggered, a block has to be reset New start of the microprocessor. before it can be triggered again.
  • All events sent to a block while in a triggered state are ignored.
  • The position Position means a point in space which is described by different coordinates. Depending on the used system and transformation it can consist of a maximum of six dimensions (coordinates).This means three Cartesian coordinates in space and coordinates for the orientation. In ACS there can be even more than six coordinates. If the same position is described in different coordinate systems the values of the coordinates are different. and time information is lost.
