MC_AbortTrigger

Description

When the Execute input transitions from low to high, this function block aborts an MC_TouchProbe function block.

Arguments

For more details on how inputs and outputs work, refer to PLCopen Function Blocks - General Rules

Input

Execute	Description	Enables execution
	Data type	BOOL
	Range	0, 1
	Unit	N/A
	Default	—
Axis	Description	Specifies the axis that was specified in the MC_TouchProbe function block which is to be aborted
	Data type	AXIS_REF
	Range	[1,256]
	Unit	N/A
	Default	—
TriggerInput	Description	Specifies the Fast Input The inputs are taken into account at each cycle depending on the system periodicity (for example 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 (which can be 1000 times more accurate than the system periodicity). Then the timestamp associated with this input can be provided to the IPC to take corrective action that was specified in the MC_TouchProbe function block which is to be aborted. The elements of TriggerInput are as follows: InputID INT; 0 = Touch Probe 1 / Capture Engine 0 1 = Touch Probe 2 / Capture Engine 1 Range is [0,1] Direction INT; 1 = rising edge A rising edge is the transition of a digital signal from low to high. It is also called positive edge, 2 = falling edge Range is [1,2] TrigID INT; is the axis number of the input. 0 indicates that the trigger axis is to be the same as Axis.AXIS_NUM. Range is [0,256] TrigMode INT (TriggerInput.TrigMode) is not presently supported by this function. The TriggerInput.Mode may be supported in a future software version.
	Data type	TRIGGER_REF
	Range	See Description above
	Unit	N/A
	Default	—

Output

Done	Description	Function block has completed
	Data type	BOOL
Busy	Description	Indicates the function block is currently executing
	Data type	BOOL
Error	Description	Indicates the function block did not complete due to an error. The ErrorID output indicates the type of error when this output is high
	Data type	BOOL
ErrorID	Description	When the Error output is high, this output indicates the type of error. When the Error output is low, this output is undefined See table in PLCopen Function Block ErrorID Output
	Data type	INT

Usage

This function block is used to abort an MC_TouchProbe function block.
