Specifies the lower limit position of the trigger
event valid area. The valid area includes the
lower limit position.
Specifies the upper limit position of the trigger
event valid area. The valid area does not include

Compensates the delay time of the touch probe
process. Set a positive value to compensate for a
delay.
Sets the latch method of the data.
0: OneShot: One shot mode
1: RecordCount: Number of designation times
mode
2: RingBuffer: Ring buffer mode
Sets the number of latch times.
Sets the storage location of latch data. When it is
omitted, latch data is output only in
RecordedPosition.
Description
When TRUE, it indicates the output value is valid.
Indicates that the FB is in execution.
Indicates that an execution of FB is aborted by
error and multipul start.
Indicates that an error has occurred in the FB.
The error code generated is returned.

Page 534 List of Error Codes
Stores the current value of data to be latched.
Stores the current value when a trigger event is
occurring. When latch is executed multiple times,
the data is overwritten by the latest data.
Stores the number of times that latch is executed.
Stores the ID unique to this FB.
