No internal preprocessing stop is generated when these variables are read.
Note
A preprocessing stop must be programmed with
program. The system will otherwise read false values.

4.7 Measurements with touch trigger probe (MEAS, MEAW)
Command: Measuring with deletion of distance-to-go
Effective: non-modal
Command: Measuring without deletion of distance-to-go
Effective: non-modal
Trigger event to initiate measurement
Type: INT
Range of values: -2, -1, 1, 2
Note:
There are up to a maximum of 2 probes
(dependent on configuration level).
Significance:
(+)1 Rising edge of probe 1 (measuring input 1)
-1 Falling edge of probe 1 (measuring input 1)
(+)2 Rising edge of probe 2 (measuring input 2)
-2 Falling edge of probe 2 (measuring input 2)
Note:
There are up to a maximum of 2 probes (dependent on configuration
level).
