3Z4L Laser Micrometer Protocol

The 3Z4L Laser Micrometer Protocol is used to make various settings or control remotely the Laser Micrometer connected to the Serial Communications Board via RS-232C cable.

Protocol Configuration

The configuration of the 3Z4L Laser Micrometer Protocol is shown below.

Sequence	Communications sequence	Function	Ladder interface
No.	name
			Send word	Receive
			allocation	word
				allocation
400	3Z4L clear	Resets errors, data, analog output, deci-	No	No
		sion result and places the Laser Microme-
		ter into standby.
401	Memory switch set	Sets memory switches and the area for	Yes	No
		the work position LED.
402	mm unit set	Sets the display unit to mm.	No	No
403	E unit set	Sets the display unit to E.	No	No
404	Calibration set	Calibrates the Laser Micrometer.	Yes	No
		Calibration setting release.
405	Calibration release	Releases the calibration of the Laser Mi-	No	No
		crometer.
406	Program number set	Switches the program number to a speci-	Yes	No
	(3000-series)	fied number.
407	Measurement condition set	Sets measurement conditions.	Yes	No
	(3000-series)
408	Measurement condition re-	Releases measurement conditions that	Yes	No
	lease (3000-series)	have been set.
409	Measurement condition list re-	Requests the measurement conditions	No	Yes
	quest (3000-series)	that have been set and other settings.
410	Single run measurement start	When the sample measurement condition	No	Yes
	(3000-series)	is from 1 to 999, performs a single run
		measurement and requests the measure-
		ment results.
411	Zero run measurement start	If the sample measurement condition is	No	No
	(3000-series)	zero, starts a zero run measurement.
412	Continuous measurement	Starts a continuous measurement. The	No	Yes
	start (scan) (3000-series)	scan notification method is used for re-
		ceive data.
413	Continuous measurement	Starts a continuous measurement. The	No	Yes
	start (interrupt) (3000-series)	interrupt notification method is used for
		receive data.
		Measurement termination (3000-series)
414	Measurement termination	Terminates a continuous measurement.	No	No*1
	(3000-series)
415	Data request (3000-series)	Requests display data in the idle mea-	No	Yes
		surement status or the latch data gener-
		ated by the measurement command.
416	Statistic processing execution	Lights the statistic processing LED and	No	No
	(3000-series)	processes the statistics.
417	Statistic processing non-	Turns OFF the statistic processing LED.	No	No
	execution (3000-series)	Statistics are not processed.
