3Z4L Laser Micrometer Protocol
Receive Data Word Allocation (4th Operand of PMCR(260))
The receive data word allocation is similar to that of sequence No. 434 (Single Run Measurement Start).
Note 1. Since this sequence repeats itself within the sequence, once it is executed, it remains in the execution
state until cancelled.
2. Even if execution is cancelled, the Laser Micrometer still keeps measuring. Execute sequence No.
438 (Measurement Termination) to end the sequence.
3. Sequences No. 413 and No. 437 (Continuous Measurement Start with Interrupt) are not supported
by the CS1W-SCU@@(-V1) and CJ1W-SCU@@(-V1) Serial Communications Units. A protocol syntax
error will occur if an attempt is made to execute either sequence with a Serial Communications Unit.
Do not set an EM bank as the receive storage word for interrupt notification. A protocol syntax error
will occur if an EM banks is set.
Continuous Measurement Termination (4000-series)
(Sequence No. 438 (Hex 01B6))
This sequence terminates continuous measurement.
Send Data Word Allocation (3rd Operand of PMCR(260))
None.
Receive Data Word Allocation (4th Operand of PMCR(260))
For continuous measurement:
For Deflection Measurement
The receive data word allocation is similar to that of sequence No. 434 (Single Run Measurement Start).
Note This sequence may be aborted if it is executed during continuous measurements. Measurements will be
terminated even if the sequence is aborted. The sequence will be aborted if executed when the Laser
Micrometer is sending measurement results. The chances that the sequence will be aborted are higher
if the scheduled data output value is set to a lower value.
Data Request (4000-series) (Sequence No. 439 (Hex 01B7))
This sequence requests display data in the idle measurement status or latch data generated by the measure-
ment command.
Send Data Word Allocation (3rd Operand of PMCR(260))
None.
Receive Data Word Allocation (4th Operand of PMCR(260))
The receive data word allocation is similar to that of sequence No. 434 (Single Run Measurement Start).
Forced Positive Zero (4000-series) (Sequence No. 440 (Hex
01B8))
This sequence sets the forced zero direction to positive (+)
Send Data Word Allocation (3rd Operand of PMCR(260))
None.
Receive Data Word Allocation (4th Operand of PMCR(260))
None.
