3Z4L Laser Micrometer Protocol Appendix N
Deflection Measurement Start (4000-series) (Sequence No. 435
(Hex 01B3))
This sequence starts a deflection measurement.
Send Data Word Allocation (3rd Operand of PMCR(260))
None.
Receive Data Word Allocation (4th Operand of PMCR(260))
None.
Note 1. The deflection measurement keeps measuring until sequence No. 438 (Measurement Termination)
is executed.
2. This sequence will be processed the same as sequence No. 411 Zero run measurement start for
5000-series Laser Micrometers.
Continuous Measurement Start (Scan) (4000-series)
(Sequence No. 436 (Hex 01B4))
This sequence starts a continuous measurement. The scan notification method is used for the receive data.
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).
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.
Continuous Measurement Start (Interrupt) (4000-series)
(Sequence No. 437 (Hex 01B5))
This sequence starts a continuous measurement. The interrupt notification method is used for the receive data
and the interrupt No. is 101.
Send Data Word Allocation (3rd Operand of PMCR(260))
None.
