3Z4L Laser Micrometer Protocol
Continuous Measurement Start (Scan) (3000-series)
(Sequence No. 412 (Hex 019C))
A continuous measurement is started. 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. 410 (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.
414 (Measurement Termination) to end the sequence.
Continuous Measurement Start (Interrupt) (3000-series)
(Sequence No. 413 (Hex 019D))
A continuous measurement is started. 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.
Receive Data Word Allocation (4th Operand of PMCR(260))
The receive data word allocation is similar to that of sequence No. 410 (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.
414 (Measurement Termination) to end the sequence.
3. Sequences No. 413 and No. 437 (Continuous Measurement Start with Interrupt) not supported by the
CS1W-SCU21 and CJ1W-SCU41 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.
Measurement Termination (3000-series) (Sequence No. 414 (Hex
019E))
This sequence terminates a continuous measurement.
Send Data Word Allocation (3rd Operand of PMCR(260))
None.
Receive Data Word Allocation (4th Operand of PMCR(260))
For continuous measurement: Not available
For Zero Run Measurement
The receive data word allocation is similar to that of sequence No. 410 (Single Run Measurement Start).
Note This sequence may be aborted 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.
