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.
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).
Additional Information
• Since this sequence repeats itself within the sequence, once it is executed, it remains in the
execution state until cancelled.
• Even if execution is cancelled, the Laser Micrometer still keeps measuring. Execute sequence
No. 438 (Measurement Termination) to end the sequence.
Precautions for Correct Use Precautions for Correct Use
• Sequences No. 413 and No. 437 (Continuous Measurement Start with Interrupt) are not sup-
ported by the CS1W-SCU

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 bank is set.
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: None.
For Deflection Measurement:
The receive data word allocation is similar to that of sequence No. 434 (Single Run Measurement
Start).
Additional Information
This sequence may be aborted if it is executed during continuous measurements. Measure-
ments will be terminated even if the sequence is aborted. This occurs because this sequence
was executed while the Laser Micrometer was 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.
