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 Bar Code Reader keeps reading. Execute sequence No.
351 (BCR read stop) to end the sequence.
•
The reception wait time is not set for this sequence.
Precautions for Correct Use
Precautions for Correct Use
Sequences No. 361 and No. 364 (Continuous Data Read with Interrupt) are not supported by the
CS1W-SCU
@@
(-V1) and CJ1W-SCU
@@
(-V1) Serial Communications Units. A protocol macro
syntax error will occur if an attempt is made to execute either sequence with a Serial Communi-
cations Unit.
This sequence clears the log data, confirms BCR connection and sets the BCR functions.
Send Data Word Allocation (3rd Operand of PMCR(260))
The send data word allocation is similar to that of sequence No. 354 (BCR Function Set).
Receive Data Word Allocation (4th Operand of PMCR(260))
None.
This sequence performs the following operations repeatedly: instructs the Bar Code Reader to start
reading and receives the data read by the Bar Code Reader. 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. 352 (Data Read).
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 bar code still keeps reading. Execute sequence No. 351
(BCR Read Stop) to end the sequence.
•
The reception wait time is not set for this sequence.
BCR Initialize (V500) (Sequence No. 362 (Hex 016A))
Continuous Data Read (Scan) (V520) (Sequence No. 363 (Hex 016B))
