A Standard System Protocol
R-74
CJ-series Serial Communications Units Operation Manual for NJ-series CPU Unit(W494)
This sequence confirms whether the Bar Code Reader is connected correctly or not.
Send Data Word Allocation (3rd Operand of PMCR(260))
None.
Receive Data Word Allocation (4th Operand of PMCR(260))
None.
This sequence clears the log data.
Send Data Word Allocation (3rd Operand of PMCR(260))
None.
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))
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 Reader still keeps reading. Execute sequence
No. 351 (BCR read stop) to end the sequence.
•
The reception wait time is not set for this sequence.
This sequence performs the following operations repeatedly: Instruct the Bar Code Reader to start
reading and receives the data read by the Bar Code Reader. The interrupt notification method is used
for the receive data and the interrupt No. is 100.
Send Data Word Allocation (3rd Operand of PMCR(260))
None.
Receive Data Word Allocation (4th Operand of PMCR(260))
The receive data word allocation similar to that of sequence No. 352 (data read).
BCR Connection Confirmation (V500) (Sequence No. 358 (Hex 0166))
Log Data Clear (V500) (Sequence No. 359 (Hex 0167))
Continuous Data Read (Scan) (V500) (Sequence No. 360 (Hex 0168))
Continuous Data Read (Interrupt) (V500) (Sequence No. 361 (Hex
0169))
