Omron CQM1H-SCB41 Polling Auto-write Hexadecimal/8 Sequence No, Data Check Sequence No

V600/V620 ID Controller Protocol Appendix M

Note 1. Execute Sequence No. 536 before executing Sequence No. 537. 2. Retry processing is not performed for this sequence.

Polling Auto-write (Hexadecimal/8) (Sequence No. 538)

This sequence is used when the number of Heads to be written to the Carrier is 8.

Send Data Word Allocation (2nd Operand of PMCR)

The send data word allocation is similar to that of Sequence No. 525 (Write (Hexadecimal/8)).

Receive Data Word Allocation (3rd Operand of PMCR)

The receive data word allocation is similar to that of Sequence No. 525 (Write (Hexadecimal/8)).

Note 1. Execute Sequence No. 545 (Polling Auto-write Command Processing Cancel) to cancel the polling auto-write.

2. Retry processing is not performed for this sequence.

Polling Auto-write Subcommand (Hexadecimal/8) (Sequence No. 539)

This sequence is used when the number of Heads to be written to the Carrier is 8. Up to 10 digits of data can be written for each Read/Write Head.

Send Data Word Allocation (2nd Operand of PMCR)

The send data word allocation is similar to that of Sequence No. 525 (Write (Hexadecimal/8)). However, the lead- ing address No., number of write, and write data are not used and become undefined.

Receive Data Word Allocation (3rd Operand of PMCR)

None.

Note 1. Execute Sequence No. 538 before executing Sequence No. 539. 2. Retry processing is not performed for this sequence.

Data Check (Sequence No. 540)

This sequence writes and verifies the CRC code for check blocks designated by the user.
