Omron CQM1H-SCB41 operation manual Send with No Conversion and with Response Sequence No

CompoWay/F Master Protocol Appendix B

2.When hexadecimal data is converted to ASCII data, data is sent starting from the send data word with the largest offset. This is done because ladder programming handles data in 4-byte units.

Send data words

1 2 3 4

5 6 7 8

Send frame

“56” “78” “12” “34”

Receive Data Word Allocation (3rd Operand of PMCR(260))

None. (Specify a dummy value for the operand, such as #0000.)

Send with No Conversion and with Response (Sequence No. 602)

This sequence sends the specified data beginning with the command code to the specified Unit. The response is stored starting at the specified word. No conversions are performed on the send and receive data.
