Omron CQM1H-SCB41 operation manual Broadcast with Ascii Conversion, No Response Sequence No

CompoWay/F Master Protocol Appendix B

The 2nd and 3rd operands of the PMCR(260) instruction are specified as follows.

Send Data Word Allocation (2nd Operand of PMCR(260))

Offset	Contents (data format)		Data
+0	Number of send data words		0007
	(4 digits BCD)
+1	(Undefined)	Node No. (2 digits	0000 Hex
		BCD)
+2	MRC	SRC	0101 Hex
	(2 digits Hex)	(2 digits Hex)
+3	Number of send bytes (4 digits BCD)		0012 (BCD)
+4	Send data (12 digits Hex)		C000 Hex
+5			0000 Hex
+6			0001 Hex

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

Offset	Contents (data format)	Data
+0	Number of receive data words	EX is stored at reception (0004)
	(4 digits BCD)
+1	Response code (4 digits Hex)	The response code will be stored in
		hexadecimal form.
		The normal end response code is 0000.
+2	Receive data (8 digits Hex)	The 4 bytes of read data.
+3

Broadcast with ASCII Conversion, No Response (Sequence No. 601)

This sequence converts the specified data beginning with the command code to ASCII and broadcasts it. No re- sponses are received.

Send Data Word Allocation (2nd Operand of PMCR(260))

First word of	+0	Number of send data words
send data
	+1		(Undefined)
	+2	MRC		SRC
	+3	Number of send bytes
	+4		Send data

Offset	Contents (data format)		Data
+0	Number of send data words		0005 to 0128
	(4 digits BCD)
+1	(Undefined)		---
+2	MRC	SRC	Set the command code for the required
	(2 digits Hex)	(2 digits Hex)	service
+3	Number of send bytes (4 digits BCD)		Number of data bytes from the next byte
			after the command code until the byte just
			before the ETX.
			0 to 984 decimal
+4	Send data (4-digit Hex)		The data specified in hexadecimal here will
on			be converted to ASCII and the number of
			bytes specified in S+3 will be sent.

Note 1. Set the number of send bytes to twice the number of bytes in memory. This is necessary because the data is converted to ASCII data before being sent.
