Omron CQM1H-SCB41 Flags, First Receive Data, Storage Word D, PMCR-- Operation, Name Address

	Using Protocol Macros	Section 5-7
		The number of send words in S+1 and the following words is stored in S. The
		setting range is 0001 to 0129 (4 digits BCD). S is also included in the number of
		words.
	Note When there is no send data, set S to #0000. If any other constant or a word ad-
		dress is set, an error will occur, the Error Flag (SR 25503) will turn ON, and
		PMCR(––) will not be executed.
First Receive Data		D specifies the first word of the area used to store the receive data.

Storage Word (D)

If a word address is specified for D and a response is requested, the data through the highest location received in the reception buffer will be stored in memory starting at D+1. The number of words that was stored starting at D+1 will be stored in D. D is included in the number of words.

	The number of words of receive data in D+1 and the following words is stored in
	D. The range is 0001 to 0129 (4 digits BCD). D is also included in the number of
	words.
	Note When there is no receive data, set D to to a dummy word address. If any constant
	is set, an error will occur, the Error Flag (SR 25503) will turn ON, and PMCR(––)
	will not be executed.
PMCR(––) Operation	When PMCR(––) is executed, the communications sequence specified in bits
	00 to 11 of C is executed for the port specified in bits 12 to 15 of C (port 1 or 2).
	If an operand is specified as a variable in the send message, data starting in S+1
	for the number of words specified in S is used as the send data. If an operand is
	specified as a variable in the receive message, data will be received in words
	starting from D+1 and the number of words of received data will be automatically
	stored in D.
