Toshiba PROSEC T3H user manual CPU register ↔ S20/S20LP scan memory

2. Expanded Functions

CPU register ↔ S20/S20LP scan memory

Example:

Source designation			Transfer size		Destination designation
RW000	H00	H01	RW002	00010	RW010	H01	H10
RW001	00000				RW011	00000
W0000 (CPU register)			10 words transfer		Channel 1 S20/S20LP

scan memory address 00000

When R0000 is ON, 10 words data starting with W0000 is transferred to scan memory address 00000 and after of channel 1 S20/S20LP.

Remarks:

•When writing data into S20/S20LP scan memory, confirm that the address range is S20/S20LP’s data send block.

•If S20/S20LP scan memory is accessed only by this XFER instruction, the network assignment, i.e. “LINK” or “GLOBAL” setting, is not necessary.

•When S20 is designated as source, the status flag (scan healthy map) for the read-out data is stored in operand B+1 and after. (Status flag is not created for S20LP)

For example, when 99 words data is read from S20 with using RW030 as transfer size designation, RW031 to RW037 (7 words) are used to store the scan healthy map.

RW030								99
RW031	F			C				8				4				0
	16	15	14	13	12	11	10	9	8	7	6	5	4	3	2	1
RW032	32	31	30	29	28	27	26	25	24	23	22	21	20	29	18	17
RW036
	96	95	94	93	92	91	90	89	88	87	86	85	84	83	82	81
RW037														99	98	97

0 is stored in the excess bits
