Function

When the input is ON, data block transfer is per formed bet ween the source which is indirectly

designated by

A

and

A+1

and the destination which is indirectly designat ed by

C

and

C+1

. The

transfer size (number of words) is designated by

B

.

The tr ansfer size is 1 to 256 words. (except for writing into EEPROM)

Data transfer between the following objects are available.

· CPU regist er (RW or D) « EEPROM (D register )

· CPU regist er (RW or D) « T1S RS-485 port ( T1S only)
