Function
When the input is ON, data block transfer is performed between the source which is indirectly
designated by A and A+1 and the destination which is indirectly designated by C and C+1. The
transfer size (number of words) is designated by B.
The transfer size is 1 to 256 words. (except for writing into EEPROM)
Data transfer between the following objects are available.
•
CPU register (RW or D)
↔
EEPROM (D register)
•
CPU register (RW or D)
↔
T1S RS-485 port (T1S only)
