FUN 236 XFER Expanded data transfer
Expression
Input −[ A XFER B → C ]− Output
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)
