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 (T 1S only)
