Designating Data Register as S1
When a data register is designated as source device S1, receive digits and conversion type must also be designated. The received
data is divided into blocks of specified receive digits, converted in a specified conversion type, and stored to the designated data
registers. Conversion types are available in ASCII to Binary, ASCII to BCD, and no conversion.
When repeat is designated, received data is divided, converted, and stored into data registers as many as the repeat cycles,
starting with the designated data register. Repeat cycles can be up to 99.
When a data register is designated as source device S1, a delimiter can be included in the data register designation to end
receiving communication.
Receive Digits
The received data is divided into blocks of specified receive digits before conversion as described below:
Example: Received data of 6 bytes are divided in different receive digits. (Repeat is also designated.)
Conversion Type
The data block of the specified receive digits is then converted according to the designated conversion type as described below:
Example: Received data has been divided into a 2-digit block.
(1) ASCII to Binary conversion
(2) ASCII to BCD conversion
(3) No conversion
