Designating Data Register as S1
When a data register is designated as source device S1, conversion type and transmit digits must also be assigned. The data
stored in the designated data register is converted and the assigned quantity of digits of the resultant data is transmitted. The
conversion types that are available are: Binary to ASCII, BCD to ASCII, and no conversion.
When repeat is designated, data of data registers as many as the repeat cycles are transmitted, starting with the designated data
register. Repeat cycles can be up to 99.
Conversion Type
The transmit data is converted according to the designated conversion type as described below:
Example: D10 stores 000Ch (12)
(1) Binary to ASCII conversion
(2) BCD to ASCII conversion
(3) No conversion
Transmit Digits (Bytes)
After conversion, the transmit data is taken out in specified digits. Possible digits depend on the selected conversion type.
Example: D10 stores 010Ch (268)
(1) Binary to ASCII conversion, Transmit digits = 2
(2) BCD to ASCII conversion, Transmit digits = 3
(3) No conversion, Transmit digits = 1
