Set the DM address into which ASCII code is to be written as follows.
■ Binary
A binary value be converted is input to 16 high-order bits and 16 low-order bits in
data memory addresses separately.
■ Decimal position
Specifies the decimal position written in the ASCII string. If 0, no decimal point is
specified.
After conversion, the ASCII code for decimal point (2EH) is stored in the specified
position counting from the top of the ASCII string. For example, when the binary
value is 1234 and decimal position is 2, the specified value becomes 1.234, which is
31H 2EH 32H 33H 34H in ASCII.
■ Number of bytes in ASCII string
Specify the total number of bytes, including binary digits, +/- sign, and decimal point.
For example, when a value is -12.34, "6" is written here.
■ Signs
Specify the +/- sign to be appended to the converted value (from binary to ASCII).
The +/- sign is stored in the first DM address of the ASCII string.
• 0: No sign
No +/- sign is appended to the ASCII-converted value. "0" can be specified when the
binary value is positive. If "0" is specified when a binary value is a 2’s complement,
the binary is treated as a positive value.
• 1: - sign
Converts a binary value by giving -(2DH) when the binary value is a 2’s complement.
Adds no sign to a positive binary.
• 2: ± sign
Converts a positive binary by giving +(2BH) and a negative binary (2’s complement)
by giving -(2DH).
The ASCII-converted value is loaded to data memory addresses as follows.
The number of DM addresses used is the value specified as the number of bytes in
the ASCII string.
