Operands:
S: English letters to be converted into ASCII code (A~Z or a~z only) D: Device for storing ASCII
code
Explanation:
1. The ASC instruction converts 8 English letters stored in S and save the converted ASCII code
in D. The value in S can be input by WPLSoft or ISPSoft.
2. If PLC is connected to a 7-segment display while executing ASC instruction, the error message
can be displayed by English letters
3. Flag: M1161 (8/16 bit mode switch)
Program Example:
When X0 = ON, A~H is converted to ASCII code and stored in D0~D3.

When M1161 = ON, every ASCII code convert

the letters will occupy the lower 8 bits (b7 ~ b0) of a
register and the upper 8 bits are invalid (filled by 0),
i.e. one register stores a letter
