Operands:

S: English letters to be converted into ASCII code D: Device for storing ASCII code

Explanation:

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.

If PLC is connected to a 7-segment display while executing ASC instruction, the error

message can be displayed by English letters

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 converted from
