Operands:

S: Device for storing ASCII code (occupies 4 consecutive devices) D: External ASCII code output

points (occupies 10 consecutive devices)

Explanations:

1. This instruction will output the ASCII codes in the 4 registers starting from S through output

points started from D.

2. D

~ D

map to source data (ASCII code) directly in order, D

is the scan signal and D

is the

execution flag.

3. This instruction can only be used twice in the program.

4. Flags: M1029 (PR execution completed); M1027 (PR output mode selection).

Program Example 1:

1. Use API 76 ASC to convert A ~ H into ASCII codes and store them in D0 ~ D3. After this, use

this instruction to output the codes in sequence.

2. When M1027 = OFF and X20 = ON, the instruction will designate Y20 (lowest bit) ~ Y27

(highest bit) as the output points and Y30 as scan signals, Y31 as execution flag. In this mode,

users can execute an output for 8 letters in sequence..

3. If X20 turns from ON → OFF during the execution of the instruction, the data output will be

interrupted, and all the output points will be OFF. When X20 = ON again, the data output will

start from the first letter again.
