Application Examples 8-15
Application Example Program
Shown below is an excerpt from the user program. When the switch is
closed, bulbs 1 and 2 turn on and the decimal value 5555 is moved to
analog output 1 and is converted to an analog signal.
The following is another representation of what is discussed above.
This application consists of a PLC-5/40 processor controlling local and
remote I/O.

(1) Input bits 16–31 must be converted to 0–15 by subtracting 16. Therefore, Input bit 17 is converted to 1.
(2) Input and Output bits 0–7 must be converted to 8–15 by adding 8. Therefore, Input bit 12 is converted to 4.
