Part 2 Programs
21. Waiting Multiple Inputs
Description
The controller waits for multiple different inputs and performs processing upon reception of any of these
inputs.
Point
A WTON command permits processing only when the specified input is received. The controller cannot
wait for multiple inputs.
Example of Use
Inputs 10 and 11 are monitored, and the actuator will proceed to the next step when either input is
received (OR logic).
Program a
Program b
As shown in the sample, the controller waits for input without using a WTON command.
This method can also be used when multiple input conditions must be combined.
Input 10
Input 11
Next processing
* Both programs a and b perform the same processing.
