Appendix
22. Waiting for Multiple Inputs
Description
The actuator waits for one of several different inputs, and proceeds to an applicable process when a given
input is received.
Point
With a WTON command, the actuator cannot perform any process unless one of the specified inputs is
received. In other words, the actuator cannot wait for multiple inputs.
Example of Use
Inputs 10 and 11 are monitored and when an input is received from either of the two (OR gate), the
actuator will proceed to the next step.
As shown in the sample, the actuator can be made to wait for input without using a WTON command. This
approach can also be used when multiple input conditions must be combined.
