Type
The Type field determines the function to be performed. The three
options are:
• Wait for Input On
• Wait for Input Off
• If Input
Require OFF to ON Transition
When you select Wait for Input ON, you enable the Require OFF to ON
transition field.
If you select Require OFF to ON Transition, the program pauses until the
selected input turns off and then on again. This is the same as using two
Input blocks with the same parameter settings, except that:
• the first Input block would be set to Wait for Input OFF
• the second Input block would be set to Wait for Input ON
• the Require OFF to ON Transition would not be selected in either
Input block.
Require ON to OFF Transition
When you select Wait for Input OFF, you enable the Require ON to OFF
Transition field.
If you select Require ON to OFF Transition, the program pauses until the
selected input turns on and then off again. This is the same as using two
Input blocks with the same parameter settings, except that:
• the first Input block would be set to Wait for Input ON
• the second Input block would be set to Wait for Input OFF
• the Require ON to OFF Transition would not be selected in either
