Figure 8-15 Digital Input Functions
Run Program: When selected, the input will start the currently loaded program at step one.
If a program is currently running, no action will occur. This is a ‘single-shot’
activation in which the input must make the required transition state in order
to activate the function.
If a program is currently operating but it is in hold, the input will put
the program into the run state.
Hold Program:
When selected, the input will put a running program into the hold state. If a
program is not currently running, no action will occur. This is a ‘single-shot’
activation in which the input must make the required transition state in order
to activate the function.
Continue Program:
When selected, the input will put a program that is in hold, into the run state.
If a program is not active or the program is not currently in hold, no action will
occur. This is a ‘single-shot’ activation in which the input must make the
required transition state in order to activate the function.
End Program: When selected, the input will turn the program off. This will also turn off all
system events. If a program is not running, no action will occur and event
status will not be affected. This is a ‘single-shot’ activation in which the
input must make the required transition state in order to activate the function.
Wait Input:
When selected, the input acts as a trigger input for a ramp/soak program wait
for digital function. The input can then be selected in the program to pause
the current step until the input changes state according to the transition mode
selection.
See Section 4.1.5, Using Wait For.
The program must be in the “wait” state prior to the input making the
desired transition. If the input makes the transition prior to the
program entering the wait for input state, the program will not
continue.
