6.1.5.2 Wait For Set Point
When the wait for condition is selected for one or more inputs, an additional entry for the wait set point (Wait
SP) will be provided at the bottom of the hold selection list. This set point is common for all inputs chosen to
wait for.
The set point entry is critical in order for the step to operate correctly. During the wait state, each selected loop
and/or monitor input must arrive at or cross the wait set point in order for the program to resume operation.
Thus, the previous step must ensure that all selected process values will be moving towards the target wait set
point prior to the step with the wait selections beginning. If all selected loops and/or monitors do not cross the
wait set point after the wait step has started, the program will pause indefinitely on the step until the user takes
action.
6.1.6 Setting Jump Steps
This feature allows the program to jump back to a previous step in order to repeat certain sections of a program.
When a jump step is entered, the program will jump to the specified
“jump step” rather than continuing on to
the next step in the program. After all of the programmed jump cycles have been completed, the program will
then continue to the following step without making any further jumps.
NOTE: The MCTB has the ability to do nested looping, i.e., allowing multiple jump steps to be programmed
throughout a program in which one jump cycle is repeated within another jump cycle. The program
Status screen will display the current cycle count; however, this is for the outer most jump step. If
nested jump loops are programmed, the cycle count of the inner jump loops is not displayed.
