Automatic Program Operation - 69 - FDC MCT-MC
The MC uses “band” type holdback operations. This means the MC will be in hold mode when the loop process
value is above or below the loop set point by the entered holdback limit value during step operation.
6.1.5 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 MC 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.
To program a jump step, select jump for the step type and enter the step number that you want the program to
jump back to along with the total number of times the jump is to be made (by pressing each row in the list). A
cycle count of one indicates that no jump will be made since one cycle is completed upon reaching the jump
step.
