JumploopsThe Four JUMPLOOP TypesThe Series 922 gives you the capability to perform four basic jumploop types inyour programming. The backward jump, forward jump, nested loops, andintertwining loops. These are only definitions of the four loops. The Series922 has very few rules concerning loops in your program.Backward JumpThe Backward jump is the most common jump. A backward jump will forceyou to a step already performed. The Jump Step (JS) must be less than thecurrent step. You cannot JUMPLOOP to the step that you are on.Step 2 SETPOINTStep 3 SETPOINTStep 4 SETPOINTStep 5 JUMPLOOP JS - 02 JC - 01Step 6 STOPThe steps in sequence will be: 2, 3, 4, 5, 2, 3, 4, 5, 6.Your Jump Count (JC) can be anything from 0 - 100. If you enter 0, this will bean infinite loop and will never progress to Step 6.Forward JumpThe next loop type is a Forward jump. By definition you can jump forward.The Jump Step must be greater than this step.Step 1 SETPOINTStep 2 SETPOINTStep 3 JUMPLOOP JS - 05 JC - 01Step 4 SETPOINTStep 5 STOPThe steps in sequence will be: 1, 2, 3, 5.40 WATLOW Series 922 User's Manual How To Program the Series 922, Chapter 6
