Chapter 8 Programming Examples
Application of STG-JMP instruction
■ Enabling double coil
When start SW 0000 is pressed, output relay 0500 turns ON for 1 s, then output
relays 0500 and 0501 turn ON for 2 s, and then output relays 0500, 0501, and 0502
turn ON for 3 s. The above sequence repeats.

Coding
The double coil operates normally through different STG instructions. If
different STG instructions turn ON simultaneously, the latter programmed
instruction has the priority.
■ Conditional branching
When input relay 0000 (start SW) turns ON, output relay 0500 turns ON. Then, as
programmed for conditional branching, output 0501 turns ON for 1 s when 0001
turns ON or 0502 turns ON for 2 s when 0002 turns ON. After either one of the
processes is completed, the program returns to the conditional branching and
repeats the same steps.
