Outline
In programs using step ladder instructions, a state relay State S is assigned to each process based on
machine operations, and input condition and output control are programmed as sequences connected to the
state output.
machine operations, and input condition and output control are programmed as sequences connected to the
state output.
STL instruction for step ladder programs is expressed as follows in each language.
1. Format and operation, execution form
2. Set data
3. Applicable devices
4. Caution
Refer to the cautions in the items below for expressing step ladders in a structured project (Structured ladder/
