What's in this program

XICrising-edgeCMPFRDCTUOTE
  • 3 rungs
  • Uses a compare instruction

Instructions used: XIC (examine-if-closed contact (normally open)), rising-edge (one-shot rising-edge contact), CMP (compare instruction), FRD, CTU (count-up counter), OTE (output energise coil).

Start/Stop motor with seal-in

The classic latching start/stop circuit. A momentary start button energises the motor, a parallel branch off the motor output seals the rung in, and a normally-closed stop button drops it out.

On-delay fan start (TON)

A run command starts an on-delay timer; once the preset elapses, the fan output turns on. A textbook TON example showing how the Done bit gates a downstream coil.

Batch counter with compare

Each part pulse increments a count-up counter; a compare instruction watches the accumulator and fires a Batch Complete output when it reaches the target. Shows CTU plus a CMP against a constant.
