What's in this program

XICXIOrising-edgeOTLOTUOTETON
  • 9 rungs
  • Uses parallel branches (OR logic)

Instructions used: XIC (examine-if-closed contact (normally open)), XIO (examine-if-open contact (normally closed)), rising-edge (one-shot rising-edge contact), OTL (output latch coil), OTU (output unlatch coil), OTE (output energise coil), TON (on-delay timer).

More example programs

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.
