An year ago i made a plc (programmable logic controller) using microchip pic microcontroller. Its a 16 bit digital input and output programmable logic controller. Plc programming is done using a standard ladder logic language. The software that is used for plc programming and ladder logic design is an open source compiler written by Jonathan Westhues…
The goal of fail-safe circuit design is to make a control system as tolerant as possible to likely wiring or component failures.
PLC Data Comparison Instructions like “less than”, “greater than”, “less than or equal to”, “greater than or equal to”, “equal to”, and “not equal to” .
Use the instructions (set, reset) with the timer (SM0.4) to turn an output on/off after several pulses from the SM0.4 timer.
A timer is a PLC instruction measuring the amount of time elapsed following an event. Types of Timer instructions : on-delay timers and off-delay timers.
