Difference between PLC and Microcontroller? PLC PLC

The difference between a PLC ladder program and relay ladder rungs is the continuity. In an electrical rung diagram, there is an electrical continuity only when the current flows from left power rail to right power rail. 2 Fig (a), shows electrical continuity when SW1 is closed, as the current flows from L-1 to L-2 energizing the load. Even though PLC ladder logic was modeled after the

Difference between PLC and Microcontroller? PLC PLC

Use with a programmable logic controller (PLC). When selecting a sensor to be used with a PLC, it is very important that the sensor matches the type of PLC input card to be used. Two types of input cards exist, those that 'sink' current (also known as positive logic) and those that 'source' current (also known as negative logic).
