A PLC simulator is a software tool that mimics the behavior of a real PLC, allowing users to test, train, and troubleshoot PLC programs in a virtual environment. PLC simulators are designed to replicate the functionality of actual PLCs, including inputs, outputs, and programming logic. They are commonly used in industries such as manufacturing, oil and gas, and automotive, where PLC systems are widely used.
