Top Free PLC Simulator Software



What is PLC Simulator?

PLC simulators are used for simulating PLC operation on a personal computer or on a mobile phone.

Ladder logic program can be simulated with the help of a PLC simulator.

A physical PLC is not required to test the ladder logic program.

PLC simulator allows programmer to force input and output signal and test the ladder logic diagrams.

PLC programmer can test and debug the program before installation into its operating environment.

What are the uses of PLC Simulator ?

For testing ladder logic. PLC simulator helps to debug a PLC program.

For training PLC programmers.
