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.
Top Free PLC Simulator Software
- Do-more® Designer
This software creates a virtual PLC. The logic can be tested with this virtual PLC. This software gives the flexibility to test the ladder logic without a PLC.
The simulator supports discrete and analog Input/ output simulation.
PID function can be simulated. Use the Simulator coupled with the Trend View for outstanding visibility of PID processes.

- PSIM PLC Simulator
PSIM PLC simulator is used for creating and simulating PLC programs using Allen Bradly PLC-2 family instructions.
PSIM emulates scanning sequence of a PLC. When it is in run mode it scans the user program and updates I/O just as would occur in a real PLC.
PSIM contains animated simulation.
Platform - Windows
