Method and system for testing software for industrial machine

A method for testing software for an industrial machine, the method comprising the steps of:

• creating a coded program comprising a diagram through which the industrial machine having a programmable logic controller is driven, wherein the diagram includes production processes to be sequentially performed by the industrial machine:
• compiling the coded program using a compiler into a compiled program comprising an instruction with which the industrial machine is driven;
• downloading the compiled program onto a simulator for implementing a programming interface provided by the industrial machine;
• executing the compiled program in the simulator;
• loading the compiled program into a testing tool;
• analyzing the compiled program using the testing tool before the compiled program is embedded in the programmable logic controller of the industrial machine;
• generating a first data by the testing tool for testing the compiled program;
• transmitting the first test data from the testing tool to the simulator having the downloaded compiled program;
• and
• analyzing the first test data using the simulator for errors;
• wherein if an error is not detected in the first test data using the simulator, the compiled program is embedded into a programmable logic controller associated with the industrial machine.
