Abstract

A method of automatically generating and verifying programmable logic controller (PLC) code. The method includes the steps of constructing a neutral control model file, determining whether the neutral control model file is correct, generating PLC code if the neutral control model file is correct, verifying whether the PLC code is correct, and using the PLC code to build a tool.
