Abstract

The preferred embodiments described below include methods, systems and computer readable media for generating programmable logic controller (PLC) code based on a connectivity model in a multidisciplinary engineering system. The connectivity model provides interfaces 613 and 617 and connections 619 between various aspects of the multidisciplinary engineering system to provide engineering data, code scripts, executables, calls and other information that is used to generate PLC code. Code generation rules 621 are employed utilizing the engineering data, code scripts, executables, calls and other information received using the connectivity model to generate PLC code.
