An engineering system for orchestration of an industrial plant includes: a modular plant to be orchestrated including at least one processor from a topology having: a process orchestration layer, and a plurality of modules. A portion of the plurality of modules are formed as at least one combined module. Each combined module of the at least one combined module has at least two different modules of the portion of the plurality of modules. The process orchestration layer controls the plurality of modules. The control by the process orchestration layer includes in-direct control of the portion of the plurality of modules via control of the at least one combined module.
