Digitalization unfolds its full benefits when an increasing number of different trades are networked with each other. Ideally, you should be able to view plants holistically throughout their entire lifecycle, from planning through construction to commissioning and operation, in order to increase their efficiency in all phases of the lifecycle. This is particularly true for complex plants operating in the process industry, and safety plays an essential role in this context. However, the demand for safe and flexible programming solutions tailored to the customer's specific needs often leads to excessively long development cycle times when, for example, lengthy test processes slow down plant engineering. A modular approach provides a valuable solution to address this concern.
