Integrating the functionality of numerous components into a single PLC brings two main advantages: cost savings, as only one device is required instead of multiple modules, making project planning and programming easier; efficiency gains, as the overall workload (e.g. in logistics, assembly and testing) is significantly reduced compared to modular product solutions; and the use of a single, compact PLC as the central heart and mind of the entire system. At the same time, the use of a compact PLC as the central heart and brain of the entire system ensures increased functional reliability through faster data communication.
