Darwin. Evolution in the control cabinet.

The true meaning of evolution is development step by step. The complete redesign of the control cabinet can thus only be achieved in single evolutionary stages. Starting with the switching devices, the PLC, the drives and the visualisation have to be included in this project. A process which, due to its depth and scope, can only be implemented by a leading manufacturer like Moeller.

The diagrams show the development steps already completed as well as future developments.

Yesterday Every sensor and actuator is wired separately to the inputs and outputs of the central PLC. Result: High wiring requirements, massive, expensive control cabinets and complex commissioning. Today The sensors and actuators are wired on remote pre-processing stations and connected from there to the central controller via a fieldbus. Result: Reduced wiring thanks to remote I/Os and fieldbus technology. The control system is distributed over several small control cabinets positioned along the machine. High configuration requirement. Today with SmartWire Motor starters and PLC are connected directly. The rest of the wiring is carried out according to current practice. Result: The wiring requirement for contactors and motor starters is considerably reduced as well as the number of remote I/Os, including terminals and connectors. No wiring faults. The I/O level is located directly at the contactor. Tomorrow with Connect The control circuit wiring between the controller and the switching devices is completely replaced by easyConnect. Result: All the devices connected with easyConnect function as local or remote inputs/outputs of the easyControl. The system is configured automatically. Wiring faults are prevented.
