SPSPLCgesteuerte
SPSPLCgesteuerte describes systems and processes controlled by a Speicherprogrammierbare Steuerung (SPS), the German term for a programmable logic controller (PLC). In industrial automation the term denotes equipment and software that perform real-time control of electromechanical processes.
An SPS-PLC gesteuerte control system typically comprises a central processing unit, input and output modules, power
Networking and scalability are achieved through distributed I/O, remote I/O, and fieldbus or industrial Ethernet networks
History and role: PLCs were developed in the 1960s to replace hard-wired relay logic and have become
Advantages include deterministic performance, powerful diagnostics, and compatibility with existing industrial networks. Limitations can include higher
