Programmable logic controllers

Programmable logic controllers for traditional automation solutions.

At TR-Electronic you will find different PLC variants for specific requirements: SPCP is our slot PLC for integration into higher level control PCs; the @PLC is a modular control for DIN-rail mounting for integration into networked automation environments.

Despite the fact that industrial PCs are becoming ever more powerful there is a requirement to use classic PLC systems as the central control, particularly in conjunction with retrofit tasks. The SPC-P is such a PLC, which is fully integrated into a higher level visualization computer. For simplified visualization and operation the SPC-P communicates with the the host PC via the PCI bus. Standard fieldbuses are offered for peripheral communication. Consequently the SPC-P slot PLC combines the stability of a separate CPU with simplified access to the process image through visualization.

To relieve the higher level control and the fieldbus, we offer a flexible PLC solution for decentralized pre-processing of signals and independent handling of sub-processes in the framework of our modular @ctiveIO fieldbus system with @PLC. @PLC is available for the standard automation bus systems and enables the independent construction of system parts with a standardized programming language (IEC-61131).
