TwinCAT Controller Redundancy: Controller redundancy with standard hardware components
Software-based solution protects plant uptime through redundant control operation
Plant availability plays a crucial role in the process industry in particular, so building redundancy into automation technology designs is vital. This is why Beckhoff expanded its extensive range of solutions in this area to also include a software solution for redundant control operation: TwinCAT Controller Redundancy.
While the robust design of the company’s Industrial PCs alone already ensures a high level of availability, Beckhoff is now expanding its product portfolio to check yet another box with TwinCAT Controller Redundancy (TF1100). This entirely software-based solution allows two standard industrial PCs that both run the same PLC program to operate as redundant controllers in just a few easy steps.
An additional, high-performance network connection between the two controllers provides the necessary synchronization. Standard Ethernet is used here, so no dedicated hardware components are required. With minimal effort, this ensures that only one of the two industrial PCs addresses the fieldbus components at any given time, and that the control programs are executed simultaneously on both computers. This synchronicity is the basic prerequisite for changing the primary industrial PC in the event of a fault without losing any information.
