Installation: TwinCAT runtime (XAR)
Preconditions for Proper Real-Time Behavior For a reliable, optimized and performant realtime behavior, a completely aligned system design (hardware, BIOS, OS, drivers, realtime-runtime) is mandatory. Each single component of the control system has to be checked and optimized for this type of application - that is the one and only way for an optimal, reliable and performant realtime behavior. Beckhoff IPCs are optimized in each detail for this type of operation. There is no guarantee for proper, reliable realtime behavior on third-party PCs. |
