Selection Notes

The 2048 PowerTags license lifts the WinCC Runtime Advanced tag ceiling fourfold over the 512-tag version, which matters once the application spans multiple HMI screens or a wider set of monitored I/O points. Choose this variant over the 512 PowerTags version when the project's tag count is already near or past 512, since upgrading a license later costs more than buying the larger one up front. The Failsafe Software Controller CPU 1505SP F V2x and WinCC Runtime Advanced V17 share the same Intel Atom E3940 processor and 8 GB RAM as the smaller-license unit, so the extra tag headroom comes at identical hardware cost and the same 55 W active power draw.
