LON
LON

LONs (Local Operation Networks) are primarily used in building automation and were designed for distributed industrial applications with non-time-critical requirements. Every participant in this system has its own intelligence, which means that a superimposed open-loop control is often not required. Lenze LONs modules operate with the widely-used standard FTT transmission.
