NETLink®
PRO Compact
The devices of the NETLink family serve the purpose of programming, configuring, and visualizing S7 PLCs.
In general, connection to each MPI/PROFIBUS terminal of the bus system or directly at the interfaces of active and passive participants is also possible. The PG socket integrated in the connector housing allows connection of additional devices.
The integrated web interface offers parameterization, diagnostic, and security features, and for functional enhancements, the user can use our free diagnostic software SHTools to, for example, automatically perform firmware updates. The latest version is available for download.
The NETLink PRO Compact is a communications processor in the plug format for programming, visualization, and remote maintenance. It combines flexibility and a compact design. Power is supplied to the NETL ink® either through the CPU of the automation device or externally with DC 24 V as an option. The network connection can be used with any standard Cat-5 cable, making cable lengths up to 100 meters feasible without additional components.
