PLC remote maintenance module
NETLink® PRO Helmholz

The NETLink® PRO for programming, configuring and visualization of S7 PLCs from Siemens is plugged into the CPU of the programmable controller. The connecting cable is an active cable and therefore does not influence the MPI/PROFIBUS. The bus connector is equipped with a programming unit socket to which additional devices can be connected. The NETLink® PRO can optionally be powered from an external 24 V DC power source. At the controller end, the NETLink® PRO via MPI and PROFIBUS allows the full transmission speed of 12 Mbps and 12 simultaneous connections.
Moreover, the new NETLink® PRO features automatic baudrate detection and flexible configuration, such as DHCP and a web interface. The 3 m Ethernet connecting cable (straight) is provided with the NETLink® PRO. At the TCP/IP-end, the NETLink® PRO can be used both in the LAN and in the WAN (for example, via VPN). The MPI/PPI/PROFIBUS is electrically isolated from the external 24 V DC power source and from the Ethernet interface (functional separation).

Furthermore, you can perform diagnostic and configurations with the supplied SHTools software. A free download of the latest SHTools version is available on our download area. Thus, additional functions can be updated at every time on your own.
