Ethernet - PROFIBUS fieldbus gateway
NETLink® Switch Helmholz

The NETLink® Switch is an Ethernet Gateway with integrated 4 port store-and-forward switch for programming on S7-200*, S7-300* and S7-400* PLCs. It is intended for mounting on a DIN rail bracket. Either it is integrated in the bus with a PROFIBUS connector or plugged directly with an active drop cable onto the MPI/PPI or PROFIBUS interface of a bus subscriber.
The NETL ink® Switch is powered from an external 24 V DC power source. At the controller end, the NETL ink® Switch permits the full transmission speed of 12 Mbps with maximum 32 simultaneous connections via MPI or PROFIBUS.
The baud rate is detected automatically and a Single-Master function enables communication to passive participants. The supplied driver automatically embeds in the S7 Engineering Tools. Furthermore, NETL ink® Switch supports widely used ISO on TCP (RFC 1006) protocol. Therefore, the integration of SCADA, HMI and OPC applications can be realized very easily. The integrated web interface provides even more parameterization- and security functions. Besides the gateway function the integrated 4 port 10Base-T/100Base-TX switch can be used to integrate additional Ethernet subscribers.
Furthermore, you can perform diagnostic and cinfigurations 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.
