Helmholz 700-881-MPI21 Gateways NETLinkŪ


NETLinkŪ PRO PoE, PROFIBUS-Ethernet-Gateway, PoE operating voltage: 48V nach IEEE 802.3af/at, PoE power class: Class 1 (0.44 to 3.84 Watt), Communication interface: Ethernet 10 Base-T 100 Base-TX 10/100 Mbit/s autom. detection; Protocol: FDL, RFC 1006, MPI/PPI/PROFIBUS-Interface: RS485 isolated; max. 12 Mbit/s autom. detection; SUB-D plug, 9 pol. with PG-Interface and Repeater


Product Description

The devices of the NETLinkŪ 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 the diagnostic software SHTools to, for example, automatically perform firmware updates.

The latest version is available for download. Link to Helmholz Downloadpage

It draws its supply voltage through the CPU of the automation device, or optionally via externally supplied DC 24 V, or a CAT5 network cable using a PoE power supply unit.

The NETLinkŪ PRO PoE enables the implementation of TCP/IP on the MPI/PPI/PROFIBUS with up to 32 simultaneously open connection channels.

With the switchable single-master operation, passive bus participants can be addressed.

The integration of SCADA, HMI, and OPC applications is possible via the widely used ISO on TCP (RFC 1006) protocol.

The applications are automatically detected and forwarded by the NETLinkŪ PRO PoE.
