About using UBIQUITY in combination with Hilscher gateways

The information reported refers to the use of the version 1.54 of the IBH Hilscher.

The NL50-MPI / NT50-MPI gateway must be powered and connected to the network interface of the panel.

The following figure shows the hardware setup.



From the Hilscher web site (http://www.ibhsoftec.com), it is possible to get drivers updates.

Install the driver of the gateway on the PC where you have Control Center

At the end of the setup restart the PC.

Start the Step 7 software and select the PG/PC Interface properties. Create then a “new station”, according to the instruction shown in the following figure.


Give a name to the Station, insert an IP address to be assigned to the gateway, select the profile to use between MPI, Profibus or PPI and select the “IBH Link S7 / IBH Link S7 ++” option.

You may also increase the timeout to higher values in case of remote assistance applications (e.g. 10.000 or 15.000), as shown in the following figure.


Then start UBIQUITY and activate the VPN connection with the device running UBIQUITY Runtime to which the Hilscher gateway is connected.

Highlight the chosen station and press “IBH Link S7”.

From the “Multiple network card detected” dialog select the UBIQUITY Ethernet Adapter, where NL50-MPI/NT50-MPI is located, and confirm.


The network scan operation shall return the connected gateway as available. Select it and click “Settings”.

In case the Hilscher gateway has been never configured before, you will need to assign to it a valid IP address.

Note the IP just assigned is not yet permanent and it will be lost in case of power cycle of the gateway.

From the “Settings” dialog you will need to assign now the complete network configuration of the gateway.


In the MPI/Profibus tab the settings must be the following:

  • Communication speed: Baudrate.

  • Own device Address: MPI/PPI/Profibus address to be assigned to the gateway port. This address node must be unique in the network.

  • Maximum device address: highest node number in the MPI/Profibus/PPI network.

  • Bus Profile: MPI/PPI o Profibus.

Once the settings are completed, you can now save them permanently with the proper command “Save permanently”.
