PROFIBUS Master Single Channel USB Interface Card



Universal PROFIBUS Interface with USB High Speed Port

High performance, single channel PROFIBUS USB interface for a wide variety of tasks from network configuration, device parameterization and PLC programming to plant maintenance and production data acquisition.

  • Rugged Metal Housing for Everyday Use in the Field
  • Active Bus Connection Cable for Reduced Disturbances
  • Easy Integration via API, OPC, DTM or STEP7 Drivers

Flexible PROFIBUS Interface for Mobile Applications

Quickly connected to a notebook and ideal for flexible use on different PCs, PROFIusb connects applications on the PC with a PROFIBUS network. As a DP Master Class 2, PROFIusb provides the basis for typical parameterization and maintenance tools. PROFIusb can also perform active control functions as a DP Master Class 1 or via the lowest protocol level (FDL).

Easy, Convenient and Reliable

PROFIusb is very simple and easy to use. To install this compact, rugged device all you do is plug it into the USB port on your PC. The interface runs entirely on USB power so that no external power supply is needed. Thanks to an active electronic coupler inside the bus cable, the connected PROFIBUS segment is not extended. This reliably eliminates disturbances caused by reflections.

Rapidly Integrated Using the Right Software Interface

Using the PROFIBUS API, PROFIusb can be operated directly from the application. Commented sample programs show how this is done. A matching Softing OPC Server, which is available as an optional standard interface, quickly and easily connects any application that has an integrated OPC client. Typical applications include visualization, SCADA or MES systems. FDT compliant parameterization tools use the PROFIdtm Communication DTM from Softing as a link to PROFIusb. Used with the free STEP7 driver, the device can also provide a PG/PC adapter for programming Siemens controllers.

Step5 displays “Error 0334” when I want to establish a connection via the S5-PCLink

Please download and install the software patch s5vir122.exe from our download area.

I cannot change any settings in the S5-PCLink (e.g. IP address, name, etc….) with the S5-LanManager

Firmware version 1.03 or newer is installed in the S5-PCLink (check S5-LanManager).

Please download an update of the S5-LanManager from our web site. Replace the installed files (C:\Program Files\Softing\S5-PCLink\… ) with those from the S5LanManager_update.zip file.

Communication with the PLC is sporadically broken or cannot be established at all

On S5 PLCs of type S5U115-944 and -928B, the power sources needed by our S5-PCLink are often defective. This is indicated by a failure to connect to the PLC (green LED on S5-PCLink flashes once approx. every 4 seconds) or a broken connection at irregular intervals.

Pinging the S5-PCLink works.

You will need a power source adapter that can be added between the PLC and the S5-PCLink, and provides the power sources.
Please contact our sales department if you need this adapter.

What is the default IP address of the S5-PCLinks (factory setting)

There is no default IP address setting. The IP address is automatically assigned by the DHCP server per default.

If there is no DHCP server available, then the module will use a random address from the IP address space 169 – … (after about 1 minute).

In case the device will not be shown in the S5-LAN-Manager then connect it directly with a crossover network cable and your PC. Please disable the Firewall. You can then configure the device in the S5-LAN-Manager. (For the operation mode this function is not necessary).

S5-PCLink is not found in the S5-LAN-Manager

Possible causes:

  • IP address / port is blocked by the firewall . Please disable the firewall and then search again in the S5-LAN-Manager. Ports see below.
  • A virus scanner could also block the communication, so please turn off the virus scanner.
  • There is a router between the PC and the module (especially NAT router), which does not forwards the search to the broadcasts.
  • If a VPN connection is used then the required ports must be free.
