A gateway enables communication between networks that are based on different protocols. By using gateways, completely different (heterogeneous) networks can be connected with one another.

The gateway supplied as standard with the versiondog system allows you to connect TCP/IP networks with H1, MPI or PROFIBUS networks. This allows the server to communicate with the following devices that are not accessible via the TCP/IP network:

The CSC Gateway add-on additionally enables network participants to communicate across the boundaries of two TCP/IP networks. Various scenarios can be implemented via the CSC gateway, e.g. client-server communication (e.g. Check-In or Check-Out), server-agent communication or the synchronization of two servers.

The CSC Gateway is an add-on and must be licensed separately.

System requirements

No special hardware or software is required for using the gateway. The standard hardware and software requirements apply. The latest hardware and software requirements can be found in the tutorial Installation requirements.

In addition to the operating systems listed under Installation Requirements, Microsoft Windows NT 4.0 with SP6 and Microsoft Windows 2000 Professional are also supported.

FAQ:: Why does the connection to devices that are accessed via the H1 protocol fail, even though the INAT H1 driver is installed?

Possible scenarios

  1. Upload jobs with the H1 protocol selected as the access path do not work at all A. Upload jobs with the H1 protocol selected as the access path suddenly stop working after further editors are installed (e.g. TIA Portal or SIMATIC NET)

  2. Upload jobs with the H1 protocol selected as the access path do not work at all These generally do not function.


If you are using the H1 protocol for a device upload job, all H1 protocols apart from the INAT H1 protocol must be deactivated.

Proceed as follows

  1. Go to properties of the LAN connection.

  2. Check to see whether in addition to the INAT H1 there are any other H1 protocols still activated (e.g. SIMATIC Industrial Ethernet (ISO)). If so, deactivate them.
