Gateways

This topic describes what gateways are used for and which gateway scenarios are supported.

A gateway allows networks based on different protocols to communicate with each other.

The gateway supplied with the setup connects the server's TCP/IP network to H1, MPI, or PROFIBUS networks. This allows the server to communicate with devices that it cannot reach directly through its TCP/IP network:

  • An automation device in the other network
  • An automation device that can only be reached indirectly through a head controller
  • An SSH server
  • Agents

The CSC Gateway also enables network participants to communicate across the boundaries of two TCP/IP networks. Various scenarios can be implemented using the CSC Gateway, for example, client-server communication, such as Check-In or Check-Out, server-agent communication, or synchronization of two servers.

System requirements for gateways

No special hardware or software is required to use the gateway. The general hardware and software requirements apply.

Info

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

FAQ

Connection to devices using the H1 protocol fails

Possible scenarios

  1. I have set up uploads and selected the H1 protocol as the access path. After installing other editors, for example, TIA Portal or SIMATIC NET, these suddenly no longer work.

  2. I have set up uploads and selected the H1 protocol as the access path. These generally do not work.

Explanation

If you use the H1 protocol to upload a device, all H1 protocols except the INAT H1 protocol must be deactivated.

Procedure

  1. Go to Properties of LAN connection.
  2. Check whether other H1 protocols are activated in addition to the INAT H1 protocol, for example SIMATIC Industrial Ethernet -ISO, and deactivate them.
