Network topology

The TwinCAT Database Server can be carried out in the network in several ways. The network topology mostly will be controlled by the database type, the local terms, and the area of application.

In the following figure you can see several network topologies where the TwinCAT Database Server can be applied.

Important!

For a smooth remote access of the TwinCAT Database Servers to a database some things must be regarded at the database side:

• Is the remote access allowed in general?
• Note the quorum of the concurrent opened connections. (If the TwinCAT Database Server needs to open several connections)
• Has the user who wants to register enough rights
• Is the Firewall of the Remote Systems configurated?

For furthermore details how to configure your database server you can find in the corresponding documentation of the database.
