Driver dialog SAIA connections

Define a connection for every PLC and set the maximum read block size under "Register max. block size". The S-Bus address is the staton number of the PLC in the SAIA net and matches the Net address (Net address in zenon V6) in the variable definition.

There are three types of connection:

serial connection (PGU, S-BUS)
Ethernet connection (S-BUS TCP/IP)
Gateway connection (data exchange via another physical connection)

Every connection type is marked with a different symbol in the list. Additionally, the connection is displayed for every entry.

Click the button "Add..." to open the configuration dialog for creating a new connection

Click the button "Edit..." to open the configuration dialog for changing an existing connection

Click the button "Delete" to remove an existing connection

Click the button "Test" to check an existing connection.
