Addresses Tab - Unspecified UDP Connection
An unspecified UDP connection can be used in two ways:
Free UDP Connection
To configure a free UDP connection, select the “Address assignment in block”
check box. The input boxes for the remote IP address and the remote port are
then deactivated since the destination addresses are now specified by the user
program.
Connection to a remote station in a different project
You can specify the remote IP address and the port for any destination station.
The destination station can be in the current STEP 7 project or in another
project.
Please note:
Since no connection is actually established with UDP (datagram service),
communication on the configured UDP connection is only possible when the
partner addresses (IP address and port ) are specified.
