The following table describes the various settings in the dialog box.
Setting
Connection Assigns a name to each connection.
Name
Connection I/O Select one of the following connection I/O types according to the target connection.

50 ms (data refreshed once every 50 ms).
Timeout Value Sets the time until a connection timeout is detected. The time out value is set as a multiple of the
packet interval (RPI) and can be set to a 4, 8, 16, 32, 64, 128, 256, or 512 multiple. The default set-
