5.5.3 Checking ISO-on-TCP Connection Properties
Overview Tab
The overview shows all the configured ISO-on-TCP connections and their
parameters (cannot be modified here).
You can adjust the width of the columns in the table.
For an example of this display, refer to Section 5.3.4 (the ISO transport
connection).
Parameter
Description
Local ID This is the connection ID of the ISO-on-TCP connection (STEP 7 connection
configuration; DWORD)
Name (loc.
endpoint)
Entered connection name. This identifies the ISO-on-TCP connection.
CPU /
Applications
If you display all the ISO transport connections being operated in this station in the
multiprocessor mode (with PC stations: multiple applications), the CPU/application that
is the endpoint of the particular connection is specified here.
R/S or via CP With S7-CPs: Rack/slot of the local CP via which the connection is established.
With PC stations: Display of the CP over which the connection is maintained.
Partner
address
Specifies the remote IP address of the connection.
Local TSAP Local Transport Service Access Point (8 characters default)
Remote TSAP Remote transport service access point (8 characters default).
Mode Displays the mode configured in the ”Options” tab.
Status Indicates the current configuration of the connection.
“Connections without assignment” are indicated by “No local CP/No remote CP” in the
status column and a “!” character at the end of the“Local ID” (for example: 0002 A000!).
Connections you are currently editing are also indicated by “!” at the end of the local ID.
Connection Overview with Multiple CPUs in an S7 Station
If you operate more than one CPU in your S7 station, you can click the button to
extend the overview to the connections on all CPUs.
