3.4 Checking the WinCC channel diagnostics
Procedure
1. Start the "Channel Diagnosis" WinCC channel diagnostics on the activated OS server
with the Start menu command "SIMATIC > WinCC > Tools > Channel Diagnosis".
Operation of the Start menu via the OS must not be blocked for this procedure to work.
2. The application window for "Channel Diagnosis" opens.
The left section of the "Channels/Connections" tab shows the status information for all
installed channels and their connections.
3. Check the icons next to the "SIMATIC S7 Protocol Suite" channel name and the
connection.
The status of the channel or the connection is correct when a green check mark is
displayed in front of the respective entry. The meaning of the icons are available in the
table "Overview of status displays."
4. If there is no green check mark in front of the name of the channel and connection, select
the connection in the left window. Check the entries of the counters "First Error Code"
and "Last Error Code" in the right window. The entries provide information about errors
detected.
The shortcut menu of the value display provides you with direct help.
5. On the "Configuration" tab, select the status and error displays that you want to output to
the log file. To do this, select the "SIMATIC S7 Protocol Suite" channel and configure the
error displays.
You can find a description of this under the topic "How to configure the trace function of a
channel" in the WinCC online help.
