Debugging Communication Between SuiteLink
and an I/O Server
If you have successfully applied the debug techniques listed in the previous section and
are still experiencing communication problems to a server that is attempting to
communicate using the SuiteLink protocol, perform the following steps as listed below:
Verify the I/O Server supports the Wonderware SuiteLink protocol, that is, the
I/O Server is version 7.0 or above.
Try communicating to the I/O Server using the DDE protocol. If this is not
possible, then proceed to the next troubleshooting section otherwise continue with
the following steps:
1. Verify Microsoft's TCP/IP stack is installed and configured properly.
2. If you do not have an Ethernet card to bind to the TCP/IP stack, install the
3. Install the Microsoft TCP/IP stack.
WindowMaker and correct it in the Access Name definition.
server program. Data should now appear in the server's program window to
indicate that WindowViewer and the server are communicating.
The data in the server's program window indicates the read and write
messages that the server is sending to and receiving from the PLC. (These are
not error messages, only status messages are written to the server's program
window.)
Logger to check for error messages. For example, a common error message is:
"Error for DDE: OMRONFO|HLPLC!<null>("item") Advise failed"
This message appears when the item defined in one or more tagnames is invalid for
the server.
InTouch tagnames use specific naming conventions when accessing data from
a server. The valid item names for all Wonderware servers are documented in
their respective User's Guides. Typically, the item naming conventions used
by each server are consistent with the names used by the equipment
manufacturer.
For more information on the Wonderware Logger, see your online
"FactorySuite System Administrator's Guide."
SuiteLink uses the Microsoft TCP/IP stack for its communications even if the
client application and the server reside on the same node.
