Verify the PLC is properly configured and the cable is good by using the
programming software for the PLC.
When testing, run the programming software and communicate with the server at the
same time.
The ability to perform this test depends upon the type of PLC that you are using.
Reinstall the I/O Server and verify that you are using the latest version.
We continually improve our servers and using the latest version will guarantee the best
results.
New versions of the Wonderware I/O Servers are released regularly on the
Knowledge Base CD and they are also available to Comprehensive Support
customers on the Wonderware Bulletin Board System (714-727-0726) or from the
Wonderware WEB site at: http://wondertech.wonderware.com.
Move the I/O Server’s configuration file to another location on the computer’s
hard drive. This will clear all configuration for the I/O Server, then reconfigure
the I/O Server.
Wonderware server configuration files are typically named exactly the same as the
server’s executable name but with the .CFG extension, e.g.,
OMRONFO.CFG.
Refer to the Configuration File section of the server user’s guide for the exact name
of the configuration file.
If possible, reinstall the Windows operating system.
Some of the files that are installed on your computer or the NT registry may have been
corrupted or accidentally modified.
If these troubleshooting suggestions do not solve your problem, there may be a
problem with your computer. There are many subtle differences between the
various computer hardware brands. Try using a computer that is a different
brand and select one that meets the following criteria:
11. A different PC manufacturer. If this is not possible, try a different PC model from
the same manufacturer.
12. The computer does not use an OEM (Original Equipment Manufacturer) version of
Microsoft Windows. When you start up Windows, only the Microsoft Windows
logo should display, not a logo from a hardware manufacturer. We highly
recommend you use only a Microsoft Windows product. Contact your vendor to
determine if installing an off-the-shelf copy of Microsoft Windows will cause any
problems.
If you feel you have tested all possible situations that may be causing your failed
I/O communications, contact your local Wonderware distributor for technical
support.
