Pat, We have seen problems with FoxAPI v.4.3.3 and OSI PI where the FXBAIS interface would not start at all. We had to back down to v.4.3.2 to get FXBAIS to start. There may be related problems with the Matrikon OPC application. I know that Matrikon tends to be a bit behind the curve when others upgrade their software, such as when Java does upgrades and it breaks the Matrikon Alarm Manager web interface.

Both processes (FoxAPI and Matrikon) show as running in task manager but the OPC server returns an error stating that the station does not have FoxAPI...after it retrieves version information for it. 70 series AW with FoxAPI 4.3.3 Any thoughts or help are appreciated.
