iFIX Driver not reading ALL tags in a SLC5/05

I have a bazaar situation where an iFIX V4.5 existing installation is now not reasding all the IO in a serially attached SLC 5/05??

If you look in the PLC database, the values are there and changing but the iFIX app which WAS running fine for months is now only showing some of the analog values and some of the digital values.

Reboot of both the PLC and PC fixed nothing!

Any ideas - this is on a booster station and is the only link to the PLC.

Look at the driver.
Has anything happened to the PC in the last little while?
What driver are you using?
It might be worthwhile to reinstall the driver.

Take a look at the iFix Mission Control. It should give you diagnostics for the I/O driver that should help isolate the cause of your issue.

Make sure your I/O driver is running and that the data blocks in question are enabled in the driver.


Are any I/O points working?

PC'c running fine.
We're using the RSLinx driver.
Reinstall sounds like a good bet.

Thanks

Make sure someone hasn't changed it from SLC to PLC-5, I did that once and got similar results.
