Basically what happened is that Citect
only supports Trend tag names of 16 characters but the customer had
wanted longer trend tag names so they manually went in and
increased the field width size for the trend.dbf file in 5.01. It
has always been our policy to advise customers that while they may
do this there is no guarantee that there will not be problems in
future versions should they upgrade. This is what has happened
here. Citect 5.31 does not like it when you have trend tag names
greater than 31 characters and this is what is causing the startup
error. You can still save your current trend data by doing the
following:
- Rename the trend name to be less than 32 characters in length
and also turn on extended forms and in the 'File Name' field put
the long file name (ie.[Data]:EPS_PlantWater_DischargePressure) .
The 'File Name' field will accept this fine but the trend name will
not.
