In OptoScript block, text may be deleted and may cause compiler errors
- PAC Control Professional
- PAC Control Basic
On rare occasions, compiling a PAC Control strategy may show unexpected compile errors in OptoScript blocks. When you investigate the OptoScript block, you may find that content appears to be missing and the OptoScript block may be truncated.
This issue is very rare and the cause is still under investigation. In PAC Control R10.5a, diagnostic code was added to flag the issue.
The diagnostic code is executed in the following situations:
- When entering an OptoScript block.
- When compiling an open chart.
- When compiling the strategy, it will check any chart that is open.
If PAC Control finds the issue when entering an OptoScript block, it displays a pop-up message. In addition, it logs the message(s) to a file named
DiagFourNulls - <strategyname>.txt
, which it saves in this folder:
c:\ProgramData\Opto22\PAC Project\PAC Control\
If the issue occurs, contact Opto 22 Product Support at email@example.com and send the following:
- The log file
- A description of what led up to the issue
- An archive of the strategy in the current state
- The previous archive
Opto 22 is investigating this issue.
