Importing chart may cause PAC Control to crash


Applies To:

  • PAC Control Professional
  • PAC Control Basic

Versions Affected:

All versions prior to R10.5a

Resolved In Version:

R10.5a


Symptoms:

On rare occasions, when you import a chart into a PAC Control strategy, if the I/O of the chart being imported does not match the I/O of the strategy, PAC Control may crash. If the chart imports successfully, the strategy may not compile or it may crash when you select Tools > Regenerate Reference Counts.

Conditions for the issue to occur:

  • I/O points are SNAP or groov (G4 is not affected).
  • The I/O point being imported is on an I/O unit with the same name as an I/O unit in the target strategy.
  • There is already an I/O point configured in the same point location in the target strategy, but the point name is different.

Workaround:

Follow these steps to work around the issue:

  1. Create a new strategy.
  2. Import the chart into the new strategy. This helps you see the I/O units and channels that are referenced in the chart being imported.
  3. Compare the I/O modules and channels of the new strategy with the target strategy (the strategy you want to import the chart into).
  4. Modify the target strategy to eliminate the conditions mentioned above and then save the target strategy.
  5. Export the chart from the new strategy.
  6. Import the chart into the target strategy.
  7. Save the target strategy.
  8. Select Tools > Regenerate Regenerate Reference counts.
  9. Select Compile > Compile All.
