Using a pointer table in a PAC Control subroutine may result in unexpected behavior


Applies To:

Firmware for:

  • SNAP-PAC-S1, SNAP-PAC-S1-FM, SNAP-PAC-S1-W
  • SNAP-PAC-S2, SNAP-PAC-S2-W
  • SNAP-PAC-R1, SNAP-PAC-R1-FM, SNAP-PAC-R1-W, SNAP-PAC-R1-B
  • SNAP-PAC-R2, SNAP-PAC-R2-FM, SNAP-PAC-R2-W
  • SoftPAC

Versions Affected:

R10.0a through current


Symptoms:

You may observe erratic behavior (like those listed below) if your PAC Control strategy contains logic that passes a pointer table as a parameter to a subroutine:

  • Strategy logic does not perform correctly
  • Controller resets

Workaround:

Modify the logic in your PAC Control strategy to pass a pointer instead of a pointer table to a subroutine.

Resolution:

Opto 22 has resolved this issue and will include the fix in an upcoming release.
