A simulated counter on a groov EPIC I/O unit or groov RIO provides erratic results


Applies To:

  • SoftPAC
  • Firmware for the following:
    • GRV-EPIC-PR1
    • GRV-EPIC-PR2

Versions Affected:

SoftPAC: R10.0 to current
groov EPICs: All versions prior to 3.5.0

Resolved In Version:

groov EPICs: 3.5.0


Symptoms:

If a PAC Control strategy includes a groov RIO or groov I/O unit that is either not physically available to the system or is currently configured in the strategy with communication to the I/O unit disabled (normally for testing), the counter provides erratic results. For an I/O unit with communication disabled in the strategy, you can simulate a counter by using the PAC Control IvalSetCounter() command to set the counter value and the GetCounter() command to read it.

Resolution:

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