Get Analog Totalizer Value Returns -1.#QNAN in PAC Control


Applies To:

Firmware for GRV-EPIC-PR1

Versions Affected:

1.0.0 through 1.3.0

Resolved In Version:

1.3.1


Symptoms:

In a PAC Control strategy, you must first use the Set Analog Totalizer Rate command before using the Get Analog Totalizer Value command. If the analog point is on a GRV-EPIC-PR1 I/O Unit, the Get Analog Totalizer Value command returns -1.#QNAN instead of the totalized value.

Workaround:

After using the Set Analog Totalizer Rate command, immediately use the Get & Clear Analog Totalizer Value command once. The Get Analog Totalizer Value command will work correctly after that.

Resolution:

Opto 22 has resolved this issue.
