GRV-R7-I1VAPM-3: energy accumulation channels report 3x the expected value


Applies To:

Firmware for GRV-R7-I1VAPM-3

Versions Affected:

All versions prior to 3.4.0

Resolved In Version:

3.4.0


Symptoms:

On a GRV-R7-I1VAPM-3 module, channels 57, 58, 59, 60, 61, and 62 report an accumulation of values. With this issue, these channels report approximately three times the expected value.

Workaround:

Do one of the following:

  • Workaround 1: Divide the affected channel's value by three to approximate its expected value. For example, divide the value of channel 57 by 3.
  • Workaround 2: Sum the values of the three channels that contribute to the affected channel's value to determine the accumulation value. For example, sum the values of channels 13, 31, and 49 to determine the total net energy, which is provided by channel 57. Note: For channel 58, the sum is the absolute value of channels 13, 31, and 49; channel 58 = abs(channel 13) + abs(channel 31) + abs(channel 49). For details about channels, see the groov RIO Energy Monitoring Unit Data Sheet (form 2352).

Resolution:

Opto 22 has resolved this issue.
