Applies To:

Firmware for the following modules:

  • GRV-IAC-24

  • GRV-IACIHV-12

  • GRV-IDCIFQ-12

Versions Affected:

R1.3a

Resolved In Version:

R1.3b


Symptoms:

While using a digital input configured for period measurement (for example, Period (One-Time) in groov Manage or Period in PAC Control), the period measurement value may be inaccurate and is low by 37.5%.

Workaround:

Since the value is always reported low, multiply the period measurement by 1.6 to correct the value.

Resolution:
