Applies To:

GROOV-AR1
GROOV-AR1-BASE
GROOV-AR1-SNAP
GROOV-AT1
GROOV-AT1-SNAP
GROOV-SVR-WIN
GROOV-SVR-WIN-BASE

Versions Affected:

groov View R3.5a through R4.0d for all scanning
GRV-EPIC-PR1 firmware 1.0.0 through 1.1.0 for all scanning

Resolved In Version:

groov View R4.1a
GRV-EPIC-PR1 firmware 1.3.0


Symptoms:

groov View ignores user choices for three options on the Modbus device configuration panel:

  • Use function code 06 when writing a single register (default is off)
  • Use function code 05 when writing a single coil (default is off)
  • Do not use function code 22 when writing a single register bit (default is on)


Note: Prior to groov View R3.5a, those options were reflected in gadget display values only, but were not used in Event or Trend scans. You could see errors or invalid values in Events or Trends, while gadgets appeared to work.

Resolution:

Opto 22 has resolved this issue.
