Operation Command

The following three types of operation commands are available.

Operation Command

Automatic Measurement Start Command Functions as the trigger signal to start automatic measurement.
Software Reset Command
Parameter Initialization Command
Operation commands are specified by a command code in the command frame.
6-8 CompoWay/F Communications Format on page 6-14 and 6-9 Modbus RTU Communications
Format on page 6-22 describe the command frame/response frame configuration.
Automatic Measurement Start Command
Automatic measurement starts regardless of whether the external contacts connected to the trigger
input terminals are ON or OFF.
The Automatic Measurement Start Command operation is
slightly different from operation due to a trigger signal from
external contacts. To keep the trigger signal ON, the
external contacts must be kept OFF*. However, with the
Automatic Measurement Start Command, the trigger
signal is kept ON with a one-shot command.
* When the setting value of the Trigger Signal Reverse setting parameter
is OFF
To stop a measurement started by the Automatic Measurement
Start Command, execute a Software Reset Command from the
communications commands.
Overlapping between the timing of the trigger by an external contact and the Automatic Measurement
Start Command from the communications commands is a post-win. For example, if the measurement
operation starts by an external contact and the Automatic Measurement Start Command is input before
the measurement operation completes, the measurement started by the external contact is reset, and a
new measurement operation by the measurement start command starts.
While it is possible to use the external contact and communications command together, it becomes difficult to
understand the operation when seen from the outside, and therefore, it is recommended to use either of the two.
 Timing to Execute the Automatic Measurement Start Command
Execute the Automatic Measurement Start Command when all the following conditions are met.
(1) The load contactor is OFF (turned OFF from power line).
(2) The K7GE-MG is in the Operation Level.
(3) The K7GE-MG is not performing manual measurement.
(4) The K7GE-MG is not performing automatic measurement.
