Advanced Modbus configuration

Here, further settings can be selected for the Modbus master functionality. These settings apply to all configured Modbus masters.

Transmit interval

Here, you can set an interval, at which the measurement data is to be transmitted from the KOSTAL Smart Energy Meter. The Energy Manager usually transmits its measurement data via the Modbus master as soon as it is available. If the interval is activated, the data is transmitted at a regular interval instead, regardless of when it is available. Only the current measuring values at the transmit time are ever communicated. Mean values are not produced for the interval.

Parameter	Explanation
Enable fixed transmit interval!	Activated KOSTAL Smart Energy Meter data is transmitted at a fixed transmit interval. Selection of interval from drop-down menu. Deactivated KOSTAL Smart Energy Meter data is transmitted after each measurement cycle (200ms or 500ms).
Set transmit interval	Select a transmit interval using the drop-down menu or enter a user-defined transmit interval in seconds at which you want the KOSTAL Smart Energy Meter to send its data.
Averaging over transmit interval	Averaging over transmit interval switches on averaging calculations for the transmit interval. Activated Calculates and transmits a mean value for all measurement cycles within the set transmit interval. Deactivated Transfer current measuring values at the end of the transmit interval.

Parameter

Explanation

Enable fixed transmit interval!

Activated
KOSTAL Smart Energy Meter data is transmitted at a fixed transmit interval. Selection of interval from drop-down menu.

Deactivated
KOSTAL Smart Energy Meter data is transmitted after each measurement cycle (200ms or 500ms).

Set transmit interval

Select a transmit interval using the drop-down menu or enter a user-defined transmit interval in seconds at which you want the KOSTAL Smart Energy Meter to send its data.

Averaging over transmit interval

Averaging over transmit interval switches on averaging calculations for the transmit interval.

Activated
Calculates and transmits a mean value for all measurement cycles within the set transmit interval.

Deactivated
Transfer current measuring values at the end of the transmit interval.

Register configuration

Groups of registers can be selected here, which are to be written in master mode. The system load of the KOSTAL Smart Energy Meter can therefore be reduced if all of the registers are not required. This may be necessary if lots of devices are connected to the KOSTAL Smart Energy Meter.

The arrow on the right can be used to drop down a detailed list of registers, which are contained in the respective groups.

The following registers can be activated or deactivated:

INFO

You will find information about the respective registers in the KOSTAL Smart Energy Meter- Interface Description Modbus documentation in the download area for the KOSTAL Smart Energy Meter.
