Modbus configurator
Last modified:
To connect devices to the blue'Log that are not covered by the all-in-one driver, you can use the Modbus configurator (license required). The Modbus profiles created are specific to the blue’Log where the license is applied. Supported device categories for the Modbus configurator include inverter, meter, sensor, battery, tracker, string monitoring, status DI external, and genset. Meters can be used for power control if a Modbus profile is set up. However, inverters can not manage power control.
You can view the imported profiles on your blue’Log under Configured Modbus profiles and have the option to download, edit, or delete them from there.
Note
The Modbus configurator cannot be used to:
Scan two logical devices (Modbus profiles) that share the same Modbus address (IP or bus address), even if they originate from a single physical device
Scan virtual devices, such as virtual meters
Supported device categories
Inverter
Meter
Sensor
Battery
Tracker
String monitoring
Status DI external
Genset
Power plant controller
Supported data points
It is not possible to import values that return an error message. All supported data points can be viewed in the import specification.
Import a Modbus profile
You may want to re-use an existing Modbus profile, for example, if a driver is not available or cannot be generated by meteocontrol. This is particularly useful when applying the same profile to multiple blue'Logs.
Prerequisites
blue'Log XC with firmware ≥ 17.0.11
To use this function, you need a license: see License and Modbus configurator data sheet.
Advanced knowledge in using Modbus communication protocol
Modbus interface description from the manufacturer of the device you want to configure
Steps
If you have an existing Modbus profile, for example from another blue'Log, select Import Modbus profile and upload the file (.JSON).
The profile is imported.
Under Basic settings, you can edit the Driver name.
Under Measured values, you can edit the settings of the measured values by selecting the Pen icon.
Optional: Under Device information, you can enter the serial number, model, and firmware.
Add a new Modbus profile
Prerequisites
blue'Log XC with firmware ≥ 17.0.11
To use this function, you need a license: see License.
Advanced knowledge in using Modbus communication protocol
Modbus interface description from the manufacturer of the device you want to configure
Steps
To create a Modbus profile for a new device, select New Modbus profile.
Select Configuration help in the Create/edit new Modbus profile area for detailed help.
Under the Basic settings tab, you must enter at least the Driver name and Device category.
Under the Measured values tab, select the Plus icon to add the values that should be read from the device. This information can be found in the Modbus interface description from the manufacturer of the device you want to configure.
Optional: Under the Device information tab, you can enter the serial number, model, and firmware.
Create or edit a Modbus profile
Example: Modbus profile
The following example shows a meter that measures active power and active energy in a power control scenario.
Step 1: Basic settings |
|---|
 New Modbus profile: basic settings |
Step 2: Measured values |
Measured values: active energy and active power. Factor: 1000 to show kWh.  New Modbus profile: measured values |
Step 3: Device information (optional) |
The device information allows you to use the Modbus definition of the device to identify it. When you have successfully scanned for your Modbus device under Meters, it will then appear under Installed devices. If you wish to use the data in further tools (VCOM or SCADA), this will help you to identify the configured device.  New Modbus profile: device information (optional) |
Read multiple digital input signals contained in one register
It is possible to use the same register to address multiple digital input signals in a byte using the data type bits. This is useful for example if you have many digital signals using a Status DI external device, you can simplify how they are read.
For this, navigate to Modbus configurator > Create/edit new Modbus profile > Measured values > Offset column. See the Configuration help for additional assistance.
