Note: Beta feature
Telecontrol is currently available as a beta feature
You can configure an IEC server in two ways:
-
Option 1: Manually configure a server: If no grid operator template is available or when you need complete control over the server and data point configuration.
-
Option 2: Import a pre-filled grid operator template: When a predefined template is available. Templates include pre-filled IEC data point definitions and can significantly reduce setup effort.
Regardless of the method you choose, you must review the configuration and complete any project-specific settings before using the server.
Prerequisites
-
IEC clock synchronization is configured under Settings > Date/Time > Time synchronization > select IEC - Clock synchronization.
-
The required communication interface is configured (RS-485 for 101, Ethernet for 104).
-
Network and (optional) firewall settings allow communication with the grid operator.
Caution
The server is active by default. If you do not want to exchange data with the grid operator during setup, deactivate the 
Warning
To prevent data loss, export the configuration as a backup after completing the server and data point configuration.
Option 1: Manually configure an IEC server
Steps
-
Go to Telecontrol > Configuration > Add new IEC server configuration.
-
A new IEC server configuration is created.
-
On the Interface tab, choose protocol 101 or 104 from the dropdown.
-
Different fields will appear depending on the selected protocol.
-
Configure the fields in the Interface, Protocol, and General configuration tabs. Find descriptions of the fields in the tables below.
-
Select Save.
You can now configure data points on the server.
Protocol 101 (RS-485)

Interface |
Select which RS-485 interface is used on the bluelog:
|
|
Baud rate |
Select the server’s baud rate. |
|
|
Frame settings |
Define the serial communication format. |
|
|
Protocol |
Link address |
Define the address (integer) of the remote IEC station receiving the communication. The link address must match the address configured on the connected device. Device ID / RTU Address. |
|
Link address length |
Number of bytes used to encode the link address. Must match the configuration of the remote station. |
|
|
Cause of transmission length (COT) |
Number of bytes used for the COT. |
|
|
Common address length (COA) |
Number of bytes used for the COA. |
|
|
Information object address length (IOA) |
Number of bytes used for information object addresses (data points). |
|
|
Balanced mode |
By default, the master/primary server initiates communication. Activate the toggle |
|
|
Poll rate |
How frequently the master asks for new data. |
|
|
Acknowledgement timeout (ms) |
Maximum time to wait for a response or acknowledgement. A communication error is detected when the remote station does not answer in time. |
|
|
General configuration |
Counter Reporting Mode |
Define how values are accumulated and sent: when requested, periodically, in real time, or with reset after reading. |
|
Counter snapshot interval |
Duration during which surveillance stops (Counter Reporting modes A & B only) |
|
|
Report initialization mode |
Decide whether to send all values at bluelog startup |
|
|
Modbus sending interval |
How often a telegram is sent to devices using output value points pointing to devices via Modbus. |
|
|
Ageing interval |
Period after which signals are ignored and the bluelog marks an IEC command with a timestamp as invalid. |
Protocol 104 (Ethernet)
Note
The maximum telegram length is fixed to 255 bytes.
Option 2: Import a pre-filled grid operator template
The bluelog provides a selection of grid operator templates that contain pre-filled IEC data point configurations, such as addressing, transmission modes, and mapping definitions. The pre-filled data point definitions apply to the standard data points listed for the specific grid operator.
Templates do not define actual values for device data points (inverters, etc.) or default values for data points. You must define these after loading the template.
Import a template
Steps
-
Go to Telecontrol > Configuration.
-
Select Load configuration.
-
Select Import from template.
-
Select the relevant template from the dropdown.
-
Select Apply.
-
The configuration loads.
-
Remove any data points that are not defined in the data point list of your specific project (see examples below) and adapt configurations as necessary.
You can now define default values for data points.
Example: Remove unnecessary data points
Templates may contain data points that are not relevant for your system. For example, you should remove data points that:
-
Belong to energy sources that are not installed, such as PV, BESS, or wind.
-
Refer to grid connection points that do not exist in your project.
Export and reuse configurations
Once you have configured the Telecontrol setup, you can export it locally. You can use this as a backup, and you can reuse it as a template on other bluelogs.
Export an IEC server configuration
Prerequisites
-
You have completed the Telecontrol configuration on a bluelog Neo.
Steps
-
On the bluelog, go to Telecontrol > Configuration.
-
Select Export configuration.
-
A JSON file is downloaded.
-
Save the file locally for reuse.
You can now reuse the server configuration.
Import a saved IEC configuration
Prerequisites
-
You have exported a Telecontrol configuration.
Steps
-
Go to Telecontrol > Configuration.
-
Select Load configuration.
-
A window appears. Select Import from file > Select file.
-
Select Save and activate.
-
Select Apply.
The configuration loads. You can now adapt the configuration as required.
