Meteocontrol

The Teleport can connect to blue’Log XC datalogger with firmware ≥ 10.0.8 using Modbus TCP over ethernet. The logger comes with a number of available licences. In order to provide remote active power control to assets connected to the datalogger, the Power Control Modbus license is required. You can order the license directly from Meteocontrol.

Connecting a meter to the blue’Log

When connecting a meter to the blue’Log datalogger for use as a reference measurement in local power limitation, ensure that the current direction aligns with that of the solar assets (IEC 61850-7-520 Producer Reference Frame or generator sign convention). If the current direction is incorrect, the Teleport may be unable to control the curtailment setpoint of the datalogger and the connected assets.

Modbus TCP over ethernet

1. Connect the blue’Log with an Ethernet cable.
   With a router:
   1. Connect an Ethernet cable between the router and the blue’Log, as well as between the router and the ETH1 port of the Teleport. Please navigate to our appendix for more instructions on how to integrate with a router.
   Without a router:
   1. Connect an Ethernet cable between the Teleport and the blue’Log.
   2. Press the OK button on the blue’Log and input your user ID to log in via the display. The default user IDs are 0010 for full access, and 0001 for restricted access.
   3. Navigate to the Main menu, Telecommunication and Network menu using the directional pad and buttons.
   4. Disable DHCP and set the network parameter to static.
   5. Configure the following settings, with values as described in Static IPs for a direct asset connection.
      • IP address
      • Subnet mask
      • Gateway
2. Navigate to the web interface of the blue’Log.
3. Activate the Modbus power control license, following the License activation steps if it is not yet activated.
4. Navigate to the POWER CONTROL and Operating data menu and configure the following properties under the Plant data section.
   • Agreed connected active power P_AV: the nominal active power in kW.
5. Navigate to the POWER CONTROL and Active power menu.
6. Click the active button of the Active power control at the top of the page to enable control and configure the following properties.
   • Operation mode: OPEN LOOP
   • Setpoint command method: Variable fixed value Pvar Modbus
7. For optional fallback configuration in the Fail-safe operation section, configure the following properties.
   • Behaviour in event of error: Default setpoint
   • Waiting time: 60 s
   • Fallback value: enter the desired fallback percentage.
8. Press the Save button at the bottom of the screen.

License activation

These steps explain how to activate the license on the blue’Log. The Modbus power control license needs to be activated before the Teleport can be used to communicate with the blue’Log.

1. Go to the SYSTEM and Licence menu.
2. In the License upload section, click on Select file and upload the license via the Upload license button.
3. A green check mark in the table of Installed licenses should appear next to Power Control and Modbus Power Control, indicating a successful license activation.
