Device function
Several Data Managers can be integrated into one system. It is possible to choose between the following device functions:
System Manager
Superordinate System Manager
Subordinate System Manager
In systems with a superordinate and subordinate System Managers, all subordinate System Managers must first be commissioned to be able to integrate them into the system of the superordinate System Manager. To subsequently use a System Manager or a superordinate System Manager as a subordinate System Manager, the product must be reset to the default settings.
System Manager
Select the option System Manager in the installation assistant if you use the Data Manager as a stand-alone device without other subordinate Data Managers for open-loop or closed-loop control of your system.
Superordinate System Manager
Select the option Superordinate system manager in the installation assistant if you use the Data Manager as a superordinate device with other subordinate Data Managers for open-loop or closed-loop control of your system. With this option, the superordinate Data Manager forwards the open-loop or closed-loop control commands to the subordinate Data Manager via Modbus. For this, subordinate Data Managers must be integrated as Modbus devices into the system of the superordinate Data Manager. Meters at the grid-connection point must be connected to the superordinate Data Manager.
Subordinate System Manager
Select the option Subordinate system manager in the installation assistant if you want to use the Data Manager as subordinate device. With this option, the subordinate Data Manager receives the open-loop and closed-loop control commands of a superordinate device. These commands are forwarded as open-loop control commands to the connected devices. In systems with a superordinate Data Manager, all subordinate System Managers must first be commissioned to be able to integrate them into the system of the superordinate Data Manager. In systems with inverters, all inverters must first be commissioned in order to accurately display the system power. The operating mode Control and the signal source Modbus must be selected for the subordinate Data Manager. The option Optimized closed-loop control/open-loop control must be disabled. The Modbus server must be activated in the subordinate Data Manager. Under the Direct seller settings, the Source for external setpoint must be activated and Modbus must be selected.
