Configuring a System with several Data Managers


Several Data Managers can be integrated into one system. There are three options for using the Data Manager:

  • Stand-alone master

  • Superordinate master

  • Slave

In systems with master and slaves, all slaves must first be commissioned to add them when the master is commissioned. To subsequently use a stand-alone master or a superordinate master as a slave, the product must be reset to the default settings.

Stand-alone master

Select the option Stand-alone master (recommended) 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 master

Select the option Superordinate master 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.

Slave

Select the option Slave 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 as master, all slaves must first be commissioned to be able to integrate them into the system of the superordinate Data Manager. To do this, select the operating mode Control and the signal source Modbus for the subordinate Data Manager.
