Configuring Modbus Interfaces

  • With Sunny Home Manager, this setting is only possible under Complex configuration.

Each device that is to communicate with the Sunny Home Manager via a Modbus communication protocol must be uniquely addressed.

On the tab Modbus configuration, you can store up to 4 different Modbus configurations with which the Sunny Home Manager searches for connected devices. After a successful search, the detected devices appear on the tab Overview new devices and can be added there.

Procedure:

  1. Select Configuration > Device overview in the page and menu selection.
  2. Select the device properties of the Sunny Home Manager.
  3. After selecting the Extended configuration view, open the tab Modbus Configuration.
  4. In the Modbus Profile column, select the required predefined Modbus device from the drop-down menu.
    If a Moxa device is used with an SG-ready device, for example, set up a Modbus configuration with profile MOXA1214.
    If a ripple control receiver is connected to the Moxa device for external limitation of the active power feed-in, use the profile MOXA1214_PLimit.
  5. Enter the data of the selected device in the fields IP address, Port and Unit ID.
    If the Modbus device is a Moxa device, it is recommended to set the Moxa device in the router with an IP address/MAC address binding or to subsequently set to a fixed IP address from the free range of the router not used for DHCP. Port (default 502) and Unit ID (default 1 or 2) do not need to be changed.
    Existing entries can be changed by overwriting.
    To delete a configuration, click on the recycle bin symbol in the corresponding line.
  6. Click on [Save].
