SMA Modbus Profile
Connected Modbus devices can be used, for example, as energy meters for generation and consumption data at the point of interconnection or for energy monitoring. For this, predefined Modbus profiles, user-created Modbus profiles or the SunSpec Modbus profile must be used. The Modbus profiles will then be assigned to the Modbus devices.
IP addresses of Modbus devices
In systems with Modbus devices, static IP addresses must be assigned to all Modbus devices. Suitable IP addresses can be assigned to the Modbus devices from the free address supply of the network segment either manually or dynamically via DHCP.
If the IP addresses are to be assigned dynamically, DHCP must be activated in the Internet router (see the Internet router manual). Make sure that the Modbus devices do not contain variable IP addresses but always the same IP addresses (static DHCP).
This also applies to Data Managers that are used as subordinate devices.
If IP addresses of Modbus devices have been changed, all devices must be restarted.
