Modbus

8.9.1 SMA Modbus Profile
Connected Modbus devices can be used, for example, as energy meters for generation and
consumption data at the grid-connection point 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.
8.9.2

SunSpec Modbus Profile

The product supports the standardized SunSpec Modbus profile via the interface of the Modbus
