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 router (see
the 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.
Communication disturbances in the local network
The IP address range 192.168.12.0 to 192.168.12.255 is occupied for communication
amongst SMA products and for direct access to SMA products.
Communication problems might occur if this IP address range is used in the local network.
• Do not use the IP address range 192.168.12.0 to 192.168.12.255 in the local network.
