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.
This also applies to data managers that are used as subordinated devices (slaves).
IP addresses in local networks
In local networks where no DHCP server is active, proper IP addresses must be assigned from
the free address pool of the network segment to all network participants to be integrated
during commissioning.
If the IP addresses in the local network are to be assigned dynamically, DHCP must be
activated in the router (see the router manual). The DCHP server automatically assigns the
appropriate network settings to your nodes in the local network. A manual network
configuration is therefore not necessary.
Completion of data after interruption of communication
If the data communication between the Data Manager and SMA products connected via
SMA Speedwire is interrupted, the data will be retrieved subsequently for the time of the
interruption. Data is retrieved with a maximum interruption period of 7 days. Existing data of
newly connected SMA products will not be transmitted until the Data Manager is
commissioned. Historical data of SMA products are only available in the user interface of the
SMA product.
Possible causes for the interruption of the data communication can be:
• Interruptions of the SMA Speedwire connection
• Resetting connected SMA products over a period of several hours
• Voltage supply interruption
