23�4 Linking (only Solar-Log 1000 and 2000)
The linking function is to be used when there are not enough interfaces on one Solar-Log™ or the cable
lengths between the Solar-Log™ and the various inverters exceeds the RS485 specifications.
The link between the data loggers is established with an Ethernet connection. This TCP/IP connection can
be established with various technologies such as fiber optics, wireless LAN, radio relay. For the Solar-Log™
network it is only relevant that the connection is fast and reliable.
The master within Solar-Log™ network always has to be a Solar-Log 2000 PM+. The Solar-Log 2000 can
be used as the slaves.
The link is used to exchange control commands and responses between the Solar-Log™ devices.
Each Solar-Log™ has to transfer yield data itself to a server.
Procedure:
•
Select configuration from Configuration | Special Functions | Feed-in Management | Networking
•
Enter the IP address of the first slave.
•
Click next to the box with the mouse.
•
After entering the IP address an additional input box appears.
•
A maximum of nine slaves can be active inside of a network.
•
SAVE settings.

If there are no inverters connected to the master in the master/slave mode, the plant
parameter under Configuration | Special Functions | Feed-in Management | Plant pa-
rameters and forecast value under Configuration | Plant | Forecast have to be set to 0.
