32�5 Digital Interfaces
Solar-Log™provides two interfaces for exporting the current data.
The data is updated every 15-60 seconds.
WARNING
The following descriptions for two interfaces are intended for users with a tech-
nical background. Solare Datensysteme provides these interfaces without any
guarantee and with the exclusion of any legal liability.
We do not offer any telephone support for these two interfaces.

32�5�1 Modbus TCP
The software interface function allows external systems to have access to internal data on the Solar-Log
™. The interface has been designed so that live data can be retrieved. The function is available for every
Solar-Log™ with the current firmware version.
The interface cannot be used to configure the Solar-Log ™ and the devices connected to it. The entire con-
figuration is carried out via the Solar-Log ™ Internet browser interface.
Modbus TCP Port: 502
