6.2 INTERFACING WITH THRID PARTY APPLICATIONS
Creating script is possible to retrieve data from the SOLYS 2 via the Ethernet port TCP/IP 15000.
The SOLYS2 sun tracking application has its communication interface on TCP port 15000. Note
that it can only handle one connection at a time on this port. In case of a new connection
request, the existing socket is disconnected. Note that the web interface of the SOLYS2 also
uses this TCP port to control the sun tracking application. Therefore, do not use the web
interface and direct communication to the TCP port at the same time. Also, do not
communicate directly with multiple applications to the TCP port. This may lead to unexpected
behavior.
Commands, replies and checksum
All commands listed on the Commands section of the web interface may be issued via the
communication interface of the suntracking application. To ensure proper transfer of data, a
checksum must be added to every command according the following algorithm (C code):
