used for entering your longitude and latitude in order to calculate the solar altitude appropriately to
your geographic location by the function
sun
(), as shown on page 150. The coordinates have to be
provided also for the functions
azimuth
and elevation
(page 150).
After exiting the above dialog, Enertex
®
EibStudio creates a section [
Location
] in the user program
and writes the specified values. If this section does not exist, the Enertex
®
EibPC takes the default
values as coordinates 11 ° 3' 29" E, 49° 43' 11"N; as decimal: 11.07 and 49.68.
Example:
[Location]
// Longitude and latitude of the installation location
49.0722222222222
11.06888888888889
After the change of the data and the start of the user program, the Enertex
®
EibPC calculates the
sunrise and sunset as well as the position of the sun again. This process may take several minutes
to complete and is indicated when you connect with the Enertex
®
EibPC.
Please note that during this time the Enertex
