BASPro is a programming software package suitable for building automation application, perfectly integrating with BAS-3500 Series DDC Controller (Direct Digital Controller). BASPro features rich function blocks like mathematical calculation, data conversion, logic operation, alarm, event and timer, and control algorithm (PID, Ramp, ON/OFF switch control). Moreover, BASPro also provides many BA domain function blocks, such as scheduler, HVAC calculation and sequential control, which are commonly used in building applications. Developers can benefit from saving development time by the function blocks. Engineers can develop applications on their computer. After the application program is complete, it can be download to the BAS-3500 series through Ethernet. Then BAS-3500 series becomes a standalone controller since it can execute the program by itself. Besides, BASPro delivers simulation function that you can observe the program execution situation before the program is downloaded to the BAS-3500 series.
