The MDT Logical Module is used for fast and easy compilation of logical functions to control building automation systems. All the functions are parameterized directly in the ETS without additionally software tools. There are 24 independent function blocks with arbitrary functions available. For each function a description can be stored in the ETS. The 4 LEDS on the front panel can be controlled optionally by objects. According to date, time and location the Logical Module calculates sunset, sunrise and twilight. Additionally there are output objects available for summer/winter time, calendar week, day of the week, every hour, every minute, day/night.
