native DigOut_Init(digout, mode, cfg1 = -1, cfg2 = -1);
Initialises the isolated switch contact (NO, CC). The mode is selected via the "mode" parameter. The
meaning of the "cfg1" and "cfg2" parameters is dependent on the selected mode. Detailed information
on the isolated switch contact is provided in chapter "Isolated switch contact (NO, CC)" on page 61.
Note: Using "DIGOUT_FREQ" (Frequency output) and "DIGOUT_PWM" (PWM output)
modes drastically increases the energy consumption.
Parameter Explanation

Only a multiple of the sample rate for the universal inputs selected via the "UI_SetSampleRate()"function can be
set for the pulse duration in "Pulse/min." mode. The actual pulse duration is calculated as follows:
Pulse duration = (cfg1/sample rate

+ 1) x sample rate
