Dimming output
Description
The relevant output can be switched on gradually in this mode. The dimming output is
activated by means of the output process data. The dimming frequency is 100 Hz. The duty
factor increases linearly from 0 to 100%. The output is fully ON when the dimming time
expires. Dimming is activated when the output is switched on. When the output is switched
off, it is deactivated instantaneously. The dimming status can be read in parameter Dimming
Status. The possible values of this parameter are "Deactivated", "Active" and "Expired". This
function is used primarily to gradually illuminate LED modules.
Parameters
● Dimming time
● Inverting output
If "Inverting output" is deactivated, dimming activates a rising edge in the output process
data. When the parameterized dimming time expires, the output is activated. If the output
process data are deactivated, the output is OFF.
If "Inverting output" is activated, dimming activates a falling edge in the output process
data. When the parameterized dimming time expires, the output is activated. If the output
process data are activated, the output is OFF.
