Flash
This block creates a 1Hz and a 4Hz waveform at its outputs. It can be used to switch an output on/off (e.g. a fault output)
cyclically.

Signal Name
In, PT: In and PT are input variables of the Boolean and Time types respectively. If In is
logical 0, Q is logical 0 and ET is 0. As soon as In becomes logical 1, the time will begin to
be counted in multiples of 100 milliseconds in ET until its value is equal to PT. It will then
remain constant.
t#1H15M22S 1 hour, 15 minutes, 22 seconds
t#1H 1hour
t#10s500ms 10.5 seconds
Internally the delay time is represented as multiples of 100ms.
The max. possible delay time is 1h49m13s500ms.
If PT is left open the delay time is set to zero.
In online mode the output ET (W) shows the remaining delay time in
multiples of 100ms.
Q and ET are output variables of the boolean and Time types respectively. Q is logical 1
when IN is logical 1 and ET is equal to PT. Otherwise it is logical 0.
