Timer output
Description
The block works as a countdown timer which is decreased by 1 every PLC cycle. The timer initial value is
adjustable by the "Reload value" input. The timer is automatically reloaded with the initial value when it
reaches zero or it can be reloaded in any other moment using the "reload" input. The timer is held at reload
value until the reload input is deactivated. The timer output is inverted always when the timer is reloaded.

Input reload value can be constant or value from controller.
Note:
If you want the output to start at logical 0, tick First down option. Otherwise the output will start at
logical 1.
IMPORTANT: In case that inputs are not connected and First down option isn´t tick, than
output is active.
