Timers :

They are installed like ordinary actions by choosing the timer function.

Start or stop, (Stop sets to 0 the current value).

When a timer is running, passing from one step to the next step does not stop the timer ; the timer keeps running.

The time basis for operation is the tenth of a second.

 

Counters :

Choose the type of operation (+, -, to position, RAZ) before to place the counter in the action window.

 

Conditional action :

In the chosen example, the action Q4 is true only if step 2 is active and I1 is true.

 

The placement of this condition is done from the window of the conditions associable with the actions.
