Table 11 Task details for example 1
In the first task ("Prog1"), the "progtes(1)" program uses input IX4.0 of input
module 1 and input IX6.0 of input module 2. Before the first task ("Prog1")
starts, only these inputs will be updated.
In the second task “Prog2” the input IX4.1 of input module 1 is programmed
in the program “progtes(2)”. The input of this input module is updated before
the 2nd task ("Prog2") starts.
