why cannot the timer be accessed by #heads[#i].timer(IN:= true, PT:=T#50ms); ...

William Ratcliffe

Thanks for the response.

Its a general quesiton I suppose; I have a struct defined that encapsulates all the elements of a machine 'function', including a timer.
I now have an array of this struct to define all similar points on the machine.
I loop through the array processing each in turn.

So the question is still why cannot it be accessed by

#heads[#i].timer(IN:=true,PT:=T#50ms);
or
#heads[#i].timer.TON(IN:=true,PT:=T#50ms);

I would not want to define the timer elsewhere (as a global for example) as the proper place for it from a encapsulation point of view is in the struct or UDT. (sorry I'm a computer sci grad)

... Passing it to a FC function is fine. I was just wondering
