RS 5000: Use OneShotRising in ST?

[theColonel26]

I am using RS 5000 v30. I am trying to use the OSRI AOI to detect a Rising Edge.


OSR_EnableACC is of Type FBD_ONESHOT


EnableACC is what I want to detect the Rising Edge on.



Here is my Code

OSR_EnableACC.InputBit = EnableACC;

OSRI(OSR_EnableACC);

IF OSR_EnableACC.OutputBit Then
    //Do Somthing
END_IF;

I am getting a

Error: Line 1, ';': Unexpected.

I'm not well versed on Rockwell's structured text, but if it follows IEC61131 then you need to use := as the assignment operator.

OSR_EnableACC.InputBit := EnableACC;

that was the problem. It's been awhile since I used ST.


I forgot about it's weird PASCAL like syntax.


Thanks

Curious - why not DIY:

if (condition & not OneShot) then
   // do something
end_if;
OneShot := condition;

Well I have done that in the past, and might still do it. But I am trying to reinvent the wheel less.


AB doesn't have plain User Defined Functions does it? Just FBs aka AOIs.


I'm gonna start a new thread about Functions.
