If you look at the help file for a function / instruction that you would like to use, you can see the ST layout for that item.  See below:

Just copy that text and paste it into your structured text and modify.  You could end up with something like this:

I just noticed that I gave you an answer for Sysmac Studio.  Please ignore the above answer....

For CX-Programmer, type ahead works in the structured text environment.  The type ahead will show you what each field is expecting:

So, you end up with something like this:

Make sure to declare all of the variables that you are using in the structured text block as I have shown above.  I declared I00 as a global since your code did that.

Thank you so much Wash.

When I want to use another TON with different PT , do I need to declare another  function block with different instance name or can I use that FB above , only need to change the value of T , and the condition of IN

You would need to declare another instance of the FB.  You could use the TIMER function however.  Functions do not require instances.

Thank you Walsh again. By the way, this problem is not related to the topic; but do you know how to clear an event in event history.

Hi Michael Walsh,

I had a question about using timers or counters in structured text. I did declare the timer in the external section. I did try it declaring it in internal. I always end up getting the same error. I suppose you will be able to help me with my question. Please see the attached screenshot of my program and errors.

code :TIMX(A, TimerNumber, 500);

Declaration:TimerNumber    TIMER                            INTERNAL     0    0    
 

ERROR: Symbol 'TimerNumber' is the invalid data type(TIMER or COUNTER) in the SFC/ST program.
 

Thanks

I am not having any issues.  If you post your code here(.cxp file), I can look at it to see if I can tell what is wrong.

What is the model number of the PLC you are using? CJ2M, CP1L, CP1E............................

Structured Text timers or Counters can ONLY be used with CS/CJ series CPU units version 4.0 or later, or with CJ2-Series CPU units.
