THis is my first week Programming PLC's and i'm working through the First Steps with CoDeSys.
It all seems to go fine until i try to Build the Project, which brings me up multiply errors with the same code,
Error 4024: PLC_PRG (4): Expecting ":" before "2" as an example.
Now im using the latest software and the instructions are Dated 2004.
I imagine the software has been updated numerous times since the instrutions where last updated.
Could this be where its all going wrong?
Any help would be much appreciated.

I am not quite sure which section you are getting the error on ("First Steps..."), but my first guess is you missed the ":" in an assignment statement ("x := 2;", not "x = 2;"). Also, possibly to missed a ";" at the end of a previous line. Goto the line of the code the compiler is complaining about and look at that line and a few previous to it. If you are using CFC, then maybe a wire is not actually terminating at an input/output on a function block.

This is my first attempt at writing a program, following First Steps.......
Following this guide, i get to the last step prior to creating a visualization, which is called BUILD PROJECT using the F11 key and that brings me up the 3 errors.
I have copied & pasted my lines of code.
PROGRAM PLC_PRG
VAR
Trig1: R_TRIG;
Trig 2: F_TRIG;
Timer 1: TOF;
Timer 2: TON;
END_VAR
What is CFC?
As for my timers,
I Have nothing connected to the ET outputs on both my timers.
And the 2 PT inputs are addressed as T#5s but have remained PINK. Is that normal?
Thanks for your help

Hi,
your declaration is not IEC compliant. Whitespaces are not allowed
Wrong:
Correct:
Thanks Singleton
I'll re-write and see how it goes
