Transferring parameters in binary to the higher-level controller

Hello guys!

I have seen signals received from the PLC in many posts:

DEFDAT

Decl int Carlength=1000
SIGNAL EXAMPLE $IN[1] TO $IN[16]

END

DEF Mainprog()

Carlength = Example_Func()


DEFFCT INT Example_Func()

;SIGNAL EXAMPLE $IN[1] TO $IN[16]

RETURN
ENDFCT

END

However, in this thread i would like to ask how should i send a value like 100 to PLC?

I think i have to "declare" signals as i wrote upper, but this time i have to use outputs:

DEFDAT

SIGNAL EXAMPLE $OUT[1] to $OUT[16]

END

However, i can't use RETURN in the function section to send to PLC the value, can i?

I hope you can help me guys!

Appreciate your help in advance!

Wow, i thought it will be a little harder!

Appreciate your help, it worked like it has to!

As an addition:

Your code in the first post doesn't work.

Can also be done very easy:

Declare properly scoped signal, for example by creating MyGlobals.dat

Code

DEFDAT MyGlobals PUBLIC

  SIGNAL EXAMPLE $IN[1] TO $IN[16]

ENDDAT

then in your program(s) use it as you like

Code

Code

Carlength = EXAMPLE

Display More

Hmm it's weird, cause it is working:)

The only thing what i missed is the EXAMPLE(what is the name of the signal) after return:

Return EXAMPLE

I will consider your idea and i will use it, cause it is more simply!:)

Thank you very much for your help!

Yeah..I missed it in this thread, but luckily not in the robotprogram:)
