Translate Siemens Step5 program to Step 7

[gConejo]

Hello Everyone! I just became a member of this great site.

I have a PLC program from an S5-100U PLC, and now I want to make a PDF report of all Blocks and Functions of the PLC in LAD lenguage. I found that the proper way was to convert the S5 PLC program to S7 and then translate from STL to LAD. And everything was converted from STL to LAD well so far, but some of STLs were not converted.

For example the next STL could not be converted to LAD, does anyone know what do I have to correct in this code in order to be translatable? I'm not good at STL language... Any help is appreciated. Thank you!

L #MIN
L #_REAL
>I
JC M001
BEU
M001: L #MIN
T #_REAL
L #MIN
L #_REAL
>I

See below... I think the last 3 lines of your code are pasted in duplicate, but I put them in as the last instruction on the right anyway.

PS: BEU is "block end unconditional"

But if this is the entire block, you don't really need it (if the last 3 lines are pasted in error.

IF you do need the BEU... make a JMP to the end of the function or function block,

I made the opposite of >I which is <=I to jump to a label which is at the end of the block. The MOV _REAL to _REAL is just a "placeholder" logic because the rung can't be empty.

Wow..!! Thank you SigmaDelta.

Your last post did work! Now I have my file ready to download. As you said, I repeted the last STL code line. Sorry about that.

Thx again!!
