Converting S5 to S7

i have some problem on converting s5 (CPU 115u 943B) to s7-300.
anybody can help me to explain the S5 code?
here is the program,

My speculation is that the program is used to store a pointer of Counter/Timer/Flag/PI/DB/PQ to FW224 . is that right?
but i dont understand some codes then i cannot write S7 program.
Anybody can help me? Thanks.

ps: sorry for my bad English.

You have dug up some really strange coding.

I see two plausible uses:

A: It's a 'protocol overlay' to a communication driver.
Is there a call to FB SEND or RECEIVE in connection to this?
Could it be some Applicom communication coding?

B: It's a 'home made' command interpreter.

Kalle

No FB SEND and RECEIVE call. I've removed that from converted S7 program.
Just this block that I do not understand and unresolved.

Are there no comments in the S5 code ?

You could try to investigate what calls this code, and when it is called. That may give a hint to what it does.

No comments in S5 code. this is uploaded program.
I just want to know how to create pointer in s7 based this code.

:L KH EF00 ===> Peripheral Input?

am I right that above code is used to create pointer to FW224???

Yes, it makes FW224 to point to a certain address area.

Of curiosity: IS it a code bit from a communication interpreter?

Kalle

hhmmm,,, I don't know what the meaning of 'communication interpreter'.
PLC only connected to HMI. no other connections.

What about this ?

This is the code that call FB159 (my 1st post)

As I know, FB159 is only called at certain times only. Am I right?

I think you are putting much effort into translating a piece of code that isn't usable in Step7.

Which cards are used in your rack(s) and what are their IO adresses? Which pheripery address is assigned in PERA?


Kalle

I'm with Kalle on the communications interpreter thing. You mention a HMI, which one? you still use it on the S7 set-up?

@Kalle
PERA = 200

@Wimpie
original is OP73 (S5)
replace with OP177B (S7)

The name "COPY" does indicate it has to do with copying something, and the code seems to indicate that the copying dynamically adjust to what data type that is to be copied.
My guess is that it has to do with saving actual values for backup and restore purposes.

This thread shows the problem of attempting to migrate old S5 code without having the commented source. You can only migrate so much. You will reach stumpling blocks where it becomes guesswork to figure out what the old uncommented code does.

If it was my project, I would ditch the old code and start all over. I would determine what the machine or process does, and how I would want it to function. Then I would write a completely new program based on that. Have done it several times for small and big upgrade projects.

well a little googling brought up this link about S5 and panels over profibus.
it lists this blocks:

Windows-based operator panel:

FB158 -- Protocol processing
FB159 -- Copies data to/from the memory
DB58 -- Free DB, main memory for FB158 (free DB with 11 data words in length. This DB can be used by the user from the eleventh data word.)

Well like Jesper said, forget about these blocks. You can't use it anyway since your new HMI will be working differently.
