Uploaded program not possible to be downloaded?

[Vadagor]

Good morning guys!

I have a doubt. I uploaded a program from a S7-200xp on the field and took it to the office. Before doing any test I tried to download it to a S7-200 we have here. To my surprise, it gave me errors, and didn't download.

Specifically, it has a "Double Integer to Integer" converter with an output to an analog output port. I read the manuals and that port seems to be uncompatible with that block. So, my question is: "how is it posible to have it configured, and working, on the first PLC, if the manual specifically says it can't have that port assigned to the block output?" I know that it is not exactly the same PLC (the first one has an "xp" at the end, but I only saw differences in the registers quantities; there is nothing talking about blocks functionalities).

I'm scared because, even when it says that it is a "Non Fatal Error", the PLC is totally erased at the end of the download process...

Any idea?

Thanks in advance to everyone!!!

Nick.

What is the CPU version number in your project, and the CPU version online?

I am not sure if it applies to Siemens, but I found some programming errors in an Allen Bradley PLC5 that never would have verified and been downloaded - but if you did them through an online edit it would put it in the program and run it. Specifically this was a few shorted branches around XIC instructions instead of using an Always On bit on the branch.

I could do online edits to the program, but when I tried to do offline edits to download RSLogix5 would not allow it.

I don't have experience with this particular PLC, but with various brands and models, I have found that the specific processor type specified in an offline program file must match the equipment to which the program is being downloaded.

For instance, I recently replaced a failed GE Series 9030 Model 364 processor with a model 365. Before I could download the program, I had to change the specified processor in the offline file to match the replacement processor.

Thank you everybody for the responses. I did all the checks but still have this problema.
Is there any way to tell if the standard library was used? I mean: is it possible to have modified blocks with standard blocks names, and have an incompatibility there, as I don't have the modified versions?
Cheers,

Nick

It's possible your CPU in your office has a different firmware version than the one in the field.

Or... does it have a CN on the part number
