Problem with Allen Bradley Micrologix 1500 PLC

[BIGEYE]

While trying to go online to a Mirologix 1500 using RSLogix 2.50, at the end
of uploading processor image I get an error Upload Failed - Decompiler
Error.
As a result I cant go online to view/edit the programmable controller
program.
There is something on the Rockwell website concerning this but I think you
need to be online to fix. Unless there is another way.
Anybody can offer any assistance.
TIA

Are you using a 485 cable to connect? If so
Check your cable that your using to connect to the processor.

Can you change areas of the program and just view the processor?

Last resort which may be a option or may not. Cold boot the processor DO NOT
remove the processor. I am not sure if this one uses EEPROM to write the
program to memory. Most do I would hate to give you information that causes
more problems than it solves.

That should have been RSLogix 5.20

The website says
Error:
Decompiler error / unknown error when trying to upload or go online with a
Micrologix 1500.

Cause:
Empty Datafile in the project.
RSLogix 500 3.01.09.02 will not upload a project that has an empty data
file.

Workaround:
Upload the project with RSLogix 500 ver 4.0 or later. Open the suspect
datafile and expand it to at least one element. Save the project and
download to the processor.

But I am using version 5.20 and still have this problem.

I don't have a solution to your problem. But, just to clarify, you are
using RSLogix 5000 and not RSLogix 500, right? The error message that you
posted says RSLogix 500. The Micrologix programs with RSLogix 5000.

Nope. The RSLogix 500 programs the Micrologix.
