L Series CPU Program Transfer

[Maher Salem 0]

I'm facing a problem with L Series PLC

when i replaced the CPU, I read the whole program from the old CPU

But, when i write it to the new CPU, the Attached message appeared

What is the Solution to Transfer all the Program correctly

Is it the same CPU model?  Did you do as the message indicated?

yesit is the same model but i don't know where is the place to modify these default parameters

Hi, had the same problem some time ago,

for me following solution worked:

1. clear plc memory
2. upload only Parameter, no program files
3. reboot plc
4. upload program

 

hope this will help

i will try this

Better have a backup of your project if you go clearing PLC memory.

i have a cpu containing the original project, and i have another spare cpu, 

the main problem appears when we write the program to the new cpu

the simple motion module error LED is flashing and the machine isn't working well

So, i want to know an ideal and safe method to replace the cpu without affecting the setting of the intelligent function modules (Motion and temperature)

especially during the (Write) process

hi,

here are some thoughts:

- you can read and later only download the parameter of the simple motion module without affecting
  the parameters of the other intelligent function modules, therefore inside the read from plc dialog
  deselect all checkboxes except for the parameter of the simple motion module. Then use the 'detail'
  button on the right side to select which parameters from the simple motion module should be read or written

- attention: only WRITE the Simple Motion Module Parameters if you use a (second) simple motion module.
  If you only replace the cpu-module (connecting the new cpu module to the 'old' simple motion module) you
  should NOT WRITE the simple motion module parameters! If you use a second simple module and write
  the parameter also be sure to select the 'write to ROM' setting inside the 'details' setting, otherwise the
  parameters will be lost after power off.
 
- you can use the 'MR Configurator' Application to get further information about the error from the
  simple motion module. Also you can check if the simple motion module is properly setup.
  if you have the servo settings (*.mr file) you can open it inside the mr configurator application.

Make sure when uploading from the old CPU that you include the intelligent module settings in the upload.  Then when you do your download to the new CPU, the settings in the intelligent modules should match.

I have not touched an L Series in about 7 years, don't the motion module settings have to be transferred from a different utility?

Mr. AndreasW

your Conclusion is the nearest to my thoughts

i have only one simple motion module

the only part will be replaced is the CPU

So, Its Important to read your comment before trying to write

My wrong thoughts is that the module away from uploading and downloading (Don't contain a memory) and only the CPU is the place to store all data

So, i will try to Write the program and parameters then see what will happen

thank you
