:confused: Hello ALL,
Firstly, I am a complete beginner in PLC's, so excuse me if the question doesnt make proper sense. I have a solution file which was working fine with the CX 9020 PLC. Now, I changed the PLC (CX 5130) but still running the same old solution. Now, the problem is, the variables links are disappeared and I think I need to link them again newly. My question, Is there a way to restore all the previously linked variable addresses? NOTE: the terminals and the connections remains same for both PLC's. Hopefully, waiting for cool positive reply. Thanks in advance.
 
If you still have the old CX9020 project with present links, you can export its terminals (right click on terminal and "Save <terminal Name> as..") and then Import them to your CX5130 project ("Insert existing item"). When doing this, TC will ask you if the links of the imported terminal shall be restored. You should process a complete rebuild of the CX5130 Project before.

Hi again,
Exporting and importing the terminals worked perfectly, but the LED's doesnt light up in the I/O terminals (EL1809, EL2809), all other stepper motor terminals light up. Trying to find out What could be the issue? Please help. Thanks in advance.:confused:
 
The two terminals you are mentioning are HD-terminals and these terminals have a different LED setting then the standard terminals. The HD terminals only show the state of the inputs or outputs, so as long as you didn't set an output to true or any input is high no LED will light up.
 
Can you please help me with some documentation on OP states? I couldnt find the detailed ones. I am a complete beginer. This is what I have found. the WC online state value.2.JPG1.JPG

As to be seen in your screen shots, WcState=1 means invalid data from the slave, while its status is "Init" and "slave not present" which will be the real cause for your problem. Please go to "Device 1 (EtherCat)", open its online view and send a screen shot of it to give an overwiew of the general state of all slaves.
 
How do I make the transition from INIT to OP, tried to understand the documentation but couldnt. (I just need to make some changes in the code as a initial part of my master thesis), but unable to connect to the PLC completely. In the realtime, I isolated the CPU cores initially, but now when I click on read from target, it shows only one core. set on target is not available anymore. Is this the issue I am facing? Help please. Thank you.
 
Now, the PLC connection gives an error. Doesnt even switch to config mode. The leds are green completely. A new led FB1 also lit up now (previously not). Tried reconnecting but the error still remains.

OK, that sounds like you have choosen the wrong network card for your terminals, it seems to me, that you have choosen one of the two network cards on the left side of the controller as an adapter for your master. The EtherCAT bus normaly don't have an IP. Could you make a screenshot of the adpater setting of the master please.
 
I don't know what has been going wrong there. Maybe you should start with a new empty project and try to connect to the PLC with it. Then scan the IO to make sure all terminals are found. At last import the items of the existing project step by step.

Too late. You should follow Oliver.tonns Suggestion first before starting at Point Zero.
