Download datalink setting to cqm1h cpu51

[Abolfazl]

Hello friends I have worked with other series of omron plc but this is the first time I am working with cqm1h cpu51 series. In a factory, 4 of these PLCs exchange data with each other with a clk21 card. After a problem with one of the CPUs and replacement, I was never able to download the datalink settings. I did all the steps in the manuals step by step but I did not succeed. In cx-net software, after selecting online, I selected the data link menu, but as you can see in the attached image, the setup button is never activated. Thanks for guiding me
