I have a S7300 PLC And Trying To Connect It With CI840A
I Installed The GSD File For The CI On The Siemens PLC And Made Configuration For The CI 840A but the PLC Didn't See The CI The Message Shown On The PLC (Module Configured But Not Availabe.
More Information would be needed to help you troubleshoot the issue.
First check if you see the Profibus Slave (CI840) from your Profibus Master.
It should be possible to scan the Profibus Network from your Master and see all conected slaves. If the slave appears then you can start worrying about the gsd configuration and communication.
If you are sure that you have checked all of the configuration on both the AC800M and the Siemens S7 and also all of the cabling, then you need to see more detail about what is happening on the bus. You can use a number of analyzers, but this one is pretty good ..
If the "configured but not available" error is seen on the S7 then it sounds like the error is there. Are you sure you've correctly configured the port as a passive slave and programed the required function blocks to support the port ?
