Hi all,

I have system using the Profinet, after i compile cfc with generate module driver, it pop out an warning message with no hard Found.after that i found the CH_AI block has no auto generate a gfreen line connect to the mode of the block(please refer CH_AI.JPG).after that i try to chacnge the CH_DI block with the CHDI with the Process Advance library CH_IO then it works.

1. what i want to know is that for Profinet system, we only able to use the CH_IO block from Process advance library? 

2.when i set up HW configuration, when i watch online it show grey at the module(see attchedment Hardware Config Online Screen Shot.png).but when i monitor the IO,I able to see the signal FB (see attchedment Monitor.Modify Screen Shot.png)

3. can any one provide me the procedure to setup the profinet IO topology?(PNIO Topology Online Screen Shot.png. )

any expert can help and provide me an solution?

thanks, appreicate
