Regards

Otherwise, you also can use the "normal" TCP/IP communication and the T-blocks, For I-device, look here https://www.automation.siemens.com/mdm/default.aspx?DocVersionId=63972520715&Language=en-US&TopicId=62565472779 it is a good step-by-step comfiguration. As transfer area, you must configure 4 byte input "I"(->), and 4 byte output "Q" (<-).

Pittiplatsch Posts: 1368 Rating: (128)	Hello, in TIA, you insert two plcs. In one PLC, go to the properties of the PN-interface and then to "operating mode". Here, choose" io-device" and as "assigned IO-controller" the 2nd one. If you have 2 different TIA projects, you also go to the properties of the PN-interface and then to "operating mode". Here, choose io-device and create a GSD. This GSD must be insert in the other TIA project... After activating "io-device", you can insertnew transfer areas. Click "new" and choose the direktion "-> means "from the IO-Controller to the IO-Device"; input ") and the size (4 bytes). Click "new" and choose the direktion "<- means "from the IO-Deviceto the IO-Controller"; output ") and the size (4 bytes). Thats it. Look at the link, i posted before. There is a good instruction....

For (a lot) more information on the subject, please download this little manual from PI International, the Profinet System Description, and examine the screenshot below.<https://www.profibus.com/index.php?eID=dumpFile&t=f&f=51714&token=4ea5554cbb80a066e805a879116ead2a759c23c3 Hope this helps, Daniel Chartier Attachment Profinet IO Controller and IO Device.jpg (441 Downloads)
