Profinet communication AC800M and Siemens S7-1511C
I have a problem with profinet communication between CI871 in 800xa 6.0.1 (PM866) and Siemens 1511C.
I am able to establish the communication.
I use the S7 as I- Device. I exported the GSDML file to Control Builder M. After download everything is fine! But after disconnect the network – cable, the communication could not reconnect again!
when I use instead of the CI 871 IO controler an other S7 everything works fine.
Can anyone give me tips how to fix this problem?
I m not sure with the above suggestion but it may also a reason for communication failure.
