Good Morning Everybody, 

I have a 1512SP1-PN Firmware V2.9.2 and the Version of TIA PORTAL is 18.0.1.0 . 

I had to connect the PLC to  2 Fanuc ROBOT by ETHERNET/IP , so I have used "LCCF_EnetScanner Library". 

In this Case my PLC is of course the scanner, and the 2 Robot the adapters and everthing is working fine,communication is ok and so on.

Now the question, in the setting of the adapters for both Robot I have put "packetInterval:30ms", so how long should be in the OB30 , where there is the call of the EnetScanner, the cyclic time parameter? 

Of course, with lower values of Cyclic time of OB30, cycle time of PLC will be higher, but which should be a correct setting of the OB30?

Hopefully I have been clear

Thanks everybody
