We need to access and go online on a CPU1515 connected to the x150 port of the D455 profinet. Do we have to do any special settings for it to work? Will we be able to also access other devices connected to the plc? 6AU1455-2AD00-0AA0 , 6AU1400-2PA23-0AA0-Z M44 6SL3040-1MA01-0AA0 , 6SL3054-0FB01-1BA0 6ES7515-2AM01-0AB0 6AV2124-0QC02-0AX1 6AV3688-3AY36-0AX0 6ES7155-6AU01-0CN0 6ES7138-6CG00-0BA0

	Searching for Siemens used/new equipments ? Take a look here : https://www.ravettiautomation.com

Will this stop the Simotion ? (because the machine is running) ChristophD yes please create a subnet on the x127 port and download this to the simotion.
