Table 3-3 Options / Input Areas in the “PROFINET” Tab
Option / Input Area
Meaning / Effect
 Mode Depending on the type of CP device, you can select the possible
modes here in which the S7 station can be operated on PROFINET.
 PROFINET IO Controller
With this option you decide whether or not the Ethernet CP is
operated as a PROFINET IO controller.You can also make this
setting by assigning a PROFINET IO system to the CP in HW
Config using the context menu.
 PROFINET IO device
With this option you decide whether or not the Ethernet CP is
operated as a PROFINET IO device. In a further step, you will
also need to assign the CP to the PROFINET IO system as a
PROFINET IO device.
 Device Name Name of the device (according to DNS conventions). The device
name must be unique on the Ethernet subnet. If the CP is operating
as PROFINET IO controller, the device name is derived from the
short identifier.
STEP 7 gives you the option of adding the name of the IO system as
part of the device name automatically. To use this feature, select the
option ”Use name in device/controller” in the properties of the
PROFINET IO system”.
 CBA communication To be able to use the S7-station with PROFINET CBA, specify the
CP to be used for the componentization for PROFINET CBA or
SIMATIC iMap.
