The virtual slave interface enables a second virtual device (slave) to be created on the same hardware interface. This enables the user to exchange more data with a PROFINET controller or to establish a connection to a second PROFINET controller.

Since the ports X101 and X102 are switched via the hardware and only possess a real MAC address, that of the virtual PROFINET device is editable and the user himself is responsible for ensuring that these MAC addresses only occur once in his system. The IP address is assigned by the PROFINET controller and cannot be registered in the operating system. This means that non-PROFINET services such as ADS, CERHOST, etc. do not function over this IP address.

	Pay attention to the system utilisation rate (to be observed only when using the virtual device interface) Each PROFINET or Ethernet device that is connected via the switch of the CX8093 increases the system utilisation rate. The number of devices that run via the switch should not exceed 25 (the devices in the other direction must also be counted)!

PROFINET name and IP address

The DIP switches cannot be used directly for the resolution of the name. However, the PLC can read the address switch and link the name via the Generate Station Name from Control function.

No name
Name with DIP switch (only indirect)
Name by the System Manager
Name by the PLC program and System Manager

Device settings

Virtual Device Interface 2:

"1" second, virtual PROFINET device
"2" Editable MAC address, only the last byte is editable.

Generate Station Name from Control

With this an extension of the name can be assigned via the PLC program. The extension consists of a three-digit numerical value. To do this, link the PnIoBoxCtrl with the PLC program. The value must be registered as a constant value and must be available when starting the PLC program. For example, the address of the switch can be read and thus the name of the device formed with the function F_CX80xx_Address.

Example (ST):

Address:=16#FF AND INT_TO_WORD(F_CX80xx_Address(8093));
PnIoBoxCtrl:=Address;

Get Station Name from Tree

This means that the name of the PROFINET device will be taken from the System Manager tree.

Register PN IP settings not at the OS

Not possible with the virtual PROFINET interfaces.

PROFINET State

Virtual Device Interface 3:

If you link the PnIoBoxState variable with your PLC program, you can monitor the state of the PROFINET controller with it. The state 0x0005 is the error-free state, i.e. the master is in data exchange with the device (i.e. the CX8093).

0x0001 = Device is in I/O exchange
0x0002 = Device is blinking
0x0004 = Provider State -> 0 = Stop, 1 = Run
0x0008 = Problem Indicator -> 0 = OK, 1 = Error

	No programming via the virtual PROFINET interface The CX8093 cannot be programmed via the virtual IP address. The ADS functions or other non-PROFINET services are not supported by the virtual PROFINET interface.
