This is the second episode in a series of various Codesys articles using TURCK’s TBEN-L5-PLC-11. This time, the Profinet IO Controller is set up on the TBEN-L5-PLC-11 and connected to the TBEN-L4-8IOL, also from TURCK.
Let’s enjoy FA.

PROFINET IO device model…
The technical properties of PROFINET IO devices are defined by the device description file, the GSDML file.
A PROFINET IO device consists of 1 to n slots and can also contain 1 to n sub-slots. A sub-slot is a placeholder for a sub-module, which establishes an interface to the process. Submodules can contain parameters, data and diagnostics. Slot 0 is always reserved for a device access point (DAP); the DAP has a physical interface to the Ethernet network and represents a device.
Other slots and sub-slots represent other device functions. This structure is defined by the field device manufacturer. Not all slots and sub-slots need to be associated with a physical function. The allocation of slots and sub-slots and the assignment of functions (e.g. operating mode, diagnostics, etc.) is done by the PROFINET controller’s configuration software.
This device model allows manufacturers to design modular and flexible distributed field devices. Users can flexibly configure distributed field devices.
Implemenation
Cofigure Mode
To distribute IPs from the Profinet Controller to the TBEN-L4-8IOL, set the Addressing Mode to PGM-DHCP mode.
PGM-DHCP mode 600 In PGM-DHCP mode, the gateway sends DHCP requests until a fixed IP address is allocated; the DHCP client is automatically deactivated when an IP address is allocated to the gateway via DTM or web server. DHCP client automatically deactivates when an IP address is allocated to the gateway via DTM or web server.
To set PGM-DHCP mode, set the Rotary switch to 600.
Download GSDML File
The Profinet device is the TBEN-L4-8IOL, also from Turck, so download the TBEN-L4-8IOL GSDML File from the HP.
Install the GSDML File
To install the GSDML File from the Codesys IDE, click Tools>Device Repository.
Click on the Install button.
Select the TBEN-L4-8IOL GDSML File that you have just downloaded.
Done!The GSDML File is now installed in Codesys.
Configure Profinet Network
The next step is to build a Profinet network.
Add Ethernet Driver
Add an Ethernet Adapter: deviec>right-click>Add Device.
Select Ethernet Adapter>Ethernet and proceed with Add Device.
Setup Adapter
An Ethernet Adapter has been added, but Turck’s TBEN-L5-PLC-11 has two Ethernet Ports, so configure the Adapter to be used as a Profinet IO Controller for Codesys.
Click on Ethernet>General>Browse.
Configure the Ethernet Adapter according to your application.
Done!
Configure Profinet IO Controller
Next, add the Profinet IO Controller. Right-click the Ethernet Adapter you have just added>Add Device.
Select Fieldbus>PROFINET IO>PROFINET IO Master>PN-Controller and add it with Add Device.
Done!Now that the PROFINET IO Controller has been added, configure the automatic assignment of Profinet IO devices in General>Default Slave IP Parameter.
In the diagram below, the initial Profinet IO device has an IP address of 192.168.13.200 and then 55 nodes up to 192.168.13.254.
Configure Profinet IO Devices
Now add the TBEN-L4-8IOL. Right-click the Profinet IO Controller you have just added>Right-click>Add Device.
Add TBEN-L4-8IOL.
Done!Set the Profinet device name and IP address in Station Name to match the application.
Login
You can configure the Device name and IP address of the Profinet device in the Codesys IDE. To do this, first download the Profinet Stack from Codesys to Runtime once.
Proceed with Yes.
Done!
Scan for Devices
Next, click Profinet Controller>right-click>Scan for Devices.
You should be able to find TBEN-L4-8IOL, so make sure that the Station Name matches the one you have set for your project.
Change the Profinet Devices Slot
Now right-click on the relevant Slot > Plug Device to change the settings for each Port.
Select IN 8 BYTE/ OUT 8 BYTE (Octet) and click >Plug Device.
Done!The Port setting of Slot 1 has been changed.
The TBEN-L4-8IOL can be built as a DIDO as well as an IO-Link.
Diagnostic information and other information can also be obtained via Profinet, so you can add devices, such as Diagnostics slots, according to your application.
