5 Components/Software/ IP address used 1.2 Topology 1.3 Wiring IO-Link is a point to point communication (1 Master -> 1 Slave). In our example, we use port 1 of IO-Link master from CECC-LK. Festo has the NEBU cable series to connect to the IO-Link device and master. To get the correct wiring, please check the following pin assignments.

7 2 Configuring the IO-Link master 2.1 IO-Link configuration Download the IODD file of Balluff RFID read/write device and install it in the Codesys New an IO-Link master project, select CECC-LK and activate IO-Link Master You can either right click the port -> Plug Device to add sensor manually, I use port 2 here. Application Note CECC-LK as IO-Link Master connected to Balluff RFID Device and data carriers 1.10 Seite 7 von 17

8 Or right click the IO_Link_Master -> Scan For Devices And after a moment, you will automatically find the device Seite 8 von 17 Application Note CECC-LK as IO-Link Master connected to Balluff RFID Device and data carriers 1.10

9 2.2 Configuration of Parameters and Testing If BIS0103 is working properly, you will find the C/Q of CECC-LK is illuminated, and this read/write device s green LED flashes. Go to the BIS0103 IO-Link configurator, and activate the index column, you will see the parameters saved in Identification Menu and Parameter Menu. There is no description in the Balluff s IODD file, therefore, we get the description from manual. It is called SPDU in Balluff s manual.

10 The BIS0103 has 32 bytes output & input, which is very huge, it reaches maximum process data size of the IO- Link defined. You can read & write process data directly in Codesys. Description is again only available in the manual. To understand, for example, let us put a data carrier BIS0045 close to the range of it, and check the 1 st bit string. Seite 10 von 17 Application Note CECC-LK as IO-Link Master connected to Balluff RFID Device and data carriers 1.10

11 We can see the BB and CP is TRUE, the others are FALSE, which means device is ready and data carrier is in the read range of the read/write head. Application Note CECC-LK as IO-Link Master connected to Balluff RFID Device and data carriers 1.10 Seite 11 von 17

12 2.3 Programming in Codesys Program to read parameter by coding First we test the IOLink connection by the Function Block GetMode. Being noticed that we are using IOL port 2, but in this FB we should use port number 1! If the connection is OK, you get the return value True. We want the data carrier to send data once the data is in the range of BIS0103. This is controlled by the parameter Activity at Tag Present at Index In the screenshot, we can see the parameter has currently value of Send nothing. Therefore we need to program to firstly read the parameter in code, and then change it accordingly if necessary.

13 Import the library for IOL CECC-LK Use FB readparameter to get the value Program to write parameter by coding When the data carrier does not have the right parameter to send its UID, then we should use the FB WriteParameter to set the parameter with Index Coding and write operation ok Application Note CECC-LK as IO-Link Master connected to Balluff RFID Device and data carriers 1.10 Seite 13 von 17

14 Check the parameter again, and we see the value of this parameter has already changed to required one. Seite 14 von 17 Application Note CECC-LK as IO-Link Master connected to Balluff RFID Device and data carriers 1.10

15 2.3.3 Read stored data from data carrier Let s try to read first 16 bytes. Note: As per experiment, you can still send data by sending the command 01 in address 01hex no matter in which Activity at the Tag Present! Be careful that both AV in first byte and last byte must be activated! By this device, parameters of in process data are redundant, so you have to set both, otherwise it will cause error. Here the meaning of parameters is: read the 16 bytes of the data carrier starting from the address 0 (internal address of data carrier!). If everything is correct you will get activated AA and AE, and the first 16 bytes from the data carrier in Process Data address addressed from 01hex to 16hex..

16 As we can see in the software Now, all the data from data carrier are: You have the possibility to read data in code. After the read of data is finished, AV should be set to 0(release the new job pending) Seite 16 von 17 Application Note CECC-LK as IO-Link Master connected to Balluff RFID Device and data carriers 1.10

17 If everything is correct, you get AA & AE from Process Data Input deactivated. So the whole process of reading data is finished. And the process of writing data is quite similar, so I do not write the process in this note.
