AXL F IOL8 2H not reading transmitter

I have noticed that in Engineer 2021.6 with an AXC F2152 the AXL F IOL8 2H is not reading the connected sensor. I have an IFM TD2237 temperature transmitter connected to the IOLink master. I did import the IODD file for the TD2237 and connected it to the submodule 1. After that I have generated a global variable for the temperature value and connected that in the data list of the IOLink master for the: 1/process_data_inputs_temperatur. I have no indication that the IOLink port is active (Port LED is OFF) and no data is read from the IOLink port. When I go back to Engineer 2021.03.1 and downgrade the firmware to 2021.05 I have again the IOLink data. Peter Paul

Hi Peter, I’ve informed our IOLink specialists about your requests and one of us will come back to this soon. Frank

Hi Peter, my colleges retested the IOL feature with FW 2021.0.5, 2021.6 and PLCnext Eng 2021.6 using the templates 2021.0 and 2021.6 without seeing the error with our IOL devices. This seems to be an issue in combination with the specific IFM sensor. Can you give us maybe the specific order number and FW version of the device? BR, Frank
