Hello all, I am trying to use a “DataSensing” S3N-W03 IOLink sensor with a X20DS438A B&R IOLink module. I have already an other “brand” of iolink sensor (Leuze) without any difficulties but with this I have an error when I try to connect from automation studion. In as, in the pysical view when I…

Thank for your help At the end we discover a “bug” in the sensor firmware. The B&R IOLink module start the communication immedately after the power supply is activ and that create a problem on the sensor. I’m waiting an update of the sensor but I activate the IOLink comm by the PLC code that work…

Thanks for your help. Now the communication seems working. With AS I can connect the sensor and read/write from the configuration page of the sensor. The sensor provide a digital output in addition to the IOLink and the problem occurs when I connect this output to an input of the PLC. For now I h…

I’m glad you were able to get it communicating! Unfortunately, I haven’t seen that specific error before. I’d recommend checking the Logger to see if there are any additional error messages there. The ioLinkWrite function block also has an errorCode output in addition to the Status output. Are you …

Hi Marcus, Thanks for your help. Have you an example of code to write a value in a specific index? My code works with a Leuze sensor but not with a sensor from DataSensing. In my code, after set to TRUE the enable input of the ioLinkWrite fb, I wait one PLC cycle, then I check if the status (out…

Hi Christian, Happy to help, and sorry I didn’t see this reply until now! I unfortunately do not have an example for using ioLinkWrite, but your process sounds correct to me as that is how most B&R function blocks are designed to work. It’s interesting that the sensor is seeing the same value writ…
