Hi all,
I’m trying to read my EH PMC21 Pressure Sensor data through an IO-Link communication. I have uploaded the IODD file EH provided to my software. It seems that I cannot assign PLC variables to the data item (Measurement Pressure Value) automatically or manually. However, I did that easily for other data items (Condensed Status and Switching Signals) [For more information, see the pictures below]. I’m wondering if anyone has any idea what could be wrong and if there are any possible solutions, that would be appreciated.
LREAL is a 64 bit datatype. I would try REAL. </p>[https://forum.plcnext-community.net/uploads/KY378E5QCDWU/image.png</a></p>
I tried replacing „Float32T“ as a Datatype in the document with „REAL“ and „REALT“ in the .xml file if IODD. It didn’t work out because these datatypes are not defined in an XML file, which makes sense. I ran to this error: Screenshot 2025-02-03 160018.pngDo you have any idea what I should change „Float32T“ to?

Hello,
How did you try to add a variable to the iol-1 / 1 / PD Input_MDC - Measurement Pressure Value?
In this case, you need to create your own real variable first before you can assign it to the process data. Can you try this? Please let us know if this doesn’t work. The option Right mouse button → add variabele does not work in this case:
I would not change the IODD as this is created by the manufacturer. Try to create a global variable with the REAL datatype and connect it to the process date.
The option Right mouse button → add variabele does not work in this case:
