Mapping Codesys with Sensor through Ethernet I/P

Hi Barron,

yes. I have made mistakes. The sensor need 4 Bytes to read 1 value.

I have asked new question regarding how to read these 4 bytes code. Still troubleshooting on how to read it.

Code for reading 4 address to get 1 value of sensor

Hi Umair, u can use an UNION DUT for this. You have to add an DUT [image] Fill it with your data structures, it is important to know tha every Variable in this union shares the same datastorage. for example you can write your REAL value, by accessing the array of bytes. [image] Instanciate the union in you POU (PLC_PRG, … ) and write your values. Sometimes you have to change the write order of the array, to change Byteorder of the REAL value. [image]

Thanks for your concern!

Best regards,
Umair
