Problems with RFID read/write

------------------------------------------------------------------------------------------
Split from Profinet and IO Link modules.

You can see the Input and Output address defined in each module of the RFID device. You need to check with the RFID device document what is stored inside the HF compact and just read the address.

For example HF Compact has address 124..135 as input address

You need to call the address Input address as %IW124 in your network and use it wherever required. Similarly for Output address you can simply call %QW125. 

The above is just example. Just make sure you call the correct address. Also if it is Digital input or output stored in that address, you call the specific bit as IW124.0... 124.7 which has eight bits stored in it.

Hi,
