Hello everyone,

I’m struggling to read and write with a Beckhoff TC3 control unit and a Siemens RFID reader. I downloaded example project from here: SIMATIC Ident an Beckhoff Steuerungen anbinden via PROFINET und EtherNet/IP - ID: 109807653 - Industry Support Siemens and have established a PROFINET connection and can successfully send the WRITE_CONFIG command (CMD 0x78); the RF340R changes from blue to green, so everything appears to be OK. The READER‑STATUS command (CMD 0x74) also works (the bDone flag is TRUE).

However, when I place a tag on the RF340R and try to read the status of tag (D423) using command 0x73, I receive no feedback. The device remains in the bBusy state (TRUE) and does not clear. The same thing when I try to read the tag wit CMD 0x70...

Could anyone advise what I might be doing wrong?

Thank you.

RF186C: 6GT2 002-0JE20 FW Version: V02.02.00.00_02.21.05

RF340R: MLFB: 6GT28012BA10 FW: V 2.0 (V2.0.10)

MDS D423: 6T2600-4AA00

Looks like you're almost there.

Does the color of the reader's LED change to yellow, when the tag is placed on the reader? If not, you only need to change the tag type in the last byte of the data of the Write Config command.

In your video at 2:34 you can see, that there's no tag (variable b Tp)

You can see details of the commands in the web interface (diagnostics\logbook)

Correct, the LED doesn’t change to yellow.

Can you please help me adapt the Write Config command so that the MDS D423C is recognized (RF340R changes from green to yellow)? 

If it's help, in attachment you can find config file of RF340R.

There's nothing you need (or can) do in the Web interface of the device. You need to modify the data of the first command.

Details on the data structure can be found in the manual, please see in this thread

Since you're using a RF200 tag too, it also has to be 1 in your case.

The Write Config command has 16 bytes of data. It's the last byte (of the 16) in aTxref.

Thanks! In the meantime I figured it out (finally).

I found this topic:https://sieportal.siemens.com/en-ww/support/forum/posts/rf340r-can't-detect-mds-d424-tag/128653.

So I tried: in Reset Datat[16] I changed: aDataReset[16]:=16#0; to aDataReset[16]:=16#1; (see gif attached).

Now the RF340R recognizes the tag (it changes from green to yellow), and all other commands are working!
