Hi you,
the 24V factory is working with fixed IP addresses, 192.168.0.1 is used for PLC 192.168.0.5 is used for RasPi with node-red running
and 192.168.0.10 for the TXT.
First step is to check if all network participants are visible in your network.
I use the "angry ip scanner" software for that.
The RasPi is the network bridge between PLC (OPCUA) and TXT (MQTT) in the node-red app (http://192.168.0.5:1880/)
you can check the status of the OPC-UA server connection.
The behaviour that you describe is, when there is no (or to late) data transmitted from MQTT to PLC then the part is dropped into "bad part" box.
The MQTT messages from the RFID reader connected to the TXT are not send when:
a. there is no connection (IP address wrong, cable not plugged in , etc.)
b. the clocks of PLC, RasPi and TXT are not synchronized,
then the TXT is dropping messages with invalid timestamps.
So the data read from the RFID reader is not coming from TXT to PLC within the timeout period.

I documented my network infrastructure.
It should look the same in your case...
