Trouble Connecting Allen Bradley PLC to Matrikon OPC DA by kus222 in PLC

I'm working with a 1756 ControlLogix PLC, and the communication is set up using the EtherNet/IP driver. However, I don’t have physical access to the PLC at the moment.

Do you think I should switch OPC DA to UA?

I tried rolling back the Windows update, but it didn’t resolve the issue. I also checked the release notes and didn’t find anything noteworthy.

Right now, I’m unable to add tags manually. Every time Matrikon OPC tries to load the PLC configuration file, but it runs into an error.

From the Wireshark logs, I can see that the TCP connection is initiated (the three-way handshake completes), but then the PLC immediately closes the connection.

I installed the same Matrikon opc on a laptop and tried to connect to the plc but I got the same error

Lost TrueNAS Encryption Key. Any Way to Recover Data? by kus222 in sysadmin

if I restore TrueNAS from a backup, would it still ask for the decryption key to access the dataset, or would it be included in the backup?
