Hello, I've been following tutorials and using the LMQTT block for the Siemens s7-1200. After setting the block up, I get an error saying data type "TCON_QDN_SEC" no longer exists (see attachment). Considering it's a given library (link), I'm not sure why this error is showing up. The PLC is connected fine and can be recognized by TIA portal. Any suggestions that might solve this? Thank You.

Hi, You need a CPU with firmware 4.4 to support QDN_SEC (working with names instead of IP addresses and encrypted secure communication).
