Hello I am trying to read a tag from a 1200 series siemen PLC.

Here is my Tag Configuration inside ignition,

The PLC is configured correctly and connected under device connections in the gateway.

PLC: 6ES7 215-1AG40-0XB0
Firmware: V4.2

Why is the ignition value this large seemingly unrelated number compared to the monitored value in TIA. Is my OPC Item path syntax incorrect? Thank you!

Yes, you need to use the sytnax indicating the datatype is Real (REAL) instead of DWord (D).

Try [Control_TL_1]DB8,REAL22 instead.
