Currently, the OPC UA Server does not support publishing raw values directly from the PLC. It only publishes adjusted (scaled) values. This limitation severely limits OPC UA Server use cases.

Many variables are provided by the PLC in raw format and require scaling to obtain their true value. For example, a temperature value stored as an INT with a value of 775 needs to be scaled to 77.5°C. However, when this value is published via the OPC UA Gateway, it is rounded and published as 77, leading to a loss of precision.

This becomes especially problematic for setpoint values, as the limited precision prevents accurate adjustments from external systems. In such cases, precise control is not possible due to this rounding issue.
