Mettler Tolledo scale vs other scales from the communication point of view.

I am trying to increase my understanding of scales principles and please correct me if i am wrong.

My understanding is that mettler tolledo is a true level 1 device (similar to the PLC) in a way that its input value (weight) is being transmitted to the receiver without any additional components siting on top of its architecture similar to the PLC which would not be functional without any connection to the outside control object.

This is different to other manufacturers who produce scales which read the value but the transmission of the data is processed by an additional component or an built in application which provides additional functionality but is slower and less reliable.

Please share your feedback if my statements and understanding are accurate i am trying to improve my understanding in the area.
