Internal devices are device registers available on the display unit.
The internal devices include an area you can use dependent on the communication method of connected devices, as well as an area known as the USR area that you can use freely, regardless of the communication format (USR Area).
This section mainly explains the different areas you can use, depending on the communication method.
For more details on the communication method and the USR Area, refer to:
