System role

This section explains what the product does and where it acts in the surrounding system.

Function: Displays graphics on a 3-inch backlit LC operator panel and communicates through MPI/PROFIBUS-DP for a SIMATIC HMI installation.
System position: Sits between the operator or machine process and the host automation system as the simatic op 73 operator panel interface.
Upstream / inputs: Operator actions and the connected controller or industrial-computer signals provide the upstream system inputs.
Downstream / outputs: The operator receives the documented visual or control interface, while the host automation system receives the corresponding operator interaction.
Limitations: Unknown: installation-specific compatibility, firmware or project configuration, replacement suitability, and current commercial availability were not established by this individual research.
