I am currently working on a project where the field signal is wired using Dupline to the HMI (VIPA Touch Panel).
Here is the issue.
The scope of the project is to have a field device wired via dupline to a profibus gateway (which acts as a slave). From the profibus gateway it gets converted to profibus and is read by two masters.
Master 1 is the DCS.
Master 2 is the VIPA HMI PANEL.
The VIPA HMI Panel has an inbuilt configuration menu that leaves me with two options. 1) MPI 2) Slave.
What does MPI mean? Does it really help me setup the VIPA hmi panel as a MAASTER?
