Note: Performing a multiplex module data exchange requires a
number of poll cycles from the DP Master to the PanelView
terminal. During each of those poll cycles real time data is
constantly being exchanged.
The diagram below shows the relative position of the Real Time and
Multiplex modules in the data packet sent between the DP Master
and the PanelView terminal. The modules reside in the DP Master’s
database in the same relative position.
