Figure 20. System Stacking Connections
Operation
All operation of the stacked system is done through the Primary controller either
with the front panel or remotely. This is no different than when used as a single
unit. Programs, Tasks, Diagnostics, and other features are available and can be
used in stacked mode. When connected, the system uses the settings of only the
Primary controller, which eliminates the need to configure each controller. When
connected, the Primary system detects the other systems connected and
automatically identifies them as Auxiliary 1 and Auxiliary 2 (see Figure 20). All
manual control of the Auxiliary units is disabled with the exception of the Abort
button. If at any time the Primary unit is turned off, the Auxiliary systems shows a
dialog box letting the user know that the connection to the Primary unit has been
lost.
