Advanced operator controls and interfaces
The figures below show the terminal designations (slot numbers) for the Advanced
installation components and their wiring.
Front
Example of Extension Unit 22", minimum configuration: 1 × KP12 and 8 additional slots. In
the figure, 3 RGB illuminated pushbuttons are installed and the other operator controls are
marked with dashed lines. An RFID reader can be installed on the left and right in each case
(dashed rectangles, see section "Extension Unit Advanced (Page 12)").
When the KP12 and the 8 RGB illuminated pushbuttons (dashed circles) are cabled one
after the other from left to right, their slot numbers are also sequentially numbered from 14
(left) to 22 (right).
Note
Connection sequence, slot number 14
The order in which the connection cables are inserted (connection sequence, see rear panel)
determines the slot number. The first Advanced installation component connected to the
internal bus always has slot number 14, because the first 13 numbers are reserved for the
Standard installation components and the communication module.
•
The second Advanced installation component connected to slot number 14 has slot
number 15, regardless of its mounting position.
In contrast, the terminal designations for an Extension Unit Standard depend on the
mounting position:
•
The Standard installation component at the second mounting position always has the
number "2".
Standard operator controls can be installed in the Extension Unit Advanced in parallel, if the
corresponding mounting positions are free.
