Siemens Standard application AHU CE1P3977en_02
Building Technologies Configuration 01.02.2010
Position Explanation
X1...X8 Terminal on basis controller.
X11...X18 Terminal on extension module 1.
X21...X28 Terminal on extension module 2.
Comm Sensor is connected via communication and therefore does not oc-
cupy a hardware input. Some sensors can also be connected via
communication (see lists in the documentation on the basics for
LON, ModBus, BacNet).
Sensors may also be enabled in parallel as well (via hardware and
communication).
The value selector must be set accordingly when enabling via com-
munication (for details page on Analog Inputs, Sec.
6.5.2.).
NUsd No used: The hardware position is not yet selected. The plant is
locked against switching on if an enabled sensor is set to NUsd and
the following fault issued: NotConfigured (Function enabled, but
hardware not assigned).
15.3.4 Humidity
The listed hard assignments are possible for all humidity sensors.
