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).
The following sensor types are possible for all temperature sensors.
• Pt1k: Platin 1000 Ohm
• Ni1k: Nickel 1000 Ohm
• NTC10K: NTC 10 kOhm
• Ni1kLG: Nickel 1000 Ohm LG (SBT)
