Explanation
DO1...DO6
Terminal on basis controller.
DO11...DO14 Terminal on extension module 1.
DO21...DO24 Terminal on extension module 2.
Comm
This output is connected via communication and therefore does
not occupy a hardware input. Some output signals can also be
connected via communication (see lists in the documentation on
the basics for LON, ModBus, BacNet).
Outputs may generally be enabled in parallel as well (via hardware
and communication).
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).
