9.1
Communication module KOM232PC
The connector for the optional communication module (Mat-No. 11988) is located on
the left side (front panel view) inside the controller housing (RJ45 connector). The
operation of the controller in conjunction with the communication module KOM232PC
requires the use of appropriate communication tools (software).

9.2 Communication module iCon485
The connector for the optional communication module iCon485 (Mat-No. 11994) is
located on the left side (front panel view) inside the controller housing (RJ45 connector).
The operation of the controller in conjunction with the communication module iCon485
requires a permanent bus connection (data cable).
Each controller and control unit is wired to an open token ring. The end of the wire is
connected to the building control system via an RS-485/RS-232 converter (e.g.
CoRe01).
The bus connection range (cable length) is limited to a maximum of 1200 m. A maximum
of 126 devices can be connected to such a segment. In segments with a longer distance
(> 1200m) or in segments with more than 126 devices, repeater have to be installed to
maintain the signal strength (e.g. CoRe01). On a bus with 8-bit addressing, a maximum
of 246 devices can be connected and addressed.
In times where the communication between the building control system and controller is
interrupted, interventions of the building control system into dynamic processes can be
influenced with the function
building control system monitoring for a limited period of
time.
