3.8.2 Process image
The CP9xx alarm indicator and operator panel combines the information from the different interfac-
es and makes it available for operation and visualisation via the web user interface of a PC.
It acts as a central user interface. In order to be able to identify them, one individual address is avail-
able for each device on this interface. BMS, BCOM and Modbus RTU devices receive the appropriate
address for their interface. A virtual address is assigned to Modbus TCP devices.
3.8.3 Control of operating theatre lights
Operating theatre lights from different manufacturers can be controlled via the CP9xx. Most operat-
ing theatre lights feature a USB or RS-232 interface. The CP9xx can be connected via this interface.
RS-232 interfaces require a converter from RS-232 to USB. The control (and the communication pro-
tocol) was tested and verified together with the operating theatre light manufacturers.
The functionality and design of the CP9xx controls are adapted to that of the operating theatre
lights. The operating theatre light functions can be parameterised for specific projects in the CP9xx
interface. In general, only the functions provided by the communication boxes of the respective
manufacturers can be used.
The installation instructions of the communication boxes can be found in the documentation pro-
vided by the manufacturer. The manufacturer is also responsible for service. An overview of the sup-
ported operating theatre lights can be found in the document D00349_N_DEEN.
