- Overview of the DDC3000-System
Building Automation System DDC3000
The DDC3000 building automation system is an operation and control system for the measurement, control, operation, optimization and monitoring of technical plants (BTA). It is developed on the basis of a 32 bit processor and works according to the principle of spatially distributed intelligence.
Components, Modules (Hardware)
The DDC3000 automation system consists of automation stations (DDC3000 central units) input, output and control modules on the switching cabinet bus SBM (Switching Cabinet Bus Module), input and output modules on the field bus FBM (Field Bus Module), room controllers on the field bus FBR (Field Bus Controllers) and modules for local priority control FSM (Front Switching Module).
Bus Systems
The DDC3000 automation stations communicate over a central bus, to which up to 99 DDC3000 automation stations can be installed. Communication with the field level takes place via:
- Switching cabinet bus for the connection of 16 SBM modules (input and output modules, control modules, gateway modules).
- Field bus for the connection of 63 FMB modules (input/output modules) and/or FBR controllers and/or room control modules. The connection can take place in combination.
- Kx-bus for the connection of 16 DDC circuit cassettes.
Programs (software)
The basic functions of the DDC3000 automation system consist of:
- Basic programs in the form of control functions for heater ventilation and set point controls, including control logic.
- Message management with storage of fault messages for messages from the technical plants (BTA) and system messages.
- Software menus, such as cascade, optimization, amount of heat computation, time programs, limit values etc., supplement the basic functions.
Operation
Operation takes place at the automation station with keyboard and LCD display in the dialogue with plain texts. The operation of the entire DDC3000 automation system is possible from each attached automation station DDC3000 (remote control) without additional equipment.
The SBM control modules have parameterizable switches/buttons and LEDS. The circuit cassettes have mode selectors and LEDs.
Interfaces
Direct connection to the BMS control center is via an RS232 interface. For remote BMS control centers, long-distance data transmission takes place via modem on the telephone network.
The integration and/or binding of other automation systems takes place at the automation level by means of the DDC3500 automation stations on the central bus and at the field level by gateway modules SBM50, SBM51, SBM52 on the switching cabinet bus.
