DDC3000 Central Control Units

All DDC3000 Central Control Units consist of a 19" short cassette made of non-flammable plastic. They are designed as four-fold cassettes and have two plug-in sockets in the rear. Both plug-in sockets provide the operating voltage and the energy supply for the coupling to the DDC Central Control Unit bus, the DDC cassette bus, the DDC room bus, the DDC field bus and the DDC control cabinet bus.

The front panel contains the operator and display elements and a diagnostic jack. Behind a removable front panel are two rotary select switches for setting the address of the DDC3000 Central Control Unit.

The DDC3000 Central Control Units are supplied with an operating voltage of 24V AC, 50..60Hz.

The DDC3000 Central Control Units are bus-capable multi-circuit open- and closed-loop control systems for control, optimization, control and monitoring functions. The DDC Central Control Unit bus is based on the Profibus according to DIN 19245 and allows for the connection of max. 99 DDC3000 Central Control Units.

The central processing unit consists of a 32 bit processor and a real-time multitasking operating system.

These functional units are completed with a battery-buffered RAM, an open-ended data backup in case of mains breakdown and a clock module.

The actual time with date and hour can be called up. The summer / winter time switching is done automatically. The user communicates with the DDC3000 Central Control Unit via the operator keyboard and a 4x20- character illuminated LCD display.

The dialog is carried out in plaintext in three possible operator levels for queries, and input for the DDC data, such as actual value, setpoints and times. A plaintext can be installed for all DDC parameters.

All DDC open- and closed-loop control parameters are entered in the program level,. A virtual parameterization is possible.

The three operator levels and the program level are divided into four priority levels per code key.

The open- and closed-loop control software acts differently depending on the type installed in the DDC3000 Central Control Unit, the DDC control loop cassettes, and the DDC single-room regulators. The DDC control loop cassettes and the DDC single-room regulator continue to work autonomously even when the DDC3000 Central Control Unit has failed. The manual activation level is a constituent part of the basic program of the DDC control loop cassette. Switching processes are entered and carried out via digital inputs and outputs in the DDC3000 Central Control Unit. Every possible digital output and input can be used for issuing a collected error message and for its receipt. For all digital inputs and outputs, a separate power supply is provided to supply the 24V DC.

Analog inputs and outputs are processed according to type. Via a parameterizable sensor switching mechanism, the analog inputs can be made to accommodate the input signal.

The serial interface allows for RS-232 communication on the basis of the P90 protocol. The following functions are realized via the serial interface:

- BMS operator station, BMS central control station with direct line connection or modem

– send via the SMS (Short Message Service) malfunction notifications in plaintext to a cellular phone - data backup / data recovery with portable PC / BMS central control station (data backup)

The DDC3000 Central Control Units are connected on a common DDC Central Control Unit bus. This makes possible

– the access of the parameters of other DDC3000 Central Control Units – the transfer of error messages to other DDC3000 Central Control Units

Data backup / recovery via PC with DOS-operating system

The serial interface RS-232 of the DDC3000 Central Control Unit is used for data backup with the KD-PC (operating system MS-DOS).

For data backup, this interface is available as a diagnostic jack and is installed on the front panel of the DDC3000 Central Control Unit.

Connection of DDC3000 Central Control Unit with KD-PC for data backup

· Diagnostic jack of the DDC3000 Central Control Unit and serial interface of the KD-PC connected with the data

line DDC3000.001.

Caution: The serial interface RS-232 on the plug-in socket may not be simultaneously assigned! (for example, with a connection to the stationary BMS)

· Select via the menu system of the KD-PC the menu position [DDC3000] ([EZR]).

· In the menu of the started data backup program, select the desired menu position.

data backup (3000 to the PC) = 1

data recovery (PC to the 3000) = 2

· After the query and the input of an arbitrary name for the backup file, the parameter settings are shown on the

PC, which must be set on the DDC3000 Central Control Unit in the software menu 69 system menu.

Set parameters in the system menu of the DDC3000 as follows:

No. 4599 P90-protocol = ON

No. 4600 P90-baud rate = 9600

No. 2051 P90-Mode = DATA BACKUP and finally

confirm the P90-Mode on of the DDC3000 with <SET>. Now the data will be backed up.

· Make the required parameter settings on the DDC3000 Central Control Unit in the DDC software menu M069

system menu.

When the last parameter is set and the key [SET] is pressed on the DDC3000 Central Control Unit, the data backup runs by itself and terminates automatically.

The data backup runs as a background program of the DDC3000 Central Control Unit. That is, other operator commands on the DDC3000 Central Control Unit can be carried out, but do slow down the process of data backup.

Update with FLASH card

The DDC3000 Central Control Unit DDC3002, DDC3200 and DDC3300 have a PCMCIA plug-in socket on the front side (under the front panel), on the left next to the LCD display. A FLASH card can be plugged in here. With the

FLASH cards, the parameterization can be backed up, restored or new DDC3000 programs can be loaded

(update).

As of the version 2.54, updating the DDC3000 Central Control Unit via the parameters setting of the DDC software menu M69 is possible.

When updating the DDC3000 Central Control Unit, i.e. when loading a new program version, the following processes occur:

1. The parameterization of the DDC3000 Central Control Unit on the FLASH card is backed up automatically.

2. The new DDDC3000 program in the DDC3000 Central Control Unit is loaded automatically.

3. The parameterization of the FLASH card in the DDC3000 Central Control Unit is restored automatically.

4. The DDC3000 Central Control Unit is automatically started new with a warm start.

Automatic processes when updating the DDC3000 Central Control Unit with FLASH card
