1 Technical Description

1.2 Range of Application

D Subject to change
The manual has been compiled with great care. However, it may be necessary within the
scope of product care to make changes to the product and its operation without prior notice
which are not contained in this manual. We are not liable for any costs ensuing for this rea-
son.
1.2 Range of Application
The SIPART DR24 is a digitally operating device in the top class range. Its program memory
contains a large number of prepared function blocks for calculating, controlling, regulating in
chemical engineering processes which the user can implement without programming knowledge
and additional tools. Mathematical functions, logical functions, comparison and switching func-
tions, timing functions, memory functions, control functions and a program generator are stored.
All function blocks are freely connectable with each other and with different inputs and outputs
of the controller by the software.
The controller can therefore be used to solve a wide range of different problems. A large num-
ber of display elements (digital, analog displays, LEDs) and control elements allow display and
control of the processes on the front panel.
This controller contains a rugged adaptation procedure for the stored controller components
which noticeably simplifies commissioning of even critical control loops. The controller deter-
mines the optimized control parameters independently on request without the user being ex-
pected to have any prior knowledge of how the control loop may respond.
The SIPART DR24 can operate with up to 4 independent control loops. Tasks in which it is nec-
essary to use interconnected control equipment (e.g. cascaded control, cascaded ratio controls
or override controls) can therefore be performed with one controller.
The extensive hardware equipment of the controller allows its universal application and provides
a large number of interfaces to the control loop.
The controller can be connected to master systems through a pluggable serial interface
(RS 232/RS 485 or PROFIBUS DP) or operated and monitored centrally by a Personal
Computer.

Design (Hardware) Software

The SIPART DR24 has a modular design and is therefore service friendly and easy to convert
and retrofit. Other signal converters can be installed in the generously equipped, fully functional
standard controller to expand the range of application. These modules are installed in slots at
the back of the closed device (Figure 1--2, page 10).
The standard controller consists of
-- the front module with the control and display elements
-- the main board with CPU and terminal strips
-- the plastic housing with an interface board
-- the power supply unit.
