D Subject to change
The user's guide 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 user's guide. We are not liable for any costs ensuing
for this reason.
1.2 Range of Application
The SIPART DR22 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
technical processes which the user can implement without programming knowledge and
additional tools.
In addition a robust adaptation procedure is available in this device which makes it much easier
to commission even critical controlled systems. The controller determines the optimized control
parameters independently on request without the user being expected to have any prior
knowledge of how the control loop may respond. The applied procedure is suitable for systems
with compensation and aperiodic transient behavior; even greater dead times are taken into
account.
For more complicated applications the fixed connection of the individual functions can be
canceled in the input range and replaced by a free structuring. The user can easily add extra
analog function blocks and connect them to each other and to the interfaces of the input range
with the software. This achieves optimum adaptation even to complex problems.
The named programming possibilities guarantee a great flexibility in the use of the controller
and allow fast, easy adapting of the device to the problem so that the SIPART DR22 can be
used universally for control jobs in processing engineering, e.g. as
-- fixed setpoint controller for one, two or three-component control, optionally with two
setpoints
-- DDC fixed setpoint controller for one-, two- or three-component control
-- follow-up controller (synchronized controller, SPC controller) with internal/external switching
-- fixed or commanded ratio controller with Internal/External switching
-- cascade controller (double controller)
-- ratio-cascade controller (double controller)
-- override controller with Min or Max selection of the manipulated variable (double controller)
-- double controller with two independent control channels
The extensive hardware equipment of the instrument by which numerous interfaces are
available for connecting the field cables is of advantage for the universal utilization. The
instrument can also be connected to master systems via a plug-in serial interface or operated
and monitored centrally by a Personal Computer.
The SIPART DR22 can be used alternatively as a continuous controller with a current output
signal or as a three-position step controller for controlling electric motor drives without changing
the hardware equipment.
