SIMOTION TControl technology package
TControl – Temperature controller technology functions
Temperature channel technology object
The controller core of the temperature technology package has
a DPID structure. Pure heating controllers and cooling
controllers as well as combined heating/cooling controllers can
be configured and parameterized.
User-assignable functions are available for each temperature
channel:
•
Each temperature channel can either be configured as a
heating or cooling section or as a combined heating/cooling
section.
•
The controllers either use a PID or DPID control algorithm or
use the optional control zone functionality.
•
In manual output mode, a replacement value can be output.
•
You can select the operating mode for each controller channel
separately. In this way, for example, you can switch the output
to a fixed control variable.
The following operating modes are available:
- Closed-loop control for operating setpoint
- Actual value acquisition and output of the manual
manipulated variable value
- Actual value acquisition and output of "0"
- Self tuning
•
Actual value acquisition and processing
- Plausibility check for each new actual value and correction
before corresponding filter measures
- Filtering (by PT1 element)
•
Actuating signal preparation and output
- Digital, pulse-length modulated actuating signal
- Prevention of minimal pulse durations for I/O cycles by
integration of lost pulses
- Manual actuating value (for manual output mode)
- Output value limitation
- Replacement value (calculated dynamically)
•
Self-tuning for heating controllers
-
This ensures fast startup without overshooting and maintains
the setpoint value without lasting system deviations.
-
Self-tuning can be used in parallel for all desired channels to
ensure optimal parameter acquisition even for strongly
coupled temperature sections.
•
Monitoring and alarm functions
-
Actual value monitoring by definition of tolerance bands. The
inner and outer tolerance bands can be defined
independently as absolute or relative tolerance bands.
-
Measuring circuit monitoring for increased operational safety
of a plant
- Plausibility check
- Alarm functions
The use of the TControl technology package is clarified by an
application example. The application example provides
functional expansions, function interfaces to the application and
data interfaces to the HMI. It is contained in the Utilities &
Applications which are supplied with SIMOTION SCOUT.

Drive Control Chart (DCC)
Technology functions for Drive Control Chart
With Drive Control Chart (DCC), open-loop and closed-loop
control functions can be easily configured graphically. For this
purpose, multi-instance function blocks are selected from a
block library using drag and drop, and then graphically
interconnected and parameterized. The control structures are
presented clearly.
DCC is not available for SIMOTION in the TIA Portal
(SCOUT TIA).
The block library comprises a large selection of
•
control blocks,
•
calculation blocks, and
•
logic blocks as well as
•
comprehensive open-loop and closed-loop control functions.
Further functions:
•
For logically combining, evaluating and acquiring binary
signals, all commonly used logic functions are available for
selection including, for example,
- AND
- XOR
- On/Off delays
- RS flip-flops or counters
•
For monitoring and evaluating numerical values, numerous
arithmetic functions are available, such as:
- Summation
- Divider
- Minimum/maximum evaluation
•
Apart from the automatic speed control, winders, PI controls,
ramp-function generators and wobble generators can easily
be configured.
More information about Drive Control Chart (DCC) can be found
in section Option packages for SIMOTION SCOUT.
