Simeq System
The SIMEQ System is a computer control solution based on Matlab
from The MathWorks with additional toolboxes depending on application.
Matlab has for many years been recognized as state of the art in control engineering
and a full scale SIMEQ system will include some or all of the following:
For a full list of all available toolboxes see: http://www.mathworks.com/products/product_listing/index.html
The system enables use of the capabilities in Matlab in a real-time environment, where applications
are executed at specified time intervals. The incorporation of Matlab makes the system a “state of the art”
in process analyses and control.
All features from Matlab can be used in the plant control and optimisation.
The SIMEQ system sets up a number of applications, each having their own workspace. These applications
can all be accessed from the Windows Start Menu, as seen below:
 One application will typically hold one
plant department, but if several
department controls have remained
unchanged for a long period, there is
nothing prohibiting e.g. control of three
cement mills as one application.
The programs, parameters and variables
of each application are organised in a
hierarchical way, so no interference
between the departments arises, if you
follow the SIMEQ set of guidelines for
Matlab programming.
Several independent instances of Matlab
are in operation at the same time, enabling
time-consuming tasks to be executed in a
server, not busy with the tasks having to be
performed at short precise intervals.
All tasks can communicate with each other and data can be exchanged.
Programs are written in the normal Matlab language and the SIMEQ system can be considered as a set of
functionality, added to Matlab. Programs can be shared between many applications or belong to one application.
All programs can be edited on-line. After editing, the new version op a program substitutes the old in the first scan
after you have pressed save.
SIMEQ makes signals in the control system available in each application and easy reference can be made to all
signals. Writing back new control setpoints to the control system is likewise done with simple commands.
The logging system of the control system can be used for incorporating historic values in the process control or
reporting.
An ‘easy to use’ interface to Excel is part of the SIMEQ system, so reports can be made as Excel spreadsheets.
The spreadsheets can be automatically sent to any recipient by email. Excel can remain invisible during report
generation.
At the present interfaces exists to any OPC compliant server and the ECS system from FLS Automation.
The OPC interface can, via a standard OPC server, be connected to practically all PLC systems.
