CAT NO: DIDACTICNLE-Export-210011
Trainer For Field Bus Applications- Engineering Lab Training Systems.
Technical Description
Field bus technology plays a key role
in modern-day process automation. The field bus permits networking of
terminal devices such as controllers, sensors or actuators in the plant
system (field level) with the higher-level control room (control level).
A network of this kind can be quite extensive; line lengths of as much
as 1000 metres and more are possible.
This benchtop
trainer is used to teach the initial basic steps in field bus technology
based on the example of Profibus DP. Various terminal devices (slaves)
are activated and read by a PC with a Profibus DP interface (master).
The required hardware is largely pre-configured. Students are able to
concentrate on the software programming of the field bus system. The
following specific topics can be covered: System configurator with DMF
(Device Master File), bus topology, communication protocols, tags, OPC
(OLE forProcess Control) server, input and output of process data, and
much more.
The unit includes a digital process controller as well as analogue and
digital input and output modules with a Profibus DP interface.
Two
potentiometers permit the simulation of input signals for the
controllers. A digital voltmeter displays the output signals. Digital
signals are generated by switches and displayed by LEDs.
The
controlled variable, manipulating variable and reference variable data
are delivered as standard signals at lab jacks, enabling the controllers
to be incorporated into real processes at any time.
Clearly structured instructional material outlines the fundamentals and
provides a step-by-step guide through the exercises.
