DCS Trainer

Procured under the Grant received under TEQIP Scheme of the World Bank



The Forbes Marshall DCS trainer is a completesystem that combines a DCS (Distributed ControlSystem) and PLC (Programmable Logic Controller)along with process rigs in one compact unit.

It is Manufactured By Forbes Marshall Pvt. Ltd.

Pune ,India.

It combines the ability to collect data andsimultaneously feed 4 test rigs and control. It has thecapacity to provide a comprehensive output.

The Process rig for Level & Flow is developed byFeedback Instruments Ltd. & Supplied by ForbesMarshall .

Features & Benefits

•All process parameters can be controlled

simultaneously.

•The DCS Trainer is extremely flexible, yetcomprehensive. One can connect all test

rigs to the Trainer for a comprehensivegraphics based control and testing.



Features & Benefits

Trainer for DCS or PLC

The system can combine the features of DCS & PLC in this trainer byrunning through the various experiments. The experiments have a theory to

go through prior to executing the practical. The industrial process mimicswill appraise the student to get the industrial feel.

It can simulate an industrial environment

Output from the DCS Trainer includes both, graphical representation of thetest rigs as well as actual industrial process graphics.Switch with ease between both to obtain an immense industrial experience.



Test rigs can be used either with the system or separately

Features & Benefits

•The DCS trainer is available separately for those who already own test rigs.Optionally test rigs are available with the Trainer to meet individual needs.

Start comprehensive training even with one rig•Even if all rigs are not available, the DCS Trainer's sophisticated software takes

over the task of simulating the actual field values for the balance inputs by feedingmanually.

Efficient data handling

• Data logging is efficient and advanced. Data from configured tags is logged everysecond and can be viewed for trends, or printed on reports. The alarm managementis handled effectively by the software.



Report generation - a wide variety.

Features & Benefits

The DCS Trainer comes with a variety of pre-configured reports built in.Choose from these Standard Reports or define your own parameters forcustom reporting. Both, Trend reports and Status reports are available, such

as shift reports, daily reports or experiment reports.

Range configurable as per users requirements

The input ranges can be configured on the software as per theneed of the user. Every channel of the analog inputs can be

connected to various types of signals from the field, such as 4-20mA or 0-20mA.

Flow and Level Process RigFlow and Level Process Rig

The level/flow process trainer is a single loop system allowing the study of Theprinciples of process control, using liquid level and flow rates as the Measuredprocess variables. The system is a completely self-contained, low pressureflowing water circuit supported on a bench top-mounted panel, making itsuitable for individual student work or for group demonstrations.

It comprises a dual compartment process lank, linked to a sump tank by manualand solenoid Operated valves. Water is pumped through the System, via a van

able area now meter and Motorised control valve. Level is measured in theprocess tank. Flow IS measured through an optical pulse flow meter.



Features:• Use water as the process medium.

• It is controlled using industry standard 4-20mA signals.

• Control of the system being affected by a linearized profiled seat, electrically-actuated gate valve.

• The rig has three tanks which are constructed of welded polycarbonate.

• The three tanks are: a sump tank and a 3L and 2L dual compartment Process Tank.

• The level and flow rig is fitted with a submersible 10 L/min 12V dc pump.• Level is measured using either a Float Switch or a Float Sensor. Flow is measured using a 0 to 4.5

L/min Pulse Flow Sensor.

• Flow can be observed using a 0.4 to 4.4 L/min Variable Area Flow meter.

• The system incorporates different orifice solenoid valves allowing step change of supply & drainrates.

• Contains selection of level and flow sensors & indicators

• Flow controlled by linear motorised control valve

• On/Off and proportional control

• P, PI and full PID control with auto tune facility

• Modern push fittings

Elipse SCADAElipse SCADAIt is a Supervisory, Control & Data Acquisition System based on Windows.

The Organizer gives you a clean and organized view of all the application, helping edition andconfiguration of all the objects involved in the system through a hierarchical options tree.

Elipse Windows has 4 brand-new tools:

•ELIPSE WATCHER:•SCADA software for system monitoring including digital image acquisition, storage and transmission in real time. Supports a varietyof file formats, including MPEG. Allows you to create an image database searching by period or event and also image transmission inreal time for remote stations using TCP/IP or dial-up connection.

•ELIPSE WEB:•Supervisory and control system through the Internet. Using a commercial browser (Internet Explorer, Netscape, etc.) you can connectto a remote supervisory station, receiving data in real time.

•ELIPSE POWER:•Allows connection with IED’s (Intelligent ElectronicDevice) and RTU’s (Remote Terminal Units) using anycommunication protocol, including IEC 870-5/DNP 3.0.Uses a local time base, allowing SOE (Sequence of Events)with 1ms precision and oscillography, wave formtransferring and visualization in local stations or talesupervisory systems.

•ELIPSE LAB:•System for laboratory test applications, allowing graphregisters and oscillograph substitution, ATE’s constructionand creation of virtual instruments. Has GPIBcommunication (including IEEE-488.2), RS-232/422/485and a driver development kit for any instrument.



Elipse Symbol Factory• It is Used to Draw the Mimic In Elipse SCADA.



CoDeSysCoDeSysWhat is CoDeSys?

• CoDeSys is a complete development environment for your PLC. (CoDeSys stands forControlled Development System).

• CoDeSys puts a simple approach to the powerful IEC language at the disposal of thePLC programmer. Use of the editors and debugging functions is based upon theproven development program environments of advanced programming languages(such as Visual C++).
