Application Requirement

To control the Filling of material such as chilly powder, Wheel Powder of Auger Filling machine.System consist of 64 DI/DO with HMI and Axis positioning module and Programmable co -processor module. Control system was designed to control the weight of filling material where the weight is sensed by Weighing Scale.Two axis controls is done by Axis positioning. With the help of OIU, parameters such as quantity of the filling material can be set.

Customer Expectations

PLC system with accurate control of Quantity of powder.

VSAS Solution

VSAS has design the system with programmable coprocessor module and axis positioning module.With the help of OIU and as per the type of powder, the recipe is selected and the parameters are set accordingly.The weight of material is sensed by Weighing scale and the feedback was given to PCM module.VSAS Solution was based on

CPU System

90-30 Family PLC – with PCM module

I/O System

Consist of Series 90-30 I/O, 64 DI/Do

Axis positioning module

Here the positions for filling the powder were decided by this special card

OIU

Operator interface unit with various recipes was used to select the parameters such as weight, Specific gravity

Benefits

With the help of axis positioning module accurate position of filler were control, Accurate measurement of weight, No wastage.

Application Requirement

110 TPD Oil Plant Automation

System consists of 90- 30 PLC having Ethernet interface with Cimplicity Scada package,Control system was designed to perform,Control of Soft Column Operation of DEO (Deodorization),Control of Dosing Process, Control of De-waxing Process, Data Logging & Report generation.

Customer Expectations

Increase communication speed with ETHERNET connectivity, Improvement of the oil quality by improving process accuracy, minimum down time of plant, maximum production, Ease for maintenance, moderated cost.

VSAS Solution

VSAS has design the system with 90-30 PLC with Ethernet CPU and Cimplicity SCADA Package. Report Generation is executed in SCADA package.

Benefits

• Due to the SCADA as supervisory controller the system becomes user friendly & Parameter tuning possi ble at one place only
• Trending for SP, PV, CV as well as shifts wise report generation for all PID, various Alarm generations
• Fast communication between PLC & PC due to ETHERNET connectivity
• Critical process parameter calculated ON line to get better accuracy
• Reduced commissioning time

Application Requirement

Continuous vacuum pan automation,System consist of Versamax Modular PLC with Cimplicity SCADA package,Control system was designed to perform, Control of All PAN compartment, Control Of condenser water control system, Data Logging & Report generation

Customer Expectations

Improvement of process accuracy, minimum down time of plant, maximum production, Ease for maintenance, Report generation, Moderated cost.

VSAS Solution

VSAS has design the system with Versamax modular PLC and Cimplicity SCADA Package.Report Generation is executed in SCADA package.

Benefits

Previous system was with independent PID controller, Now all PID controlled by PLC so it minimizes the cost. Due to the SCADA as supervisory controller the system becomes user friendly & Parameter tuning possible at one place only.In this system all valves related to operation were controlled by PLC, all PID related parameters, can be set through Cimplicity. Trending for SP, PV, CV as well as shifts wise report generation for all PID, various Alarm generation. Less steam consumption so payback period is less. Improved crystal (Moscute) Quality
