Its a hardware, which is directly in contact with field instruments. Outputs can activate the field equipment Motor, Solenoid valve etc. These programs can be change or modified as per the requirement.

Software Solutions In terms of the PC-based software packages used to program these platforms and systems, both combined and separate units are merging the HMI and PLC programming features into a single integrated package or all-in-one configuration software. These suites of software integrate the PLC programming software, HMI development software, and system configuration software in a single development environment.

While well integrated, the PC-based programming software can still be two separate programs Hmi vs scada together with configuration software. The separate HMI can be one of two types. This software can be either internally developed, or it can be purchased and configured.

The second separate HMI type is an operator interface terminal, where the PC-based programming software is supplied with the terminal. The PC-based HMI solution sets the standard from an operator interface standpoint with its wide variety of features, functions, options, sizes and display resolutions.

Vendors provide a full range of analog, discrete, motion control and specialty modules to meet the needs of most any application. Figure Hmi vs scada, super sack filler, courtesy of TBMA.

A bag filling machine or station is used to fill industrial bags with various types of materials.

These bags are typically used to ship large amounts of product to other businesses, and are generally not suitable packaging for direct shipment to consumers or retail outlets.

The automatic cycle can free up the operator to tend to other plant operations.


Ultrasonic sealing can also be monitored and controlled. The HMI also allows fine tuning of the fill, densification and weighing processes to improve efficiency and performance.

If required, encoders can be monitored and stepper motors controlled for the accurate positioning often required for material handling systems. Complex Machine Requires Separate System Materials such as paper, plastic film, foil and cloth are usually produced in long, continuous sheets which are rolled to facilitate handling and transportation.

Web converters take these continuous rolls of thin, flat materials websthread them though processing machines, and convert or change the web to an intermediate form or final product. This web converting line Figure 3 unwinds a thin film solar material and converts it into individual solar cells, tests the cells for efficiency, and then sorts the cells based on performance as measured by the test.

The individual cells are then assembled into solar strings and packaged for commercial use. Figure 3, web converting line image. It includes multiple axes of motion control to provide roll unwind, tension control, and precision indexing for use with laser etch, dispense, shear, final test and sort processes.

This application also required Ethernet communication to an etching laser, two robots and three cameras. Upstream, this web converting line included a servo drive unwind system controlling tension in the web, and a second servo providing web edge alignment. The unwind servo followed the downstream cut-to-length system.

The line was required to hold a high precision tension, control the web edge position, and accurately index the web material—so high-end precision motion control was required. Just downstream of the unwind, the edge alignment servo positioned the edge of the web within the field of view of the laser and web find camera.

The laser adaptively etched the edge of the product as part of the process, and once etched, the web was indexed. The web position was then communicated to the PLC and forwarded to a dispense robot to provide vision-guided dispense of an adhesive material.

Precision indexing and a high speed sensor were used to provide accurate and repeatable cut-to-length capability at the shear. Once sheared, an outfeed conveyor servo indexed the sheared product to a vision inspection system. After the product was dimensionally inspected, the product position was sent to a robot which was triggered to pick up product and place it in a tester.

Following test, the product was robotically picked from the tester and placed in one of 12 sorted positions or in a reject bin, depending on the test results.

All of these operations were coordinated by the PLC, and all were monitored and controlled from the HMI which included machine status, set point adjustment and fault messages.

The separate system has the widest selection of configurations and processing power, setting it apart from most combined units.

plc, dcs, hmi, & scada Since , we have been implementing Programmable Logic Controllers (PLC), Distributed Control System (DCS), Human Machine Interfaces (HMI) and Supervisory Control and Data Acquisition (SCADA) systems.

SCADA vs HMI SCADA and HMI are control systems that are used in any organization.

DIFFERENCE BETWEEN PLC & SCADA - Entries - Forum - Industry Support - Siemens

While SCADA refers to supervisory control and data acquisition, HMI is simply human machine interface. Industrial and infrastructure processes are normally monitored by computers. SCADA has applications in manufacturing, production, power generation, . SCADA vs HMI In large industrial structures, it is impractical or even impossible to control the individual parts of the system because, in most installations, the parts are often located very far from each other.

Thus the need arises to monitor and control them with SCADA and HMI. The main difference between SCADA and. C# HMI vs. Commercial Off-The-Shelf Solution. SCADA systems, processes and the list goes on. Reliability. The reliability or robustness of any custom C# HMI application that you develop is an important one.


One of the overriding requirements for any production environment is reliability. Automation systems need to be designed such that.
