Using a Framework for a PLC Project | Sofcontraining.com

Why should I use a framework for my control and automation projects?

Before we start looking at the reasons for using a common framework, I’ll start by explaining what it is I mean by it.

Simply, a framework is a piece of software or a library that provides generic or common predefined functionality. The framework is reusable and can be extended by a user in order to provide a bespoke / custom solution.

Advantages

Efficiency and Cost

The framework will typically provide up to around 50% of the application developments features thus resulting in a huge saving in time. In addition, the use of predefined, pre-tested code will dramatically reduce development and coding time.

Improved documentation and customer support.

Once again, the use of the software framework and predefined code will speed up the production of manuals as much of the content relating to common automation tasks can be written once and used time and time again.

Quality

The use of predefined , pre-tested code dramatically improves the quality of the software product, ensuring consistency and fewer programming errors.

I’m going suggest two frameworks.

The first shall cover PLC and the second HMI.

PLC Framework

The framework should be split into program areas covering,

• Version
• Constants
• Global Code and Startup
• Input Mapping
• Safety Interface
• Interlocks
• Recipe Handling, Engineering SP
• Data mapped from the HMI or SCADA
• Data mapped to the HMI or SCADA
• Device Handlers
• Alarm Handling
• Output Mapping
• Communications setup
• Statistics
• Any program sequences.

The picture below demonstrates this. The example shown was created using Mitsubishi GXWorks 2.

Note: The program naming does not dictate program flow as this can be set elsewhere.

 

HMI Framework

The HMI framework should incorporate the following generic features:

• Security – Predefined levels of access
• Multi Language Support
• Alarm Handling
• Logging
• Trending
• Common Icons, Pushbuttons and displays

A post-Invensys-acquisition update

By Rick Zabel, Publisher & Editor

  Last week in Orlando, FL, Schneider Electric hosted its first Global Software Customer Conference since it acquired Invensys in January. The conference has its roots as WonderWorld, the former Wonderware company’s own user conference. Over the years, after Invensys acquired Wonderware, the conference evolved into OpsManage, a global event that emphasized all of Invensys’ software, control, and safety offerings. Since Schneider Electric's purchase of Invensys, I have been waiting to hear some news about the integration of the two companies. That news, as it relates to software, was delivered last week at the conference.

In April of this year, Schneider Electric created a new business unit called Global Solutions. Global Solutions is made up of four key offerings. One of those offerings is Software, which will continue to be led by Ravi Gopinath as Executive Vice President. The Software business consists of the legacy Invensys brands—Wonderware, SimSci, and Avantis—as well as Schneider Electric’s Citect, Ampla, and OASyS DNA (Telvent SCADA) software brands, integrated into one business.
In addition to the Software business, Global Solutions consists of the following offerings:

• Field services and product support applicable to other Schneider Electric product offerings.
• Segments, activities related to industry-specific and key account level, global sales and after-market customer relationship management.
• Digital services, which is a basket of offerings that may or may not leverage software. Examples include cyber security risk assessment services and Telvent weather forecasting service.

Global Solutions and its President, Daniel Doimo, will be headquartered in Lake Forest, CA, which has long been the headquarters for Wonderware and the Invensys software business. Doimo stressed that software is a key pillar to Schneider Electric's global strategy. "We invested in software because we have the vision," said Doimo. "We don't want to reinvent the wheel - we want to spin it faster." Schneider Electric’s Global Solutions business will deliver holistic and integrated solutions to its customers. They are committed to tailored solutions for specific industry segments. Doimo and Gopinath believe the more robust, combined solution set offers the most comprehensive portfolio to help its customers achieve operational efficiency. However, Gopinath stressed, "We are always looking for opportunities to strengthen our portfolio through acquisitions."

Improving the user experience and driving additional value are the cornerstones of everything the company does. Gopinath said the software business has and will continue to focus incessantly on improving user experience, even as the customer persona is rapidly changing. Their second focus is interoperability, which is where architecture comes into play.

Software Architecture

At the core of its software solutions, and at the lowest layer of the architecture, is a common platform called Wonderware System Platform. It is the information management framework for all of the company’s software products. It is open, scalable, and secure, and it works across multiple hardware platforms. The second layer consists of applications that perform specific functions, like HMI, historian, MES, asset management, etc.  The third layer encompasses solutions for specific industry segments.


Prior to the Invensys acquisition, Schneider Electric introduced StruxureWare, a unique software platform of integrated applications and suites that delivers visibility into energy and resource use across an organization. The StruxureWare concept and name will be used in the newly combined software business. StruxureWare will be a collection of applications or solutions that are tailored to specific industry use cases.  They will provide specific, unique functions required by industry segments. A few of these StruxureWare offerings have been defined, but they are still early in the process of defining others.

Understanding The Programming Of The PLC

The programming of the plc is a procedure of making commands, arrangements, and measurements used by the PLC to make control on a machine or operation. The body of this process is the plc and the program is the brain.In fact, the programmed PLC makes a machine looks like a human. PLC stands for programmable logic controller.A PLC has begun in the 1960's by Modicon Company. 

Its initial application was in the cars production factories in which it removed the old relays and replaced it with the plc.

As usual, a better solution is always in a creative mind, though it was a simple decision and control system effective for the era. Quickly, a communication can be a mechanized switch operated by an electric supply to switch it on and off. 

Getting mechanized by nature is big compared to electronic devices and transferring components usually degrade and wear, and finally are unsuccessful. Producing the preferred relay common sense needs many relays and many more wires in order to connect them. Rewiring is needed if the logic is wrong or needs to be updated.

The PLC reduces many of these actual relays to create common sense which moves and circuits them almost to the software. PLC development has typically been and still at Step ladder Diagram or Step ladder Common sense. It continues to be mostly employed language for encoding a PLC, despite the fact that you will find choice spoken languages. The basic reason is, it is rather like the electric powered schematics employed for communicate reason.

Ladder reasoning is programmed using frequent power icons like those utilized for contacts and coils. A step ladder diagram program appears to be a power drawing that electricians are comfortable and familiar with, very easy adoption from the difficult-wired relays for the PLC was attained. Programming a PLC demands a certain knowledge and skill.

Comprehending the method that will be operated or programmed is paramount. Start-up and Shutdown characteristics tend to be overlooked or provided little focus at the start in which the concentration is in the principal features of the machine or process. The PLC should be picked to match the application as well as each one of the outputs and inputs accounted for and extras integrated in the event that the task expands or to deal with components that have been basically overlooked. Planning upfront will save time and frustrations later, as with all projects.

Getting together with all the stakeholders or those engaged might be a wonderful initial step. Hash out the range and establish a time-range and possess individuals included agreement to it. Later on, when extra features or characteristics are asked for, you can support the explanation of the coding task getting more than initially proposed.

PLC coding is only area of the whole job of automating a piece of equipment. An expert must layout and stipulates the ingredients that provide the PLC with its inputs and outputs that are going to control. If you are only responsible to programming the plc, so you need all the inputs and outputs lists and their specs from the engineer.

He or she will also be the main one to deliver a controlled narration or information from the project. Undertaken one step more in advancement, Boolean Reason diagrams might be provided to you the developer which can (if in depth adequate) be used to create the program. Quite often the Handles Electric Engineer will also carry out the programming and perhaps the HMI coding... but which is another subject.

So in wrapping it up, PLC programming is about giving brains to machines processes using a specialized computer and requires significant knowledge and skills. I will tell you it can be a very fulfilling job when it comes to struggle, constant studying, teamwork and last and positively not very least, monetarily get.

Enhanced motion control, safety and performance

Kollmorgen Automation Suite version 2.8 delivers new functions

With an embedded EtherCAT configuration tool, version 2.8 of the Kollmorgen Automation Suite (KAS) software accelerates the development of modular machine architectures.

The new release of the integrated development environment now enables users to build complete EtherCAT systems and configure all peripheral components, including HMI, I/O, controllers and motors, with a single tool. Along with ergonomic improvements, the resulting simplification makes life easier for system developers and boosts engineering efficiency.

One of the key innovations in Kollmorgen Automation Suite 2.8 is the embedded EtherCAT configuration tool, which makes it easy to integrate EtherCAT components (including those from other manufacturers) into the application. With this open architecture, Kollmorgen reduces development time for modular, multi-purpose machine architectures. Another clear advantage of this approach is that direct communication with Kollmorgen AKD PDMM servo controllers from PC-based applications is now possible using UDP and HTTP protocols.

EtherCAT, safety and visualisation: the new software release 2.8 of Kollmorgen Automation Suite (KAS) offers a variety of new functions for faster machine development.

Convenience is also enhanced by the incorporation of safety technology in the engineering process. For this purpose, the release integrates Kollmorgen's new KSM series of safety modules. These compact devices combine Safe PLC with Safe I/O in a single package and provide TÜV-certified functions up to performance level e of ISO 13849 or SIL 3 of IEC 61508.

Version 2.8 of the Kollmorgen Automation Suite also features performance enhancements for servo amplifiers. The user-programmable controllers in the AKD PDMM family form the core of KAS thanks to the "IPC inside" philosophy. Future devices feature twice as much capacity at rated currents up to 24 A and faster processors. Along with general performance enhancements, application options are expanded by the inclusion of new motion control functions.
