5 Topic Overview Introduction to Unity Pro The Unity Pro configuration environment consists of several toolbars, browser windows and programming editors. Unity Pro allows the user to perform fundamental tasks such as creating, exporting and importing projects. Unity Pro is able to use the five IEC standard languages. These are Sequential Function Chart (SFC) language and four inter-operable programming languages: Instruction List (IL), Ladder Diagram (LD), Function Block Diagram (FBD) and Structured Text (ST). Unity Pro is a single programming software for four specialised hardware platforms: M340, Atrium, Premium and Quantum. With Unity Pro comes everything needed to program a complete control and automation system for its entire life cycle from, design, through debugging, operation, and maintenance. Unity Pro has the following features: Unlocated data independent of physical memory User-defined data types - Arrays and structures User-defined function blocks written in IEC-compliant language The ability to program independently of the physical module addressing Multi-tasking Unity Pro is able to simulate the operation of the selected PLC so that it is possible to run preliminary tests on programs without the need to be connected to a PLC. In addition this simulation allows users to test fault conditions without the need to make the devices fail. Unity Pro uses a graphical user interface. Many features of the use of such an interface should be familiar to users who have used other Windows programs.

6 Project Management Unity Pro allows the user to perform fundamental tasks such as creating, exporting and importing projects. Understand the different file types associated with Unity Pro, and each of their characteristics and uses. e.g. *.stu, *. sta, *.xef etc. When a project is exported, the software generates a XML format file with a.xef extension. This contains all the unprotected information: configuration of the inputs/outputs, sections, SR program modules, etc. Exporting is essential when upgrading to newer versions of Unity Pro. The project (*.stu) file from one version cannot be opened in a newer version of Unity Pro. Unity Pro allows a.xef file to be opened and thus import a complete project. This is particularly useful when upgrading to a newer version of Unity Pro. A project Archive is a highly compressed version of the project. The compression rate can result in a file that is more than one fiftieth the size of the STU file. Archiving is similar to exporting except that it saves the compiled application. The Project Browser allows the contents of a Unity Pro project to be displayed and to move around its various elements. The project can be displayed in two different ways: Structural View - a directory tree of the PLC structure Functional View - a way of displaying the PLC code by emulating the plant layout.

7 Controller Programming The International Electrotechnical Commission (IEC) has defined the standard IEC for programming languages in programmable controllers (PLCs). Five programming languages have had their syntax and semantics defined so that every vendor uses the same language. The languages consist of two textual and three graphical programming tools: Textual: Instruction List (IL) Structured Text (ST) Graphical: Function Block Diagram (FBD) Ladder Diagram (LD) Sequential Function Chart (SFC) Understand each of the Tasks available within Unity Pro and their purpose and priorities: Master Fast Auxiliary Event Understand how tasks are broken down into Sections, which are autonomous programming entities, for example, the block of code to control a pump can be written into a single section. Unity Pro is supplied with over 900 in built functions. These are: Elementary Functions Elementary Function Blocks Be able to use Variables, remembering that Variables exist in most, if not all, programming languages. A variable is a symbol or a name that represents a value. It is good programming practice to have a naming convention for the variables. These exercises use a simplified system. The names will contain only the device and action or device and status.

8 Test a Project Unity Pro provides tools to check the project for errors and to test the project as a simulation. The first step in testing the project is to Analyze for syntax errors. Any errors detected are displayed in the information window at the bottom of the screen. The second step is to simulate the project using the built in simulator. The PLC Simulator, built into Unity Pro, enables the use of a PC terminal to test the application program for M340, Premium, and Quantum PLCs without connecting to the PLC Processor. Understand how to start and use the PLC Simulator, how to Analyze, Build and troubleshoot an application. An Animation Table is a tool that is used online to determine the value of a variable. They also have the ability to force and modify changes in variables and are, therefore, a very useful tool for debugging and testing projects.

9 Languages: FBD, LD, ST, IL, SFC Each of the 5 IEC languages implemented within Unity Pro has their own set of features and characteristics. They are also equipped with individual toolbars and programming windows. Be familiar with the characteristics and implementation of each programming language. Ladder Diagram (LD) language is a very commonly used method of programming PLCs, it is based on the use of ladder diagrams. Writing a program is then equivalent to drawing a switching circuit. The ladder diagram consists of two vertical lines representing the power rails. Circuits are connected as horizontal lines, which are the rungs of the ladder, between these two vertical lines. Structured Text (ST) language looks like a high-level computer programming language such as PASCAL or C. A Control Engineering survey indicated that of all the IEC61131-defined programming languages, Structured Text has seen the greatest increase in adoption. This language perhaps best embraces the growing complexity of PLC programming, such as the process control functions. This is the mostly used now in automation, especially by new engineers. Instruction list (IL) programming is defined as part of the IEC standard. It uses very simple instructions similar to the original mnemonic programming languages developed for PLCs. It is the most fundamental level of programming language and is generally not used on a day to day basis, but is normally found within Function Block or DDT s. Function Block Diagram (FBD) is a graphical language that was designed to represent a circuit board. This was so that the users, who generally came from an electrical or electronics background, would be familiar with the symbols and expressions. Sequential Function Chart (SFC) language is a graphical method of organising a program. The Function Block Diagram was used to program a single object such as the pump. The Sequential Function Chart is used to program the overall process.

10 Graphics An operator-screen tool is integrated into Unity Pro. An operator screen gives a graphical representation of the plant and is used for the debugging, start-up and maintenance of automated processes. The operator screens provide a set of information (explanatory text, display of dynamic values, push buttons and summaries) allowing users to take quick and simple action to modify and dynamically monitor PLC variables. The operator screens editor provides all the HMI (Human/Machine Interface) elements needed for animated viewing and design of processes. When the PC running Unity Pro is connected to the PLC, the user can display screens dynamically depending on the state of the process. Whilst in online mode, operator screens enable direct access to the Unity Pro application program from summaries by simply clicking on the selected object.

11 Trending Tool The Trending Tool is a powerful tool designed to help the user monitor production resources on a daily basis. The Trending Tool enables the user to obtain an accurate representation of how the production installation is operating. It is possible to select the relevant variables from all those available in the system and place them in your application with a few simple clicks. Within a few minutes, the first configuration is created and the data associated with the variables is ready. Once the work is saved, the recording is available on the computer's hard disk. Understand the properties of the Trending Tool window, including: Variables Modules Recording Trend Curve Property Screens Understand the possible methods to review the data: Saving the recording Opening the recording Printing the recording Exchanging the data with another application Each method is easily achieved and allows the user a quick and simple method to access and review process information.

12 Function Blocks In addition to Elementary Functions, the FBD language of Unity Pro also uses Elementary Function Blocks and Derived Function Blocks. In Unity Pro, the abbreviation FFB (Functions and Function Blocks) is a generic term to represent: Elementary Functions (EF) Elementary Function Blocks (EFB) Derived Function Blocks (DFB) Understand the different types of function blocks available within Unity Pro, the methods to implement and the advantages of each. Elementary Function Blocks (EFBs) are similar to Elementary Functions except that they have internal states, that is, even if the input pins have the same values, the value at the output pin can be different for every execution. Derived Function Blocks (DFBs), have a structure identical to that of EFBs but are created by the user with one or more of the programming languages FBD, ST, LD or IL. A DFB type can have one or more instances. Each instance is referenced by a name (symbol) and possesses DFB type data. User-defined EFs and EFBs can be created using the Unity Pro EFB Toolkit option. The Unity Pro EFB Toolkit option integrates with Microsoft s C compiler.

13 Project Maintenance and Documentation Good programming practice includes purging the libraries of any unused code when it is no longer used and to include documentation in all projects. Purging the unused code has advantages such as freeing memory. Documentation should be written so that everyone who will gain access to the program will understand the functionality. Understand the various methods to maintain the project. The Unity Pro Library contains all available objects to develop an automation project. These objects may be the following functions or variables: EF (Functions), EFB (Function blocks), DFB (user function blocks), The Type Library Manager provides functions to edit the contents of the library and execute transfers between the library and the project you are working on. It is advisable to purge FFBs (Functions and Function Blocks) occasionally using the command available in the Libset contextual menu OR Tools» Types Library Manager. Programs for PLCs can involve hundreds of sections making it difficult for future navigation and troubleshooting. The Functional View of Unity Pro is one of the tools provided to assist users to navigate within the project. It is good programming practice to include documentation in all projects. Good documentation allows users to understand how a project is structured the next time anyone needs to quickly make modifications. Documentation should be written so that everyone who will gain access to the program will understand the functionality.
