0:05 Hello, my name is Dorit Kliger and I am a senior software engineer in the Industrial IOT development group in M S I L.
0:15 The ACE1000 RTU can be programmed by an experienced Linux and IEC61131 language programmer to create a customized RTU that addresses his needs.
0:29 This webinar introduces to the viewer how to program a user ACE1000 automation application using any of the IEC61131 languages by choice, install it to an ACE1000 target RTU and debug it as it runs as a separate Linux process within the RTU.
0:48 The IEC61131 application software is integrated with the ACE1000 Linux based system software running in the RTU. An integrated IEC61131 application may use various system software functions that allow access to the CPU resources and RTU’s database tables, scan of the IO modules, communication handshaking and other system operations.
01:18 Each IEC61131 application downloaded to the RTU runs as a standalone Linux process. A newly downloaded application replaces an existing file of the same name, if such exists. Both MOTOROLA ACE STS and ACE1000 Easy Configurator WEB tool include the option for downloading a single IEC61131 application to the ACE1000 target RTU.
01: 49 CODESYS (an acronym for controller development system) is a development environment for programming controller applications according to the international industrial standard IEC61131-3. All five programming languages for application programming defined in the IEC61131-3 are available in the CODESYS development environment.
02:10 The free of charge CODESYS Development System (IDE), running on a PC, offers integrated, user-friendly platform to support the user in developing an ACE1000 automation application. The licensed CODESYS runtime engine running within the ACE1000 target RTU, executes the automation program downloaded to the RTU as a standalone Linux process. A customer that wishes to run an ACE1000 CODESYS automation application needs to place an order in Motorola’s ordering system for RTUs with the IEC611311 license installed on them.
03:00 Please access CODESYS official web site www.codesys.com to acquire more information about CODESYS components, support and trainings. The CODESYS Store is an online platform, where free and charged extensions for CODESYS from 3S Company and third-party vendors are offered for download and subsequent licensing, installation and rating. Another resource for CODESYS high quality online training is the BE.educated e-learning platform from Be.services.
03:35 The IEC international standards organization identified five standard programming languages that have emerged as the most common, used for both process and discrete programmable controllers. These languages common abbreviations are: Ladder Diagram (LD), Instruction List (IL), Function Block Diagram (FBD), Structured Text (ST) and Sequential Function Chart (SFC).
04:10 CODESYS supports also the Continuous Function Chart (CFC) Language which is an extension to the IEC 61131-3 standard. It is a freehand graphical programming language based on the Functional Block Diagram language, allowing free positioning of graphic elements. Language types can be mixed within the same project or in some cases, within the same program. This flexibility enables developers to choose the language that best suits their level of programming proficiency, and programming style, and the nature of the application itself.
For example, in a typical application, a custom function could be programmed using structured text and then made accessible, as a function block, in a Functional Block Diagram or a Ladder Diagram program.
05:05 The Ladder diagram language may be the most widespread language. It can be seen as a set of connections between logical checkers and actuators. The logic in a ladder diagram typically flows from left to right. The diagram can be divided into sections called rungs, which are roughly similar to the rungs on a ladder. Each rung typically consists of a combination of logical checkers instructions. These instructions lead to a single actuator instruction; however, rungs containing function block instructions may be more complicated
05:50 The Function Block Diagram language resembles a wiring diagram where the function blocks are “wired” together into a sequence that is easy to follow. It uses the same instructions as Ladder, but visually is more understandable to a viewer who is not versed in relay logic. This language is ideal for simpler programs but not for large programs.
