ACE1000 PROGRAMMING CONCEPT 3
WHAT IS CODESYS IEC61131-3 IEC 61131-3 is an IEC standard for programmable devices. CODESYS (by 3S-Smart Software Solutions GmbH) supports all IEC61131-3 programming languages. The CODESYS development system (IDE) offers integrated, user-friendly software platform to support the user in developing an automation application designated for an ACE1000 RTU. The ACE1000 CODESYS runtime system enables the automation program execution on an ACE1000 target RTU. The development system runs on PC and is available free of charge. The runtime license must be purchased for each ACE1000 RTU designated to run CODESYS automation programs. 4

CODESYS IEC61131-3 Programming Languages The IEC61131-3 standard defines 5 programming languages: Language Form Factors for deciding which language to use Ladder Diagram (LD) Graphical Electrical Flow, Universal language acceptance, Applications mainly using digital I/O and basic processing, Ease of changing code later Functional Block Diagram (FBD) Sequential Function Chart (SFC) Graphical Graphical Process Flow, Applications mainly using digital I/O and basic processing Sequential Process, Ease of maintenance by the final user Instructions List (IL) Textual Boolean, Simple, Speed of execution Structured Text (ST) Textual Calculative Ease of implementing complex mathematical operations, Ease of use by newer engineers, Speed of execution CODESYS offers also the Continuous Function Chart (CFC). 6
CODESYS IEC61131-3 Ladder Diagram (LD) Language Ladder Diagram (LD) - visually, resembles a series of control circuits, with a series of inputs needing to be valid ( true ) in order to activate one or more outputs. 7
CODESYS IEC61131-3 Function Block Diagram (FBD) Language Function Block Diagram (FBD) - a graphical language for depicting signal and data flows through blocks, these being reusable software elements. A function block is a program instruction RTU which, when executed, yields one or more output values. 8
CODESYS IEC61131-3 Sequential Function Chart (SFC) Language Sequential Function Chart (SFC) - a graphically oriented language which allows to describe the chronological order of particular actions within a program. These actions are available as separate programming objects, written in any available programming language. In a SFC they get assigned to "step" elements and the sequence of processing is controlled by transition elements. 9
CODESYS IEC61131-3 Instruction List (IL) Language Instruction List (IL) - an assembler-like, so-called accumulator orientated language where each instruction is primarily based on the loading of values into the accumulator (a form of internal cache) by using the LD operator. After that the operation is executed with the parameters taken out of the accumulator, the result of the operation again is available in the accumulator, from where the user should store it with the ST instruction. 10
CODESYS IEC61131-3 Structured Text (ST) Language Structured Text (ST) - a textual high-level programming language, similar to PASCAL or C. The program code is composed of expressions and instructions, allowing the development of complex algorithms. The text-based, non-graphical nature of the language, also runs much faster than the graphical languages. 11
ACE1000 CODESYS IEC61131-3 APPLICATION An ACE1000 CODESYS IEC61131-3 application is a standalone program which is activated by the ACE1000 firmware, either when the RTU is powered up or after the application is downloaded to the RTU. The ACE1000 CODESYS application is coded with one or more IEC61131-3 languages, and include calls to CODESYS libraries APIs and calls to ACE1000 IEC APIs library. Its executable is created by the CODESYS PC integrated development environment (IDE) and downloaded to the ACE1000 target RTU using: Directly from the CODESYS PC tool. ACE1000 Easy Configurator. ACE3600 System Tool Suite. 12
ACE1000 CODESYS IEC61131-3 PROGRAMMING BENEFITS ACE1000 IEC61131 CODESYS application is developed using the free of charge CODESYS development PC tool suite that provides: Flexible application development environment. Freedom of programming as different IEC61131 languages can be mixed within the same CODESYS project or within the same CODESYS program. The developer may choose the language that best suits his 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 ST and then made accessible, as a function block, in a FBD or LD program. High level of re-usability of code and portability of applications Excellent debugging and online programming. CODESYS can be extended by add-on products, available within the CODESYS Store. 13
