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.

CODESYS ‘IEC61131-3’ Programming Languages

The IEC61131-3 standard defines 5 programming languages:

CODESYS offers also the Continuous Function Chart (CFC).

6

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)

Graphical ‘Process Flow’,

Applications mainly using digital I/O and basic

processing

Sequential Function

Chart (SFC)

Graphical ‘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

RDS1048


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

RDS1048


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

RDS1048


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

RDS1048


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

RDS1048


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.

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

RDS1048


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.

ACE1000 CODESYS ‘IEC61131-3’ PROGRAMMING

In CODESYS PC Development System , program an application to be executed by

the ACE1000 RTUs.

The application can use various system functions from the ACE1000 ‘IEC’ library,

such as database access, I/O sampling and activation, comm. between RTUs, etc.

4. Connect to ACE1000

1. Create a CODESYS project & configure ACE1000 I/O mapping

2. Write an ‘IEC61131-3’application

The steps are detailed in the ACE1000 IEC61131-3 Developer's Guide

RDS1048


PROGRAMING AN ACE1000 ‘IEC61131-3’ APPLICATION STEP 1

Creating the CODESYS Standard project for Device=ACE1000 (MotorolaSolutions) and the

preferred IEC61131-3 language:

21

RDS1048


PROGRAMING AN ACE1000 ‘IEC61131-3’ APPLICATION STEP 1 (Cont.)

RESULT: A new project is opened with main board I/O objects as default 3DI_1DO

22

RDS1048



(Cont.) STEP 1 (Cont.)

Defining the execution of the application program:

23

Offline mode:

Configure the application’s ‘Main Task‘ priority to 16,

Type to cyclic and interval to 2 sec.

Online mode:

Adjust ‘Main Task’ interval to Max. Cycle Time (μs).

RDS1048



24

Adding I/O devices:

for the use of applications that refer to

the objects on the I/O modules

configured for the ACE1000 RTU

RDS1048



Edit I/O Mapping: link inputs/outputs logical names to physical inputs/outputs

channels.

25

RDS1048



Write an IEC Application: Create an application (‘PRG’) using one IEC61131 language or more and call the relevant ACE1000 ‘IEC’ APIs.

26

RDS1048



Build an IEC application: convert the source

(symbolic) application program to a compiled

program code that can be executed by the RTU

(correct any errors).

To a later download of the application via

Web/STS (step 5), use the Online ‘create boot

application’ to save (*.app,*.crc) files.

27

All the application’s objects are syntactically checked

RDS1048



Scan network and connect to ACE1000: setup the communication via the PC as

gateway to the target ACE1000 RTU.

RDS1048



30

Online Users Management: • A non-secured user that online logs into the ACE1000 target RTU is identified as ‘nobody’

• The ‘Security’ menu enables adding/removing secured online users with names and passwords.

• To remove the last secured online user add a user by the name “Everyone” and an empty password

RDS1048



Debug application: the user which is currently online logged into the ACE1000

RTU can evaluate programming errors using the CODESYS debugging

functionality in online mode.

31

RDS1048



Monitor application: the user which is currently online logged into the ACE1000

RTU can monitor the current values of the running program expressions

32

RDS1048



(Cont.)

Simulate application: run and debug the application on a "simulation target" which

is always available within the CODESYS development system (excluding the

ACE1000 ‘IEC’ APIs).
