[hemmerling] IEC 61131 Process Logic Control Programming PLC - PLC Systems, PLC Hardware, PLC Software
The IEC 61131-3 Languages and its Programming Concepts
- Function vs. function block ( Funktionsbaustein ), with PC WORX:
- A function has an input and output variable, but does not allocate memory. So it has no internal state.
- A function block has an input and output variable, and can allocate memory ( uses memory ). So it might have an internal state.
- Forcing and overwriting of values is useful during the project phase “Bringing into service”.
- With “Structured Text” (ST), you don´t define PLC variables!

CoDeSys 2.3
- Version 2.3 running on Windows, with support for PLC / SPS with 8-bit CPUs. As of 2015-09, the latest editions are “CoDeSys 2.3.9.47”, available at 3S-Smart Software Solutions GmbH "Download".
- Simulation:
- The visualation within the CoDeSys IDE is available in simulation mode.
- The webbased visualisation is just available by the webserver running on the PLC hardware, not by the CoDeSys IDE on Windows.
- You may not write on input variables during simulation.
- IDE tips:
- Even if there is no item selector ( e.g. a button ”...” ) for an input field, in most cases pressing F2 opens the select window, when the cursor is in the input field.
- To edit a variable, address it with the mouse cursor, and press “SHIFT F2” to open the window “Declare Variable”.
- Task configuration:
- Experts told me that it might be useful to let a Modbus protocol run as 2nd. task.
- You might use tasks for developent, to define and simulate the behaviour of external hardware: One task simulates the hardware, the other one - the later PLC application - may control the hardware simulation and react to behaviour of the simulation. Inter-task Communication might be done by global variables. But it might be tricky to let simulation and later PLC application run concurrently, so that they work properly together.
- Create a new program: “New block”.
- Type of block: “Program”.
- Language of block “FUP”.
- Name of block “PLC_PRG” ( it's important to use this name for the first program which shall be executed ).
- Create a new visualisation: Name of visualisation “PLC_VISU” ( it's important to use this name for the first visualisation ).
- Function blocks - Use “VAR_INPUT” and “VAR_OUTPUT” as input and output variable types.
CoDeSys 3.5
- Version 3, running on Windows with .NET, no support for PLC / SPS with 8-bit CPUs.
- Available at 3S-Smart Software Solutions GmbH "Download".
- Supports object oriented development. In addition to the “IEC 61131-3” programming languages supported by V2.3, it also supports “Continuous Function Chart” ( CFC ).
- “Skriptsprache Python in CODESYS V3. Ab CODESYS V3.4 SP3 können Sie Abläufe innerhalb von CODESYS automatisieren. Dazu wurde ein Runtime sowie eine Systembibliothek für Python integriert. In diesem Forum finden Sie allgemeine Hinweise und Beispiele, auf die Sie bei der Erstellung von Python-Skripts zugreifen können”
Web Server of CoDeSys 2.3 and CoDeSys 3.5
- The CoDeSys 2.3 PLC web server requires Java on the client, i.e. a working Java 8 plugin installed in your browser.
- The CoDeSys 3.5 PLC web server is based on HTML5 and so doesn´t require Java on the browser client.

MULTIPROG PRO+
Projekt+
- PHOENIX-CONTACT "Planning and configuration" - The commercial planning tool “Projekt+” ( with “k” like in the German word ).
SAFECONF
- The free development and configuration software SAFECONF for Windows.
- Argumentation of experts:
- You mustn´t use a safe PLC anymore, e.g. SIEMENS “F-Systems” / “F-Steuerung”.
- You are not stuck with a special fieldbus.
- You may do safety control on the local floor shop, without any special fieldbus. E.g. safety light grids may be equipped with an OSSD interface instead of a fieldbus interface.
- Rockwell Automation "Schutzmaßnahmen und ergänzende Einrichtungen" - “Wenn einer der Strahlen durch Eindringen in das Abtastfeld blockiert ist, schaltet der Steuerstromkreis des Lichtgitters seine Ausgangssignale aus. Das Ausgangssignal muss zum Ausschalten der Gefahr verwendet werden. Die meisten Lichtgitter sind mit OSSD-Ausgängen ausgestattet (Output Signal Switching Devices – Geräte zum Schalten von Ausgangssignalen). Die OSSDs sind PNP-Transistoren mit Kurzschlussschutz, Überlastschutz und Querschlusserkennung (Kanal zu Kanal). Sie können Gleichstromgeräte wie Sicherheitsschütze und Sicherheitshilfsschütze mit bis zu 500 mA schalten”.
- With safe PLC systems, usually the vendors urge the clients to take a specific fieldbus for communication implementation:
- Bosch Rexroth → Sercos.
- Beckhoff → Etherreal.
- SIEMENS → Profibus & Profinet.
- With SAFECON, the standard fieldbus protocols may be used for communication with the PLC.
- However, SAFECONF is not applicable if a special safety fieldbus is implemented, e.g. “PROFIsafe” and “ASIsafe”.
- The safety function is transfered as before with traditional systems, back from the datacenter to the local shopfloor.
- Though the safe PLC model with same technical data costs just a little bit more, the safety control costs some performance, so that finally you must buy a bigger PLC ( which then doesn´t cost just little bit more than the non-safe PLC )
.
- PHOENIX-CONTACT "Configuration package - SAFECONF - 2986119" - “Configuration software for SafetyBridge technology and PSR-TRISAFE modules, connecting cable for PSR-TRISAFE”]].
Webvisit

The Express version is available free of charge and enables the creation of up to 10 visualization pages as well as linking a maximum of 60 PPO variables”.
IP Assign
- The free PHOENIX-CONTACT "IP Assign" for Windows - “IPAssign is an easy to use tool for setting the IP address of devices which rely on BOOTP”.
- BootP vs. DHCP.
- I was told by experts, that in a SIEMENS PCL network infrastructure, the BootP service is running permanently. Unfortunately, there the Highlander principle “There can be only one!” applies: There can be just one BootP server in a network segment.

- The installation of AUTOMATIONWORX Software Suite 2013 1.81” is refused on Win8.1 by the error message “Das vorhandene Betriebssystem wird nicht unterstützt. Das Setup wird abgebrochen”.
- The installation of AUTOMATIONWORX Software Suite 2013 1.82” fails on Win8.1 - The installation hangs during the installation message “Registering PC WORKX” and doesn`t complete.
- So I am waiting for 1.83.
- Some of the PC WORX libraries may also be used with PC WORX Express, but according to PHOENIX CONTACT staff members, are not shipped with PC WORX Express. So PC WORX Express users, please think about additional temporary installation of the demo version of PC WORX to transfer some libraries to your PC WORX Express installation ( e.g. CAN-Bus, Modbus,.. ).

PCS7 vs. TIA vs. Logo!
Experts told me:
| Hardware Technology | Platform & IDE | Features | Comments |
|---|---|---|---|
| S7-400 | PCS7 | “Large” RAM memory, A/D interfaces, strong FPU to process “floating point” data. The CPU is not higher-clocked than that of a S7-1500 & S7-300 | High-end hardware for process automation. Suitable for processing of large amout of analog data |
| S7-1500, S7-300 | TIA | Fast CPU, short PLC cycle time | High-end hardware for factory automation. Suitable for fast processing of digital data, no focus on processing analog data. Not suitable for process automation! |
| S7-1200, S7-200 | TIA | Low-end hardware for factory automation | |
| ET 200 ( ET200SP & ET 200S, ET200MP & ET200M, ..) | TIA | Decentral periphery for factory automation. CPU not mandatory, but without CPU the unit needs an S7-1500 system as master. If you build an ET200SP system with CPU, there is no cost advantage to an entry-level S7-1200 or even S7-1500 system | |
| ET 200 ( ET 200iSP ) | PCS7 | Decentral periphery for process automation. No CPU. Needs an S7-400 as master. | |
| Logo! | Logo!Software | Very low-end hardware, e.g for building automation | |

Siemens HMI
SIEMENS WinCC
-
- Simens "HMI System SIMATIC WinCC flexible" - for low-end visualisation is a .NET 2.0 software. The data size is limited by RAM memory.
- Siemens "SCADA System SIMATIC WinCC" - for high-end visualisation is a native Windows software. The data storage is file based, not memory based.
-
- “WinCC Sm@rt Server” ( formerly “Sm@rt Service”, “Sm@rt Access” ) → Access to SIEMENS PLCs with a browser.
- Be shure to terminate the WinCC ( server ) runtime application, on a WinCC device, by pressing a “shutdown” button on the screen, before switching off. If the WinCC application uses the CSV format to store logging data, there is the big danger that this logging file is lost, after poweroff without prior shutdown of the WinCC ( server ) runtime.
- I was told by experts, that the operation of WinCC applications on standard Windows computers often requires a Windows network with shared Windows network drives.
- Default usernames and passwords:
| WinCC version | Default username | Default password | Minimum password length |
|---|---|---|---|
| WinCC 7 and earlier | admin | 100 | 3 |
| WinCC 11 | Administrator | administrator | 6 |

Panels of 2014
- “Comfort Panel” and “Basic Panels” of 2014 follow different concepts:
- Both have a Flash memory, in which the current project runtime ist stored and executed.
- “Comfort Panel”.
- Default IP: 192.168.2.x, default password: “100”.
- Additionally, the “Comfort Panel” of 2014 have two SD card slots: 1 SD card for system data, 1 SD card with 2 GB data size for data logging. If there is a directory “SIMATIC.HMI” on the system SD card, it will be transfered to Flash during booting of the panel. Tip: You may keep different panel images on a single SD card, by renaming the directory ( but you can transfer just the panel image named “SIMATIC.HMI” to a panel ).
- 2x SD cards slots for SD cards with a maximum datasize of 2 GBytes each.
- 1 SD card for system data. Default filename for the system data: SIMATIC.HMI.
- 1 SD card for user data & data logging.
- “Basic Panel”
- Default IP: 192.168.4.x, default password: “100”.
- In opposite, the “Basic Panels” just have an additional USB interface. You may both use it for data logging ( but just of up to 10 variables ).
- You may copy the runtime data from the panel to a USB stick, for backup and transfer purposes.
- Additionally, you may store the small project runtime ( not the large full WinCC project ) in the expensive RAM memory of a Siemens 1500 PCL.
- 1x USB interface for data storage. Alternatively, the panel runtime can bei kept in the S1500 RAM memory.
- In the past, SIEMENS panels stored the full WinCC project. It was possible to restore the full WinCC project back to a Siemens WinCC developer computer. Now with the second panel generation of 2014, the full project is not stored anymore on the panel.
- SIEMENS users have often problems with keeping backups and ignore the needs for code version control... Siemens tries to help these users by new concepts like that of the second panel generation.
Panels of 2016
- For communications with “Comfort Panels”, the SOAP ( EN.Wikipedia "SOAP", DN.Wikipedia "SOAP" ) protocol is used. The Win7 running on the “Comfort Panel” makes use of “SoapUser” as required and forced Windows user name, for communications.
- I was told, that there is no default passwort anymore, with SIEMENS panels of 2016.

- With SIMIT, you handle faults, not the process / the plant.
- With SIMIT, you don´t write IEC language code. Indeed there is a C# script language to define setups of simulations.
- Hardware-in-the-Loop ( HIL ):
- Experts told me, that SIMIT can be used for Hardware-in-the-Loop ( HIL ) commnications test, as co-simulator!

The Tools, the Software
- The commercial service software tool SIEMENS "SIWAREX SIWATOOL", SIEMENS "SIWAREX SIWATOOL" for Windows.
Sample System Configuration
- A Windows PC ( 192.168.0.128 ), running TIA Portal and SIWATOOL, is connected by Wifi with an Access Point with integrated switch( no IP address ).
- The access point connects by Ethernet to
- PLC ( 192.168.0.1 ). This PLC is connected by Ethernet / PROFINET with a SIEMENS Comfort Panel ( 192.168.0.2 ) and the SIWAREX module ( 192.168.0.21 ).
- The SIWAREX module, by the 2nd. Ethernet jack. This second Ethernet interface might be operated by Modbus/TCP protocol or by the properitary SIWATOOL protocol. SIWATOOL can´t operate with Modbus/TCP, though...
- With old hardware, the SIWATOOl communications was not by second Ethernet, but by RS485.

- With the classical SIEMENS S7 development tool on “S7” PLC hardware targets, there may be just one OB1, which executed when the PLC is started.
- With the SIEMENS “TIA Portal”, several OB1 objects on “S7” hardware targets may be created. One of the many OB1 objects may be executed - one at a time, but not concurrently, so there is always just 1 task running -, when PLC execution is started.
- With the TIA Portal, new PLC function elements are “Technology Objects” for drive control:
- Positioning.
- Revolution speed control.

The Company & its Tools
-
-
- WAGO Ethernet StarterKits - may communicate with OPC servers, by Modbus Over Ethernet.
-
-
-
- In opposite to other websites, there are no static landing pages. So to find free application notes ( “Anwendungshinweise” ) and free software.
- So You must know what to search for, and enter the exact term. Global search engines like Google or Bing can´t crawl the database, so can´t help you with search.
- Especially the brief description displayed by search requests, is the only extra information available at all. With other websites, such information is available on static landing pages.
-
- “Modbus TCP” and “Modbus UDP” are the standard protocols for WAGO PLCs.

"CoDeSys 2.3" on PLC "WAGO 750-880"
Ethernet Options: 2-Port Switch or 2 single Ethernet Ports
- For WAGO 750-800 and most other variants, there is a 2-port Ethernet switch.
- WAGO 750-885, however, has 2 single Ethernet ports which are dedicated to operate in 2 different sub nets ( for security reasons ).
Windows tools for use on PLC hands-on Workshop "Introductory CoDeSys workshop", in 2015-09
- The commercial Windows software “CoDeSys 2.3.9.47”.
- The free Windows software “Ethernetsettings”, suitable for device configuration and setting-up operation.
- The commercial Windows software “IO-Check 3” ( is shipped with installer for “Ethernetsettings”, too ).
- It is suitable not just for device configuration, setting-up operation, but primarily for clamp configuration. You might do the same with self-written SMTP scripts.
- WAGO Programs - “WAGO-I/O-CHECK 2”.
Motor Control
Installation & Configuration
- For WAGO PLCs, there is a mode switch hidden under a cover:
- Top: Run mode. Necessary if you update and run PLC software, driven by the CoDeSys IDE.
- Middle: Stop mode. Necessary to run IO-Check in “Control Mode”.
- Down: WAGO-internal use only.
- A red dip switch may be used to configure the last octal of the IP address of the PLC web server, i.e. 192.168.1.x → 192.168.1.3. You may change the first 3 octals by the web interface, too.
- Webbased PLC management, login to the web server of a WAGO PLC - Username: “admin”, password “wago”.
Operation
- Boot process: “Bootp” is default.
- The BACnet PLC controller by WAGO forces a bootproject update. With all other WAGO PLC controllers, this update is optional.
Software Development
- There are 2 location for libraries, which may be imported and used in user-defined PLC software:
- Standard CoDeSys libraries ( “C:\Program Files\WAGO Software\CoDeSys V2.3\Library” )
- Target-specific libraries, created by the partner - the PLC hardware manufacturer - of CoDeSys ( “C:\Program Files\WAGO Software\CoDeSys V2.3\Targets\WAGO\Libraries” ). If a customer makes use of the special libraries, the application depends on this target and its PLC hardware manufacturer.
