First steps with CODESYS Git ^{hermsen blog (Blog Post)}
First steps with CODESYS Git This is in no way a complete overview on what CODESYS Git offers. It is merely meant as a primer to get you up and running with git on forge quickly. Git is a popular open source distributed version control system. Understanding and mastering the basics is easy. However, the best results are achieved via 'learning by doing'. This blog-post tries to condense the bare essentials for CODESYS Git so you can get started quickly. Be aware that Git is a totally different beast from svn! If you have previous experience with svn you will have a (small) head start in understanding the basic key concepts of Git. CODESYS Git usage requires a valid Professional Developer Edition or a Demo License (free). If the entire community (you all) will ask politely, CODESYS will surely consider enabling free usage for use with CODESYS Forge General Git terminology Git: 'global information tracker' or more commonly 'git', is a 'container name' for a source code repository Main: Since 2020 'master' is being replaced with 'main', in this guide we will use 'main' Remote main: The remote 'main' repository, which is usually hosted somewhere online or somewhere in your network and it contains the entire project code and it's entire history. Also referred to as 'origin' Local main: Usually a local clone from a remote main. The local clone is an exact copy of the remote main repository and acts a local starting point for your contributions Branch: A working branch or snapshot of 'Local Main' which acts as a startingpoint for you to add contributions in. Once you have tested the contributions (and stage/commit them), you can merge them back into your local main branch Merge : the act of 'merging' changes from source branch S into destination branch D. You should use this to update a local main with a development branch or to update working branches. Checkout: the act of selecting a new active working branch, the IDE will switch to this version so you can work in it Stage: the act of preparing files and code changes on the current checkout Commit: Adds staged files and changes into the current checkout branch. A username, emailadres and a commit message are to provided on each commit. The more descriptive your commit message is, the better as this will help you search for mutations if you need to without digging into the history too much. A good commit message could contain a version number, a ticket or sprint number/ message. Changes are always commited to the current checked out branch Push: commits from local branches are ultimatly merged into the local main. When you are satisfied with the result, e.g some feature or ticket is completed, the local main needs to be synchronised with the remote main. In order to di this we must 'push' all changes into the remote main. Pull or 'Pull request': A pull request can be sent to the admin of a remote main. This will notify the admin that a new code is ready to be merged into the remote main. After checking this new code the admin can decide if he merges it (partially or entirely). Sync: The remote main and your local main should ideally stay synchronised (have the same content) and should be synced on a regular basis. This is achieved by 'pulling' the remote main into local main and pull these changes into a working branch. In general, a synced main and working branch will ensure that merging changes back into main will not cause conflicts It is a good practice to update at least your local main after loading your project into the IDE, you can then decide to update your specific local workbranches if needed Never commit and push untested code into a remote main (or even a local main), always test your work beforehand! This also a reason why pull requests are popular as they also provide a (in theory) 4 eyes principle Flow: There are many ways or practices (flows) to use git, however there is no single best flow as this depends on many factors. In general a good flow mainly depends on group needs, group size and group growth. A good git flow will not cognitively drain you but helps you focus on development 'Pull Requests' and 'Squash' will be on the roadmap for an updated version Installing CODESYS Git Start the CODESYS Installer (Start > CODESYS > CODESYS Installer), Select the installation you wish to extend with git and press "Change", In AddOns select the browse category, Now enter Git in the search bar and start the search by pressing enter, Select it and press install and follow the instructions, Wait for the installation to complete, Ready! Typical git flow Initial setup is done a few times in the development cycle, but usually significantly less then the repeated flow, unless you like to tinker around much or you have a need for many git's Add cForge Git repository Add a new "Git" repository on a project where you are Admin via "Add New..." menu, Once the Git repository has been added to cForge, you can use it to check in and out code as your "remote main" Initial setup Initialise remote main git see [[## Add cForge Git repository]] Load project into CODESYS Initialise (create) local main git Stage/commit loaded project into local main Add remote main as a location in local main Push local main to the remote main Keywords: create remote, load project, create local, commit local, add remote, push remote Repeated flow Branch (copy) and checkout the local main into a new named branch for your first contribution, give it a descriptive name (e.g the goal of this branch) After completion, stage and commit the changes onto your current working branch Checkout the local main Merge the previous working branch into the local main, Stage/commit, Push local main into remote main, Ready! Keywords: branch/checkout, code, stage/commit, merge, push History overview This Tab shows an in depth historical overview of you current checkout working branch named "Dev_PrimaryHost" has been created from the local main In this branch, "FB_Payload_Old" has been deleted, staged and committed into "Dev_PrimaryHost" After this the branch has been merged with "Local Main" CODESYS svn to git migration Checkout from SVN Disconnect from SVN Git > Initialize Local repository Git > Remote > Add the remote git location you made in the previous step Git > stage/commit and push to the remote origin Messages pane Since CODESYS Git is a WYSIWYG editor, typing commands in a console window is unnecessary. The Message pane provides some detail on what is going on (not 1:1 commandline, but at least similar). Future CODESYS Git features I am not familiar with the roadmap, but an educated guess will surely be support for the following features listed here as most of these counterparts have been implemented in CODESYS SVN allready Free usage with CODESYS Forge, CODESYS Git SCRIPT API support, Create Pull Requests, merge --squash, blame, prune, rebase, clean, cherry-pick, bisect, Support for Git submodules, And more features for sure 😃

If you follow this recipe closely it "should" take you between 1 or 2 hours, depending on your experience. Need any help? -> Drop us a question below, we are happy to assist you. On choosing your Ignition SCADA Flavor It's up to you to decide which flavor of Ignition you wish to run as they are identical but differ in use-case scenario. The provided information is not intended as advertisement but merely to provide you with enough information for you to make a choice on what installation is best suited for you. Maker Edition Ignition Maker Edition has powerful industrial-grade features of Ignition Enterprise by Inductive Automation️® to any number of your personal or educational projects at no cost. All you need is a permanent internet connection for it to work (so called 'always connected'). This seems for most purposes the optimal choice. https://inductiveautomation.com/ignition/maker-edition for more information Enterprise Edition This is the full fledged version of Ignition Enterprise SCADA. Without proper licensing it runs in a DEMO trial period for 2 hours. The trialperiod can be extended an unlimited amount of times by a single push of a button. https://inductiveautomation.com/ignition/ for more information Required Software Components Host software Windows 10 https://www.microsoft.com/en-gb/software-download/windows10 WinSCP https://winscp.net/eng/download.php for copying files over from your local Windows 10 Machine (Host) to your Virtual Box Debian client CODESYS Development System V3 https://store.codesys.com/codesys.html CODESYS Control Win 64 CODESYS Gateway 64 CODESYS IIoT Libraries SL https://store.codesys.com/iiot-libraries-sl.html IEC SparkplugB library https://forge.codesys.com/lib/cobolt/home/Home/#download IEC SparkplugB example project https://forge.codesys.com/lib/cobolt/home/Home/#download MQTT.fx (optional) https://mqttfx.jensd.de/ Oracle VM VirtualBox https://www.virtualbox.org/wiki/Downloads Client Software Debian 10 https://cdimage.debian.org/debian-cd/current/amd64/iso-cd/ Mosquitto server (apt install mosquitto) Ignition https://inductiveautomation.com/downloads/ignition MQTT Engine https://inductiveautomation.com/downloads/third-party-modules/8.0.16 Installation This guide assumes you have Windows 10 and WinSCP already installed on a PC. Feel free to deviate in any way from this guide. * Download the latest version of all the components listed above: * With the CODESYS Development System V3 installer, CODESYS Control Win 64 and CODESYS Gateway 64 are also installed. * Once CODESYS Development System is installed, double click the IIoT Libraries SL package to install it. This has a 30 minute demo, which is reset when you restart the PLC. * Install mqtt.fx. This is an MQTT client, which also has a SparkplugB decoder. Handy for debugging. Install VirtualBox. Installing Debian Install Debian: Open Virtual Box Press File > Host Network Manager > Create. Then tick the DHCP Server Enable box. Then Apply > Close Press New, give it a name, and operating system Linux / Debian (64-bit). Press Next. Use recommended memory size, but more the merrier. Select “Create a virtual hard disk now”, Press “Create”, select the default hard disk file type, dynamically allocated. As it is dynamically allocated, make it as big as you want, say 50GB. You should now be back to the main VirtualBox window. Click Settings for the newly created VM. Under storage, select the empty CD drive, then the tiny blue CD next to Attributes > Optical Drive. Choose the option “Choose a disk File”. Choose the debian iso. Under Network, leave Adapter 1 as NAT. Add Adapter 2 as host only network adapter. Press OK to accept the settings. Press start to start your VM. If asked, hit “Start” on the start-up disk selection dialog The Debian installer opens. Select “Graphical install”… choose appropriate languages… choose the first network in the list Choose a useful hostname, maybe debian10-ignition-mosquitto Skip the domain name by leaving it blank Choose a top secret root password, that you can remember. Failing to remember means repeating all these steps again. Choose a useful full name, and then username. Don’t forget the username. Partitioning method: Guided – use entire disk … All files in one partition … Answer Yes to “Write the changes to disks?” Go get a coffee, or other 15minute task, while it installs… Choose the default package manager options. Choose whether to opt in to statistic gathering. Untick the desktop environment, unless you like that stuff. Untick print server. Tick SSH and standard system utilities. You could probably squeeze in another coffee at this point. Yes install to master boot record. Install to VBOX_HARDDISK Boom! You now have a Debian installation in a VM! Type the username and password you remembered from earlier to get to the terminal Update debian, install mosquitto and get the ip address If you are not logged in yet to your linux VM, login. su type your root password apt update apt full-upgrade apt install mosquitto //note that mosquit[t]o is misspelled, because they wanted to have two ‘t’s like MQTT does. nano /etc/network/interfaces now copy the lines for enp0s3 and duplicate for enp0s8, and change allow-hotplug to auto Press Ctrl+X to exit and Y to save. Press Enter to accept original file location. systemctl restart networking ip addr show enp0s8 take a note of the ip address, you will need this! Install Ignition Use scp from a windows command prompt to copy the installer to your linux box WindowsKey+R, type “cmd”, enter Use an scp command similar to: scp C:\Ian\install\ignition-8.0.16-linux-x64-installer.run user@192.168.56.103:ignition-install.run scp C:\Ian\install\MQTT-Engine-signed.modl user@192.168.56.103:MQTT-Engine-signed.modl Login to linux. su chmod +x ignition-install.run /sbin/useradd ignition ./ignition-install.run Give the user you added above (ignition) Default install location Press 2 for custom install Press y for modifying included modules Press n for every one of the default modules, except maybe OPC-UA and Vision. Press y for modify additional modules, then press y for install additional modules. The path is: /home/user/MQTT-Engine-signed.modl Type n for “Would you like to install additional modules?” Type y for “Are you finished modifying the modules?” Type y for “do you want to continue?” Type y for “Start Ignition now” Type y for “Install Service” Back in Windows, open a browser and navigate to http://ip-address:8088 Pick any flavour you like (Maker Edition has no time-out) Agree the terms Set up a memorable username and password Start Gateway: Once it starts, go to Config > System > Modules > Quarantined Modules > MQTT Engine > Install You now have an Ignition server with MQTT Engine installed. You did it! Running an application Start MQTT.fx to monitor the topics: If not already started, start your Debian10-ignition-mosquitto. No Need to login to linux. Launch MQTT.fx from Start menu or C:\Program Files\mqttfx\mqttfx.exe Press the gear to add your MQTT Server Press the + down the bottom to add a new Server Give it a profile name, the IP address of your mqtt server, generate a client ID, then press OK Press Connect Go to the subscribe tab, and subscribe to the following topics: spBv1.0/SparkplugBDevice/NBIRTH/+ spBv1.0/SparkplugBDevice/NDEATH/+ spBv1.0/SparkplugBDevice/NDATA/+ spBv1.0/SparkplugBDevice/NCMD/+ STATE/+ Switch the payload decoded by to Sparkplug Decoder Start Ignition, to wait for connections: If not already started, start your Debian10-ignition-mosquitto. No Need to login to linux. By default, Ignition MQTT Engine will automatically connect to the local MQTT Server, so this does not need setup. If you need to set it up, use http://ip-address:8088 > Login > Config > MQTT Engine > Servers > Create new or edit. The easiest way to browse tags is through designer. Login to http://ip-address:8088 then press the Get Designer button to download the installer. Once installed launch designer. If your Gateway isn’t there, Add Gateway > Manually Add Gateway and type in http://ip-address:8088 before pressing “Add Gateway”. You should now see the Gateway, click Launch to launch designer. Login. Create a new project Use the defaults, but give it a name and title. Looking at the tag browser, you should currently see no sparkplug nodes. Install the sparkplug library: Now go back to the folder where you downloaded everything. Double click the sparkplug library to open it. Press the filing cabinet icon “Save Project and Install into Library Repository” Configure the example project for your CODESYS runtime: Back to the folder where you downloaded everything. Double click the sparkplug example project to open it. These steps are CODESYS 101. You should do this for every example project you open: Cancel the initial dialog asking about updating compiler etc. Right click Device in the Devices view, And select “Update Device” Select the actual version of your PLC runtime and hit “Update Device”, wait for it do its thing, then hit “Close” Project > Project Environment > Set All to Newest > OK > OK If your PLC is not running, start it now from the system tray. If you haven’t purchased a license, the PLC will stop after 2 hours, and the CODESYS MQTT Client SL will stop working after 30 minutes. If this happens you will have to stop it and start it again. Double Click the Device in Devices Tree, and go to the communication Settings Screen. Scan your local Gateway, and double click your local PLC. (ProTip: If you want this much nicer view, Tools > Options > Device editor > Communication page > Classic mode) Open PRG_FB_EoN_Node, and change the server URL to the ip address of your MQTT server. As this is a private Mosquitto, we will change test scenario to 2 as well. Go Online with this icon: Yes: Hit F5 or press the play icon to run the application: After a few seconds you should see it ONLINE: Now let’s look at the log. Double click the Device in the device tree and go to the Log tab. If you do not have a license for the runtime or you do not have a license for the CODESYS IIoT Libraries SL, sou should see these messages: To access the sparkplug specific logs, press these buttons and select SparkplugB: You can change the verbosity of the logs with the verbosity param. Go Offline and open library manager, and browse through Sparkplug B MQTT > SparkplugB > GlobalVariables > GVL_Param_sparkplugB. Is everything working? Check in MQTT.fx, you should have some payloads: Check in Ignition Designer, you should have some new tags in tag browser, changing every 5 seconds (configurable): For more information on using CODESYS, go to help.codesys.com and forge.codesys.com/forge/talk/ For more information on using Ignition, go to inductiveuniversity.com and forum.inductiveautomation.com Need help? -> Drop us a question, we are happy to assist you.
