factory-x.io is a code generator for well structured and maintainable PLC/PAC/DCS logic.
- Programming industrial controllers is labor-intensive and often a very repetitive job.
- As with any other programming ecosystems it is prone to errors, however there are no automated testing frameworks.
- Functional and control logic is not separated, severaly limiting scalability, innovation and possibility to open-sourcing parts of the programs.
The input is an FDS/DA document in the format as specified by the customer or integrator. Open-source import-scripts translate the FDS/DA in a model (Model-A). Model-A is a json structure closely representing the FDS/DA.
Once Model-A is generated it is transformed into Model-T (T standing for Tranformed or Template-Model). The goal of this transform is to generate another json-model that is very easy to iterate over by a standard templating engine. This transfor is also the most complex part of the code generater, and running as an AWS Lambda service.
Finally Model-T is sent through a templating engine that creates the the controller logic. The code-generator is brand and language-independent. Generating code for a different type of controller or language is as simple as changing the templates.
This example has following templates:
- Siemens Step 7 STL (AWL)
- Codesys/Bedrock Automation Instruction List (PLCopenXML)
The project is currently in beta, with two pilot projects having been auto-generated for more than 90%, including phases and equipment modules. The templates for the pilots are Siemens S7 STL. (Not TIA)
See example project instructions below, and iterate from there. We're currently working on full documentation
We'll probably do it for free in return for a lot of user-feedback
Install the latest version of node.js for your system: (This include a javascript runtime and NPM: the most popular package manager at this moment)
https://nodejs.org/en/download/
Install git for your system:
Start up a terminal (Windows cmd, or powershell, or whatever yo prefer)
Go to the folder where you want to create the project
Clone the example project
git clone https://github.com/factory-x/fx-example fx-example
This will clone the project in the directory called fx-example
In this directory there is a directory for the model (fx-example/mode => this is where the FDS/DA is stored)
Unzip the example model in this directory:
https://s3-us-west-2.amazonaws.com/factory-x/model.zip
Go back to the terminal an make sure you're in the folder 'fx-example':
npm install
Install the CLI tools:
npm install factory-x-cli --save
finally render the project:
fx render
The result can be found in fx-example\output\plc and fx-example\output\model
From here on you can make changes to the templates and the model, Re-render with:
fx render
Finally import the project to the development environment:
The exported file can be found under fx-example\output\plc\PLC.awl
Start from an empty project, import the symbols, and then the awl source.
The standard PID-FB needs to be added.
The project is configured to work with following Control Modules library from Siemens: https://support.industry.siemens.com/cs/document/68679830/example-blocks-for-wincc-v7-and-step-7-v5-(for-s7-300-with-scl-and-s7-400-with-cfc-scl)?dti=0&lc=en-WW
Todo's for Siemens:
- Test the template
The exported file can be found under fx-example\output\plc_Bedrock\PLC.xml
- Start from an empty project
- Add a device (Bedrock SCC)
- Delete the application (keep the PLC Logic Folder)
- Select PLC Logic folder
- Menu > Project > Import PLCopenXML > select the PLC.xml file
Todo's for CoDeSys:
- Control Modules (Valve, Motor, ... ) are empty dummy project. You can insert your own standard by changing the config in Model.json
- Phase Type template: logic missing to write the Equipment Modules
- test the template
