Have you ever been stuck on a coding problem? Unsure of which tool to use for an application? Or if you have the functionality you need to get the job done? Maybe you’ve just got a new system and need a map to help you learn the new features and functionality.
As a developer, you need reference material to find your way around. Whether it’s official documentation, Stack Overflow, a forum thread, or someone’s shared code, having the right resources can make the difference in getting something working, saving development time, or just making a more efficient application.
These resources and references are even more important when working with a new system, and with groov EPIC there are a ton of programming options — so it’s critical that developers have a clear picture of which tools are available, what they are capable of, why they have been included, and when to use one over another for a specific task.
To give developers a go-to resource for developing with groov EPIC, we’ve put together a new section of the Opto 22 developer site for all things EPIC to help provide the resources that developers like me want and need while working on applications.
Here are some of the main points that can be found in the new guide for developing with groov EPIC:
- Secure Shell (SSH) for access to the core Linux operating system, and all the custom programming options that can come with shell access like Python, C++, bash scripts, and more. In this section, we also cover software repositories and how the groov EPIC repo compares to that of other Linux distributions.
- REST APIs that provide HTTPS access to controller tags and data. We go over what each can provide and also cover how to get started with our Swagger reference.
- OptoMMP, the underlying memory-map protocol for every Opto 22 controller, including groov Using sockets and arrays of hexadecimal values, this method provides powerful high-speed communication and control.
- IEC 61131-3 for control programming in ladder diagrams, function blocks, sequential function charts, and structured text through the CODESYS development environment.
- Ignition Edge with external PLC drivers for Allen-Bradley, Siemens and ModbusTCP.
- MQTT/Sparkplug for communicating device I/O and variable data over secure sockets using an MQTT broker.
- Node-RED JavaScript-based flow programming tool that provides connectivity between Internet of Things (IoT) devices, cloud services like databases and APIs, and much more.
As well as descriptions of these methods, there are new pages with more details for Secure Shell (SSH), REST APIs, Python, and SSL Certificates for Browsers.
