February 7, 2019 – Opto 22 announces the addition of international standard IEC 61131-3 programming options in its groov EPIC edge programmable industrial controller. Adding these programming options to the existing flowchart and custom user-written options in groov EPIC gives control engineers the ability to program using a variety of languages they already know, while taking advantage of the EPIC’s extended capabilities for automation and industrial internet of things (IIoT) applications. All IEC 61131-3 standard languages are supported by groov EPIC, including Function Block Diagram (FBD), Structured Text (ST), Sequential Function Charts (SFC), and Ladder Diagram (LD).
Adding the IEC 61131-3 option gives engineers several key advantages. First, they can pick the best software tool for their specific application. Second, they can mix and match several software tools to build control and IIoT solutions on one unified platform. And last, companies can continue to leverage existing employee knowledge in IEC 61131-3 programming methods, including decades-old ladder logic.
The PC-based CODESYS Development System V3 is used to create and compile IEC 61131-3 programs for download to a pre-installed CODESYS Runtime running on groov EPIC. The CODESYS Runtime on groov EPIC is enabled by a free software license available from Opto 22.
In addition to IEC 61131-3, groov EPIC can also be programmed using Opto 22’s native PAC Control™. Field-proven, flowchart-based PAC Control with optional scripting offers 400+ plain English commands for analog process and digital sequential control, complex math, conditional branching, string handling, and other complex functions.
Other programming options include using software languages supported on the Linux operating system through secure shell. This access—along with toolchains and interpreters for Java, C/C++, Python, JavaScript/Node.js and more—allows developers to create custom applications. In addition, groov EPIC includes Node-RED as another programming option. Node-RED uses a flow-based development environment for edge data processing and communications.
groov EPIC integrates the HMI software groov View with its control programs. Once an IEC-61131-3, PAC Control, or custom software application is developed, the control program's tags and I/O are available for building a groov View HMI. Data from other systems and equipment on premises, at remote locations, and in the cloud can also be included in the HMI.
Authorized users can view this HMI to see data and control processes on the integral, industrial-grade color touchscreen display on the front of the EPIC processor. They can also view the HMI on an external HDMI monitor, and from any web browser or mobile device.
