Opto 22 adds IEC 61131-3 to groov EPIC edge programmable controller

Monday June 24, 2019
June 24, 2019 – Opto 22 has added international standard IEC 61131-3 programming options in its groov EPIC edge programmable industrial controller.

To take advantage of this new programming option, current groov EPIC owners can install a free upgrade. 

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 Development System is available at no charge. 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. 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 optimized for edge data processing and communications.
