software Programmable Logic Relay OPTA
Discover all the software currently available.
To meet the diverse needs of industrial design and automation, the OPTA Programmable Logic Relay offers two distinct programming paths, each supported by specific software. The choice of development environment depends strictly on the hardware in use and programming preferences.
For those who require an approach that complies with established industry standards, OPTA Codesys is the ideal solution. This device integrates the Codesys runtime, the world’s leading development environment for PLCs. By downloading the appropriate package, you can access a single design, testing, and debugging environment that supports all five languages of the IEC 61131-3 standard (ST, LD, FBD, SFC, and IL).
It is the preferred choice for experienced automation programmers who want advanced simulation and visualization tools in a hardware-independent ecosystem.
If the project is based on the versatility of the open-source world, the OPTA Arduino Pro range offers unprecedented flexibility through two main software options: Arduino PLC IDE, a dedicated environment that combines the power of PLC programming (IEC 61131-3) with the integrity of the Arduino system, and Arduino IDE.
The classic solution for those who prefer to program using “sketches” in C++ language, taking advantage of the community’s extensive libraries and native integration with the Arduino Cloud ecosystem.
