ILC Corporation (Headquarters: Marunouchi, Chiyoda-ku, Tokyo; President & CEO: Hideya Onishi, hereafter "the Company") is scheduled to release the latest version, Ver.2.07, of its embedded control development environment "INTALOGIC5" in early May 2026.
Product Overview: What is INTALOGIC5?
"INTALOGIC5" is an embedded software PLC compliant with the international standard IEC 61131-3, supporting a wide range of platforms from non-OS environments to Windows®/Linux®. It enables the control previously handled by conventional hardware PLCs to be installed as software on PCs and microcomputer boards, achieving both cost reduction and space saving.
This product consists of two components: the "INTALOGIC5 Editor" (development tool) and the "INTALOGIC5 Run" (control runtime). In addition to the interpreter method, it also supports custom native code methods.
Furthermore, it has a proven track record of being ported to various OSs and CPUs, including Linux, μITRON, VxWorks®, QNX®, and Windows.
■ Main Feature Enhancements
● Addition of POU Password Feature (Security Enhancement)
A password protection feature at the Program Organization Unit (POU) level has been newly added.
This prevents unauthorized viewing and modification of specific control logic and know-how, realizing the protection of intellectual property and enhanced security.
● Support for Multiple Instances on 1 PC (Improved Development Efficiency)
It is now possible to launch multiple INTALOGIC5 environments simultaneously on a single PC.
This significantly improves the efficiency of parallel development, comparative verification, and evaluation work for multiple projects.
■ Key Points of This Update
In this version, we focused on balancing the "security" and "development efficiency" required for control software.
While realizing a secure development environment with POU-level protection, we also support faster development and verification through the multiple instance capability.
■ Future Development Roadmap
Summer 2026: Planned expansion of IEC 61131-3 compliant features, such as variable support in LD (Ladder) language.
As a future direction, we will advance data type extensions and improve expressiveness to realize more advanced and flexible control development. We also aim to achieve high interoperability compliant with international standards, considering support for PLCopenXML and IEC 61131-10 XML formats, as well as interrupt task processing.
Furthermore, we will continue to provide a flexible control environment by expanding features like motion control, positioning, and various communications as plug-in software.
■ Benefits of Implementing INTALOGIC5
- Equipment miniaturization & space saving: Compact control equipment due to no need for dedicated hardware
- Shorter delivery times: Specification changes can be handled simply by modifying the ladder program
- Realization of high-value-added products: Supports original product development with built-in control functions
- Security enhancement: Secure development environment through control logic protection
