CB280 (CUBLOC Core module)

CUBLOC Core Modules provide PLC-like functionality in a compact, embedded form factor. They support Ladder Logic programming commonly used in traditional PLC systems, while their small physical size allows developers to design fully customized PCBs tailored to specific applications.

In addition to Ladder Logic, CUBLOC modules can execute BASIC programs simultaneously through on-chip multitasking. This makes it possible to combine real-time I/O control with structured program flow, data processing, and communication handling within a single controller.

This hybrid control architecture is ideal for industrial automation, custom control equipment, OEM products, and embedded systems that require reliable PLC-style control without the size and cost of a full PLC.

FAQ

Q: When was CUBLOC developed, and is it reliable?

A: CUBLOC was first released in 2004, well before platforms like Arduino became popular. Over the past 20 years, it has been continuously maintained and refined through steady updates. In South Korea, CUBLOC has become a widely adopted and proven embedded controller, used in a large number of commercial and industrial products.

Its long history and large installed base are strong indicators of reliability. In fact, over the past five years, only minimal patches have been required—simply because the platform has reached a high level of maturity and stability. In short, CUBLOC is not an experimental or short-lived platform. It is a time-tested, stable solution that you can use with confidence. 

Q: I have experience using standard PLCs, but I’m not familiar with BASIC. Can I still use it?

A: Yes, absolutely. You can start by using just a minimal amount of BASIC—only enough to enable the ladder logic—and then build your entire system using ladder logic alone, just like a traditional PLC.

That said, CUBLOC really shows its full strength when BASIC and ladder logic work together. This combination allows you to achieve much higher efficiency and flexibility than ladder logic alone.

The good news is that BASIC in CUBLOC is not difficult to learn. You can begin by completing your system with ladder logic right away, and gradually learn and incorporate BASIC over time as needed. In short, you don’t have to learn everything upfront. You can be productive immediately—and grow into the more advanced features at your own pace.
