CPi Panel PC Lite Models are Upgrading to 32GB SD Cards
The standard SD card capacity for CPi Panel PC (Lite models) is being upgraded from 8GB to 32GB. Moving forward, Lite units will ship equipped with the Raspberry Pi 32GB SD card.
Why the Change?
The SD card market has shifted decisively toward higher capacities, rendering 8GB cards a low-volume niche, and a less desirable option.
Software Demands: Modern OS installations are increasingly leaving less room for additional data partitions on an 8GB card, forcing developers to make unnecessary comp

Introducing the New CFNET Field I/O
We are pleased to introduce our new CFNET Field I/O product.
This product has been in development for a very long time, and we are excited to finally bring it to market. The original concept behind CFNET began with MODPORT, a PC-based I/O product we released many years ago. MODPORT uses RS-485 and the Modbus protocol, which is still the most common approach used by many third-party field I/O products on the market today.
However, this approach has clear drawbacks. Users must implement the comm

Ladder Logic Isn’t as Hard as You Think
Ladder logic is a diagram-based programming language commonly used in PLC systems. If you’ve only worked with traditional programming languages like C or BASIC, ladder logic can feel unfamiliar—and honestly, a bit intimidating at first. Because of that, many people give up before they even start. But here’s a fun fact most people don’t realize: You already learned ladder logic back in middle school.
A Circuit You Already Understand
Think about the most basic electrical

What Makes CUBLOC Truly Different?
CUBLOC was released in 2004, a full year before Arduino entered the market. It is a product entirely developed by COMFILE Technology, from the compiler to the firmware. Unlike many platforms that rely on third-party toolchains or operating layers, CUBLOC was designed as a complete, vertically integrated system from the ground up.
A Well-Engineered Firmware at the Core
The greatest strength of CUBLOC lies in its well-designed built-in firmware, often described as an interpreter or even a lightwei
