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 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 …

Recently, we’ve seen a steady increase in interest and purchases related to Comfile Studio. To better understand why, let’s first look at how PC-based HMI or UI software is typically developed today.Common Approaches to PC-Based HMI/UI DevelopmentThere are generally two ways to build PC-based HMI (Human Machine Interface) or UI applications.1) Build Everything from Scratch (Free, but Labor-Intensive)One option is to use Microsoft Visual Studio and write the entire application in C# f …

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 …

In the world of industrial computing, reliability is paramount. Yet, a growing trend in the manufacturing sector sees the integration of a rather unconventional component: recycled CPUs from cryptocurrency mining farms. While offering enticingly low prices, these units pose significant risks to any business operations. The Rise of Recycled CPUs in Panel PCs Following the decline of cryptocurrency mining booms, a surplus of used hardware flooded the market. Manufacturers in certain regions began …
