The Emerson / Motorola MVME172 Series VME Embedded Controllers are based on the MC68060 or MC68LC060 Microprocessors. The I/O connection for the 400/500-Series serial ports is provided by two DB-25 front panel I/O connectors. The I/O is connected to the VMEbus P2 connector. The main board is connected through a P2 transition board and cables to transition boards. The Series 400/500 MVME172 supports the transition boards MVME712-12, MVME712-13, MVME712M, MVME712A, MVME712AM, and MVME712B. These transition boards provide configuration headers, serial port drivers and industry standard connectors for the I/O devices. The MVME712 series transition boards were designed to support the MVME167 boards, but can be used on the MVME172 by following some special precautions.

concept

Embedded controllers are a good and basic access device in Ethernet control networks.

An embedded controller is a control system used to perform specified independent control functions and has the ability to process data in complex ways. It is an electronic device or device controlled by embedded microelectronic technology chips (including a series of microelectronic devices such as microprocessor chips, timers, sequence generators, or controllers), capable of completing various automated processing tasks such as monitoring and control.

Embedded controllers are mainly used for real-time control, monitoring, management, or auxiliary operation of other devices. It consists of a microprocessor chip, software embedded within the chip, and other components.

Embedded controller software includes: embedded real-time operating system, application program, application programming interface API, real-time database, etc.

operational principle

Embedded microprocessor

Compared with general-purpose CPUs, embedded CPUs present a colorful scene, with over 100 types of 32-bit embedded CPUs in the world. Embedded CPUs mostly work in systems designed for specific user groups, with low power consumption, small size, and high integration, which is conducive to the miniaturization, intelligence, and close integration with network applications of embedded controller design.

Embedded operating system

Currently, popular embedded operating systems internationally include Microware OS9, Sun Java OS, Microsoft Windows CE, Windows NT Embedded, and free software RT Linux. China's Kaisi Group has also developed a universal embedded operating system, Hopen, with independent intellectual property rights.

network interface

The network interface provides necessary conditions for the embedded controller to access the network. The network interface is centered around a 32-bit CPU, and the controller completes the control function of the network interface. The communication interface includes RS 232C serial interface, communication protocol repeater interface, network interface, etc.

An Ethernet control network can be constructed using embedded controllers and network interfaces. With the support of distributed network computing platforms, a distributed control network can also be constructed.

Technical points

The operating system platform and network communication platform of embedded controllers are popular open platforms in the world today, laying the foundation for the openness of Ethernet control networks.

The operating system platform for embedded controllers, such as RT Linux, has strong functionality and fast and convenient application software development. The application software developed on the Linux operating system can run directly in the RT Linux environment, which means that developing embedded controller application software does not require a dedicated software development system and tools.

The powerful embedded CPU provides high-performance, high-speed processing capabilities, and flexible expansion methods for embedded controllers.

Supports TCP/IP protocol, making it easy to achieve network interconnection and expansion.

Various networks can be applied as embedded controllers to access the backbone network. These backbone networks have high communication rates, good real-time performance, and support distributed network computing to achieve network collaboration.

Embedded controllers, network interfaces, and distributed network computing platforms can not only build open systems

Single board computer, commonly known as SBC, is a computer that installs microprocessors, memory, and interface components on the same printed circuit board. SBC is a complete computer system that is completely contained on a single silicon board. Each SBC contains a CPU, GPU, chipset, and I/O port, all of which are soldered onto the board. Although additional components such as RAM, storage devices, or additional I/O ports can be added for more specific customization, the concept is the same. Because these components are all glued to one board, SBC is much smaller than most other motherboards, with the most standard being the common ATX appearance. SBC comes in multiple sizes, with two standard sizes being 2.5 inches and 3.5 inches, but their main selling point is that they are very small.

Although they are small, SBC is powerful. Not only can they handle and calculate complex tasks and data telemetry applications, but due to their small size, they are almost suitable for any embedded solution. Their size and powerful processing power make them a popular choice for rugged edge applications, where space is limited or system integrators use single board computers to design their own products. All products can be built around SBC and run regardless of deployment style. Due to their design approach, they offer astonishing advantages from low thermal design power (TDP) to industrial grade construction quality.

SBC single board computers have the advantages of low power consumption, high performance, high efficiency, simple integration, fast launch, withstanding extreme environments, and diverse I/O.
