Safety-related communication

Development of safety-relevant CANopen devices

The CANopen CiA 304 SRDO Add-on supports all services and functionalities according to the CiA 304 V1.0 - CANopen Framework for safety relevant communication. It enables the development of safety relevant CANopen devices or applications based on SRDOs(Safety Relevant Data Objects). The CANopen CiA 304 SRDO Add-on as a basis for implementations in the CANopen safety area has already proven itself in a large number of industrial applications.

To use the add-on module the CANopen Master Slave Stack or CANopen Manager Stack is required.

emCompress offers solutions to compress data for all kinds of embedded applications where size matters.

Reduced data size for storage and transfer is highly valuable in embedded systems. Reduced storage size minimizes the complexity and costs of systems by keeping memory requirements small. Reduced transfer size overcomes limitations of the bandwidth available to send and receive data.

Designed for embedded systems, emCompress can compress and decompress data even on smallest microcontrollers. emCompress is available in four editions, emCompress-PRO, emCompress-ToGo, emCompress-Embed, and emCompress-Flex that cover different compression applications. Each edition is optimized for its specific use to provide the most convenient way to compress and decompress data.

emCompress is written in well-commented ANSI C. It is independent of both compiler and target. In contrast to most compression libraries, it is not covered by an open source or required attribution license and can be integrated into any commercial or proprietary product, without the obligation to disclose the combined source.

emCrypt is a secure and efficient implementation of essential cryptographic algorithms specifically designed for embedded systems.

The embedded file system

emFile is a fail-safe file system for embedded systems and applications optimized for minimum memory consumption in RAM and ROM, for high speed, and for versatility.

The emFTP - FTP server is an optional extension which adds the FTP protocol to the stack. FTP stands for File Transfer Protocol. It is the basic mechanism for moving files between machines over TCP/IP based networks such as the Internet. FTP is a client/server protocol, meaning that one machine, the client, initiates a file transfer by contacting another machine, the server and making requests. The server must be operating before the client initiates his requests. Generally a client communicates with one server at a time, while most servers are designed to work with multiple simultaneous clients.

A common challenge for manufacturers of embedded systems is to guarantee a system's firmware can be updated in the easiest way, even under adverse conditions. To replace bugged code in the field or to enhance the features of deployed systems, SEGGER provides the ideal solution: emLoad, the bootloader for firmware updates.

Modbus Software

emModbus, SEGGER's implementation of the Modbus protocol, supports communication via UART (ASCII, RTU), Ethernet (Modbus/TCP and Modbus/UDP), and is capable to communicate with any Modbus compliant device. 

• Supports ASCII, RTU and Modbus/TCP (and UDP) protocol
• Sample applications for all protocols included
• Kernel abstraction layer: can be used with or without any RTOS
• Modbus/TCP can be used with standard socket interface and any TCP/IP stack

High performance USB-Device software

emUSB-Device is a high performance USB device stack specifically designed for embedded systems. The software is written in ANSI C and can run on any platform.

A variety of target drivers are already available. Support for new platforms can usually be added at no extra charge. 

EADING USB HOST STACK FOR EMBEDDED SYSTEMS

SEGGER's emUSB-Host is a USB host stack specifically designed for embedded systems. It implements full USB host functionality, including external hub support and optionally provides device class drivers. It enables developers to easily add USB host functionality to embedded systems.
