CANopen protocol stacks with LSS Fastscan

Emtas (Germany) announces the release of version 1.1 of their CANopen NMT slave and NMT master stacks. The latest feature of the stacks is the support for the Layer Settings Services (LSS) to handle the node-ID assignment and the configuration of the bit-rate via CANopen as defined in the CiA 305 specification.

AMONG THE LSS FUNCTIONS the detection and addressing of non-configured devices is the main task. Besides the traditional LSS mechanism, the offered stack supports the LSS Fastscan service, which is the latest introduced function in the CiA 305. This is recommended to be used in some CANopen specifications (e.g. in application profiles such as CiA 447 for add-on devices in special-purpose cars) released by CAN in Automation (CiA). Using the LSS Fastscan services the non-configured devices can be detected faster as with the usual LSS procedure. This accelerates the start-up of a dynamic CANopen network.
The CANopen Slave Basic stack version is meant for the development of CANopen NMT slaves with basic functionality. According to the company, the Master/Slave version can be used to develop CANopen NMT slave or NMT master applications with all features defined in the CiA 301 (CANopen application layer and communication profile) and NMT master features according to the CiA 302-2 (additional CANopen application layer functions – Network management). The stack is written in Ansi-C and conforms with Misra. The introduced LSS services are included in the scope of delivery of the stacks without additional costs. Customers within the provider-defined update period get this feature free of charge.
To ensure that the products meet the current state of standardization the company is member of CAN in Automation. As already in the passed years, the software developers from Emtas are active in various CiA working groups to participate in the development of the CANopen specifications, especially the CiA 301, CiA 302 (additional CANopen application layer functions) and CiA 305.
