Fast-paced innovation in the embedded systems domain puts an ever increasing pressure on effective software development methods, leading to the growing popularity of Model-Based Design (MBD). In this context, a proper choice of modeling languages and related tools — depending on design goals and problem qualities — is crucial to make the most of MBD benefits. In this paper, a comparison between two...
It is well known that bit stuffing in CAN may interfere with error detection and, in particular, with CRC-based approaches, so that the residual error probability can be noticeably higher than the theoretical value. Encoding techniques that prevent the insertion of stuff bits in the payload of the frame are a simple remedy, which improves integrity of data exchanged over the network noticeably. A...
Although the basic Modbus protocol is based on the master-slave communication paradigm with a single master, along the years it has been extended in various ways, in order to provide additional features such as, for instance, the coexistence of multiple masters on the same TIA/EIA-485 fieldbus segment. The design of a master election protocol in this environment is seemingly straightforward and the...
