RS-485, also known as TIA-485(-A) or EIA-485, is a standard, originally introduced in 1983, defining the electrical characteristics of drivers and receivers for use in serial communications systems. Electrical signaling is balanced , and multipoint systems are supported.
Modbus or MODBUS is a client/server data communications protocol in the application layer. [1] It was originally designed for use with programmable logic controllers (PLCs), [2] but has become a de facto standard communication protocol for communication between industrial electronic devices in a wide range of buses and networks.
ARINC 429 is a data transfer standard for aircraft avionics. It uses a self-clocking, self-synchronizing data bus protocol (Tx and Rx are on separate ports). The physical connection wires are twisted pairs carrying balanced differential signaling.
Restore power, speed and stability with over 200 critical tests and 50 tools using the go-to solution for ultimate PC performance and trouble-free computing.
System Mechanic is a performance solution that first deploys a series of complex automated maintenance actions to help keep your PC stable and clutter-free, and then goes to work by precision-tuning dozens of internet, processor, memory, and hard drive settings in real time for maximum system speed and performance.Some of the features include:
ARINC 818 (Avionics Digital Video Bus) is a point-to-point, 8b/10b-encoded (or 64B/66B for higher speeds) serial protocol for transmission of video, audio, and data. The protocol is packetized but is video-centric and very flexible, supporting an array of complex video functions including the multiplexing of multiple video streams on a single link or the transmission of a single stream over a ...
The network designer has to ensure the fault-free functionality in the design phase (one slave is allowed to send data to the bus in one frame time). If the identifier causes one physical LIN slave to send the response, the identifier may be called a Rx-identifier. If the master's slave task sends data to the bus, it may be called Tx-identifier.
Next to the free System Dynamics library, which is exclusively based on modeling signal flows, there is a free Business Simulation Library (BSL) dedicated to System Dynamics, which makes use of Modelica's acausal connectors to account for transitions of conserved matter.
