The Power Management Bus (PMBus) is a variant of the System Management Bus (SMBus) which is targeted at digital management of power supplies.Like SMBus, it is a relatively slow speed two wire communications protocol based on I²C.
Using a standardized interface and protocol allows systems-management software based on IPMI to manage multiple, disparate servers. As a message-based, hardware-level interface specification, IPMI operates independently of the operating system (OS) to allow administrators to manage a system remotely in the absence of an operating system or of the system management software.
There is no limit in the I²C-bus protocol as to how long this delay can be, whereas for an SMBus system, it would be limited to 35 ms. The SMBus protocol just assumes that if something takes too long, then it means that there is a problem on the bus and that all devices must reset in order to clear this mode.
To prevent preemption of its technologies by aggressive patenting, the Wishbone specification includes examples of prior art, to prove its concepts are in the public domain. A device does not conform to the Wishbone specification unless it includes a data sheet that describes what it does, bus width, utilization, etc. Promoting reuse of a ...
In computer engineering and electrical engineering, bit banging [1] or bit bashing [citation needed] is a term of art for any method of data transmission that employs software as a substitute for dedicated hardware to generate transmitted signals or process received signals.
UPB - 2-way Peer to Peer Protocol; VSCP - Very Simple Control Protocol is a free protocol with main focus on building- or home-automation; xAP – Open protocol; X10 – Open standard for communication among electronic devices used for home automation (domotics) Z-Wave - Wireless RF Protocol; Zigbee – Open protocol for Mesh Networks
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.
