Full Description
Scope
This standard describes a serial control bus for interdevice/intrabuilding interconnection of microcontrollers. Intrasite interconnection is also provided.This standard, which focuses on OS1 layers 1,2, and 7, may be used with other standardsand practices to effect total solutions to specific applications.Purpose
This standard defines an interconnect bus for (but not limitedto) microcontrollers and devices with limited reprogrammability. This bus provides amulti-drop bit-serial communication protocol that will allow the interconnection of distributed,independently manufactured devices. The protocol is optimized for instrumentation,distributed data acquisition systems, control devices, and test and measurement.The purpose of Section 1 is to serve as the foundation for the standard. It contains theoverall definition of the bus network as well as a reference model for protocol sections.Protocol descriptions are contained in later sections of this document. This section containsthe basis for those descriptions, such as the primitives employed to describe interactionsbetween layers in the protocol reference model. An important part of this section is adescription of what is meant by conformance to IEEE Std 1118-1990This standard defines an interconnect bus for (but not limitedto) microcontrollers and devices with limited reprogrammability.

New IEEE Standard - Withdrawn.A serial control bus for interdevicehtrabuilding as well as intrasite interconnection of microcontrollers is described. The bus, which is defined for (but not limited to) microcontrollers and devices with limited reprogrammability, provides a multidrop bit-serial communication protocol that will allow the interconnection of distributed Independently manufactured devices. The protocol is optimized for instrumentation, distributed data acquisition systems, control devices, and test and measurement. Specifications for a common architecture, generic bus services, system wagement, data link, and several physical media are provided.The serial control bus expands upon BITBUS without making existing devices obsolete. System reliability has been enhanced by the addition of a system management layer, and generic bus services have been expanded.
