Terminology Flashcards
is an abnormal state of a condition associated with an Aspect Object. For example, the object FC101 may have the following conditions associated with it:
HighAlarm, HighHighAlarm, Normal, LowAlarm, and LowLowAlarm.
An alarm is active as long as the abnormal state of the corresponding condition persists. An alarm is unacknowledged until a user has acknowledged it.
Alarm
Server that runs system applications, such as the Information Management History Services, Production Management (Batch Management and Production Management), Asset Optimization, Process Optimization, Simulation, and also third party and user provided applications
Application Server
A representation of a facet of a real world entity, which entity is represented as an Aspect Object. An aspect defines a piece of information, and a set of functions to create, access, and manipulate the information.
Aspect
Platform functionality that supports integration of aspect systems and connectivity components, including concepts, APIs, and tools.
Aspect Framework (Afw)
are representations of real world entities that a user interacts with, such as valves, reactors, products, material, production orders, batch procedures, customer accounts, etc.
Different facets of these real world entities are modeled as aspects. An Aspect Object is not an object in a strict sense, e.g. like a COM object, but rather a container of references to implementations of its aspects.
Aspect Object
A server that runs the central functions of the Aspect Object architecture, such as Aspect Directory, Structure and Name Server, Cross Referencing, File Set Distribution, etc.
Aspect Server
The process by which the system validates the user’s logon information. A user’s name and password are compared against an authorized list. If the system detects a match, access is granted to the extent specified in the permissions list for that user.
Authentication
CEX bus
Communication Expansion Bus
is used for communication between servers, and between workplaces and servers.
Client/Server network
A server that provides access to controllers and other sources for real-time data, historical data, and alarm and event data. A Connectivity Server runs services related to OPC/DA, APC/AE, OPC/HDA, and SysMsg
Connectivity Server
The programming tool for AC800M. Often referred to as Control Builder or CBM. Control Builder M Professional is integrated into the System 800xA.
Control Builder M (CBM)
is a local area network (LAN) that is optimized for high performance and reliable communication with predictable response times in real time. Control network devices and servers are connected to the control network.
Control network
is used to interconnect field devices, such as I/O modules, smart sensors and actuators, variable speed drives, PLCs, or small single loop devices, and to connect these devices to the 800xA system.
Fieldbus
A computer communicating on a network e.g. the Internet, Plant, Control or I/O network. Each node typically has a unique node address.
Node
OLE (Object Linking and Embedding) for Process Control, a standard interface for data, event and history access based on COM.
