Rev 1001

ADS2 Core Concepts


Rev 1001

ADS2 Characterization

ADS2 is a platform

◼ To host applications, e.g.

> Simulations

> Test applications

> Scripts

> Monitoring and control panels

> Complex visualizations

> I/O resources (by means of driver applications)

◼ To run all these types of applications in a well-defined,

deterministic, and reproducible way

◼ To exchange data between these applications in the form of

process variables, always guaranteeing consistency

Current Value Table (CVT)

◼ Storage for process variables

◼ Data atoms “CVT points”> Referred to by name with additional attributes

(min, max, type, unit, …)

> Scalar data types (numeric, string)

> Arrays (bus messages as byte arrays)

◼ Sampling and queueing access> Sampling: only newest value

> Queueing: value history

> Sampling outputs can be attached as queueing

inputs

◼ Publish / subscribe model

◼ Applications always read/write groups of

CVT points (consistency)

◼ System CVTs: part of system state

available via CVT points

◼ Control CVTs: allow behavior to be

manipulated

◼ CVT links: connection between PVs of

different name and type

◼ Combining multiple nodes into

a cluster

◼ Mix of real-time capable

nodes and display nodes

purposes

Partitioning and Virtualization

◼ Resource sharing / reuse

◼ Partition a single node into

multiple sub-nodes

> i.e. multiple ADS2

kernels on a single

computer

◼ Assign hardware resources

(I/O, CPUs) to sub-nodes

◼ Sub-nodes become part of

different clusters

◼ Through partitioning a cluster

configuration can be

developed without having a

real cluster

Runtime Dynamics

◼ On-the-fly reconfigurability

◼ So-called components pack multi-

platform binaries with their

scheduling attributes and the

necessary configuration items

(CVTs, I/O maps) into a bundle

◼ Components can also represent the

two forms of the same thing: the

simulated form and the actually

connected form

◼ Configuration from human readable

files

◼ Reconfiguration is not recompilation

◼ Drivers are ordinary applications,

(re-)startable at any time
