ADS2 Core Concepts


Rev 1000

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

I/O Mapping

Isolating and decoupling applications from direct access to I/O

Mapping of process variables to I/O channels (i.e. I/O hardware)

Channels denote all types of I/O handled by the I/O subsystem

> Busses > Discretes > Analog > Ethernet-attached measurement

devices EU conversion (e.g. scaling) Composition and

decomposition of messages

Clustering & Time Synchronization

Pooling of > Computing resources > I/O resources > Logical functions (e.g. FIBs)

Combining multiple nodes into a cluster

Mix of real-time capable nodes and display nodes

Mix of soft and hard time-synchronized nodes

I/O typically distributed over multiple nodes

Each node can act as a master in the cluster for (re)configuration and control 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
