Why LabVIEW? Post Mortem analysis of transient events is much easier with LV than with Java.

Equipment experts are using LV to debug and commission their systems

PXI with LV-RT will be used for fast digitisers (8 GS/s), HW and drivers not available in VME.

On-line beam diagnostics needs fast software development tool to enable expert operators to quickly understand instabilities, resonances, beam losses, …

LabVIEW - CMW wrapper Get and Set functions are implemented.

Every Get command has 5 different modes:

0 – synchronous

1 – first request is synchronous and all next is asynchronous

2 – asynchronous

3 – subscribe property

4 – unsubscribe property

5 – last value from cache.

Data exchange Java-LabVIEW

The problem: OASIS - observation of analog signals system,

difficult to modify. Need for fast programmable signal analysis application

(FFT, filters, convolution, correlation,…).

Our solution: Connect via NI library to send data to the DataSocket

server. Then connect from any LabVIEW application to the

DataSocket server to receive the data. Minimum investment: only a Java data interface.

MAIntegration of LV-RT and PXI LV-RT on PXI can publish data.

Using LV8: network variables.

LV control room application merges OASIS and LV-RT data.

Questions Can we profit from CS? If yes, how? Should we try DIM? Try LV8?
