What is CLUSTER ERROR IN AND ERROR OUT?

vanny · ‎01-15-2010

See the picture:

I don't understand what is error in and error out?

I have read the text, but I ask: when ths error in start? All Icon have a error IN, but where is the first possibility of error?

If I have understood very weel I MUST CONNECT ERROR OUT OF EACH BLOCK WITH ERROR OUT OF NEXT so i can have a controll of error in my process?

It's ok?

Thanks,
Vanny

You should connect error out of any block to error in of following block.

In order to manage errors, you should verify if an error has happened on application-critical points, then decide how to proceed according to your needs...

Nevertheless, you should start with basics of error handling

The error-in/error-out wires serve two main purposes:

1) It helps control data flow. In text based languages, flow (in general) is top to bottom.
In LabVIEW, it is directed by wires, so you can pass consective functions with their error clusters.

2) The error clusters allow the programmer to do error handling however they would like,

as well as establish what error specifically is causing the problem.
