2.1 About vi
Error input and output are provided in each APS-1102 operation vi. Error cluster chains are
generated by connecting an error output to the error input of the next vi. This allows a natural error
I/O for the LabVIEW data flow architecture to be obtained. An application can monitor the
intermediate error status as required.
APS-1102 operation vi, except for Close, has a VISA session input and a duplicated VISA session
output. Use chain connections for these as well. Close has a VISA session input only, so the
application forms a chain from Initialize to Close.
Vi, of which input items contain Read, can output the contents set in the APS-1102. When
outputting, set the bool controller to ON (True). The default setting is OFF (False).
Parentheses ( ) at the end of an item name indicate default setting. For example, “Read (F)”
indicates that the default setting is “False”. In the same way, square brackets [ ] for numerical
controllers or the display device indicate quantity units.
See the sample application for actual connections.
The following sections describe error I/O, VISA session and I/O terminals except Read.
