hpe5250a_openList_Q

This function will query the instrument for the channels open given in the ’openchan_list’.

The parameter ’openchan_list’ is an array of integers with each integer representing one channel. The last number of the ’openchan_list’ should be "0" (numeric zero) to identify the end of the list. The maximum number of channels that can be specified by the list is 100.

The ’open_status’ parameter is an array of integers containing the return values of the query. The ’open_status’ array returned will correspond one to one with ’openchan_list’ parameter.

Syntax

ViStatus _VI_FUNC hpe5250a_openList_Q(ViSession vi,

 

ViInt32_VI_FAR openchan_list[ ], ViInt32 _VI_FAR open_status[ ] );

Parameters

vi

Instrument handle returned from hpe5250a_init( ).

 

openchan_list[ ] Channel numbers to know the open status. 5 digits integer.

 

 

ABCDE. where A: card number, BC: input port number, DE:

 

 

output port number. Top zero(s) can be ignored. For example, if

 

 

A=0, BC=01, and DE=01, channel number should be 101

 

 

instead of 00101.

 

open_status[ ]

Syntax

ViStatus _VI_FUNC hpe5250a_readStatusByte_Q(ViSession vi,

 

ViPInt16 statusByte);

Parameters

vi
