hpe5250a_closeList_Q

This function will query the instrument for the channels closed given in the ’closechan_list’.

The parameter ’closechan_list’ is an array of integers with each integer representing one channel. The last number of the ’closechan_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 ’close_status’ parameter is an array of integers containing the return values of the query. The ’close_status’ array returned will correspond one to one with ’closechan_list’ parameter.

Syntax

ViStatus _VI_FUNC hpe5250a_closeList_Q(ViSession vi,

 

ViInt32_VI_FAR closechan_list[ ], ViInt32 _VI_FAR close_status[ ] );

Parameters

vi

Instrument handle returned from hpe5250a_init( ).

 

closechan_list[ ] Channel numbers to know the close 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.

 

close_status[ ]

Status of the channels given in the closechan_list.

 

 

0 (opened) or 1 (closed).

hpe5250a_cmd

This function passes the cmd_str string to the instrument. Must be a NULL terminated C string.

Syntax

ViStatus _VI_FUNC hpe5250a_cmd(ViSession vi, ViString cmd_str);

Parameters
