agb220xa_groundChanList_Q

This function will query the instrument for the status, ground enabled or disabled,

for the channels given in the list.

The parameter “gndchan_list” is an array of integers with each integer representing

one channel. The last number of the “gndchan_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 “gnd_status” parameter is an array of integers containing the return values of

the query. The “gnd_status” array returned will correspond one to one with

“gndchan_list” parameter.

Syntax ViStatus _VI_FUNC agb220xa_groundChanList_Q(ViSession vi,

ViInt16 gnd_disen, ViInt32_VI_FAR gndchan_list[ ],

ViInt32_VI_FAR gnd_status[ ] );

Parameters vi Instrument handle returned from agb220xa_init( ).

gnd_disen Query type.

0 : checks if the port is the ground enabled.

1 : checks if the port is the ground disabled.

gndchan_list[ ] Channel numbers to check the 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.

gnd_status[ ] Status of the channels given in the gndchan_list. Returned value

depends on the setting of gnd_disen as shown below:

when gnd_disen=0, 0 means ground disabled, 1 means enabled.

when gnd_disen=1, 0 means ground enabled, 1 means disabled.
