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.
