vi = contains a session handle to the instrument. This handle is obtained by the function and remains valid until the
session is closed.
set0_lower[] = a return array of Boolean values representing the accumulated limit status of all 48 channels with
respect to each channel’s limit set 0 lower limit. Channel 0 through channel 47 are represented in array elements [0]
through [47], respectively. If a “1” is returned, the set 0 lower limit has been tripped. If a “0” is returned, the set 0
lower limit has not been tripped.
set0_upper[] = a return array of Boolean values representing the accumulated limit status of all 48 channels with
respect to each channel’s limit set 0 upper limit. Channel 0 through channel 47 are represented in array elements [0]
through [47], respectively. If a “1” is returned, the set 0 upper limit has been tripped. If a “0” is returned, the set 0
upper limit has not been tripped.
set1_lower[] = a return array of Boolean values representing the accumulated limit status of all 48 channels with
respect to each channel’s limit set 1 lower limit. Channel 0 through channel 47 are represented in array elements [0]
through [47], respectively. If a “1” is returned, the set 1 lower limit has been tripped. If a “0” is returned, the set 1
lower limit has not been tripped.
set1_upper[] = a return array of Boolean values representing the accumulated limit status of all 48 channels with
respect to each channel’s limit set 1 upper limit. Channel 0 through channel 47 are represented in array elements [0]
through [47], respectively. If a “1” is returned, the set 1 upper limit has been tripped. If a “0” is returned, the set 1
upper limit has not been tripped.

ESCRIPTION
This function returns the accumulated limit status of all 48 channels. Limit status is returned for all channels,
regardless of their inclusion in the scan list. The returned values represent, on a per channel basis, any excursion of
the measurement data over their respective limits since the last trigger initialize. As implied, limit status is cleared as
part of the vtex10xxA_init_imm function.
The limit status for unscanned channels is always 0.
