Represents the diagnostic results of every analog
output channel (00 to 0F for M-7024U and 00 to
FF for M-7028), where bit 0 corresponds to
channel 0, bit 1 corresponds to channel 1, etc.
When the bit is 1, it means that the channel is
either wire opening for current output or short
circuit for voltage output. If the bit is 0 it means
that the channel is normal.
