Bits 00-01
Underrange bits (U) for individual channels (4-20mA current input only)-
Bit 00 corresponds to input channel 0, bit 01 corresponds to input channel 1.
When set (1), indicates either a broken or open input wire, or input current at
or below 4mA.
Bits 02-03 Reserved
Bits 04
Wire Off bits (W) – Current outputs only – When set (1), the wire on the
current output is broken or the load resistance is too high. Bit 00 corresponds
to channel 0.
Bits 05-14
(05-16)
Reserved
Bit 15 (17)
Power Up bit - This bit is set to 1 when all bits in the configuration
register (write word 3) are 0 (unconfigured state). The configuration
register can be cleared by either a reset, or by the user writing all zeroes to it.
