Read Word 5 Bit 00 Reserved.
Bit 01 Calibration Done bit (DN) – This bit is set to 1 after a calibration cycle is
completed.
Bit 02 Calibration Bad bit (BD) – This bit is set to 1 if the channel calibration coefficients
cannot be saved or be read properly.
Bits 03…07 Set to 0.
Bits 08…11
(10…12) Reserved.
Bit 12 (14) Set to 0.
Bit 13 (15) Configuration Mode bit (CF) – This bit is set (1) when the calibration mode is
selected (bit 15, word 5 in the block transfer write set to 1). When this bit is set (1),
the module status indicator flashes.
Bit 14 (16) Field Power Off bit (FP) – This bit is set (1) when the 24V field power fails. When
this bit is set (1), the module status indicator flashes.
Bit 15 (17) Power Up (unconfigured state) bit (PU) – This bit is set (1) when the configuration
word is all zeroes (0) due to a reset (adapter power cycle or module insertion) or a
cleared configuration word (all 0). When this bit is set (1), the module status indicator
flashes.
Read Word 6 Bits 00…03 Underrange bits (U) -These bits are set (1) when the input channel is below a preset
limit as defined by the configuration selected. U0 (bit 00) corresponds to input channel
0 and U1 (bit 01) corresponds to input channel 1, and so on. See
Configuring Your
Input Channel on page 45 .
Bits 04…07 Overrange bits (V) – These bits are set (1) when the input channel is above a preset
limit as defined by the configuration selected. Bit 04 corresponds to input channel 0
and bit 05 corresponds to input channel 1, and so on. See
Configuring Your Input
Channel on page 45 .

(00…16) Real Time Sample Interval – Programs the interval of the real time sample. Can be
varied from 0...30 s (3000 decimal). Resolution is in ms with granularity in 5 ms steps.
Bit 15 (17) Not used. Set to 0.
