Definition

Input Word 0

Bits 00-14

(00-16)

Channel 0 analog data – 12-bit left justified two’s complement number;
unused lower bits are zero; 4-20mA uses all 16 bits.

Bits 15 (17)

Channel 0 analog data sign bit.

Word 1

Bits 00-14

(00-16)

Channel 1 analog data – 12-bit left justified two’s complement number;
unused lower bits are zero; 4-20mA uses all 16 bits.

Bits 15 (17)

Channel 1 analog data sign bit.

Word 2

Bits 00-14

(00-16)

Channel 2 analog data – 12-bit left justified two’s complement number;
unused lower bits are zero; 4-20mA uses all 16 bits.

Bits 15 (17)

Channel 2 analog data sign bit.

Word 3

Bits 00-14

(00-16)

Channel 3 analog data – 12-bit left justified two’s complement number;
unused lower bits are zero; 4-20mA uses all 16 bits.

Bits 15 (17)

Channel 3 analog data sign bit.

Word 8

Bits 00-03

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,
and so on. When set (1), indicates either a broken or open input wire, or input
current at or below 4mA.

Bits 04-14

(04-16)

Not used – set to 0.

Bit 15 (17)

Power Up bit .- This bit is set to 1 when all bits in the configuration
register (write word 0) are 0 (unconfigured state).
The configuration
register can be cleared by either a reset, or by the user writing all zeroes to it.
