Word

Word 1

Bits 00Ć15 (00Ć17)

Output data for channel 0.

Word 2

Bits 00Ć15 (00Ć17)

Output data for channel 1.

Word 3

Bits 00Ć15 (00Ć17)

Minimum engineering scale factors for output channel 0 data.

Word 4

Bits 00Ć15 (00Ć17)

Maximum engineering scale factors for output channel 0 data.

Word 5

Bits 00Ć15 (00Ć17)

Minimum engineering scale factors for output channel 1 data.

Word 6

Bits 00Ć15 (00Ć17)

Maximum engineering scale factors for output channel 1 data.

Word 7

Bits 00Ć15 (00Ć17)

Minimum engineering scale factors for input channel 0 data.

Word 8

Bits 00Ć15 (00Ć17)

Maximum engineering scale factors for input channel 0 data.

Word 9

Bits 00Ć15 (00Ć17)

Minimum engineering scale factors for input channel 1 data.

Word 10

Bits 00Ć15 (00Ć17)

Maximum engineering scale factors for input channel 1 data.

Word 11

Bits 00Ć15 (00Ć17)

Minimum engineering scale factors for input channel 2 data.

Word 12

Bits 00Ć15 (00Ć17)

Maximum engineering scale factors for input channel 2 data.

Word 13

Bits 00Ć15 (00Ć17)

Minimum engineering scale factors for input channel 3 data.

Word 14

Bits 00Ć15 (00Ć17)

Maximum engineering scale factors for input channel 3 data.

Word 15

Bits 00Ć15 (00Ć17)

Low alarm level for input channel 0. When the input value for this channel is less than the low

value, the corresponding low alarm bit is set in the BTR.

Word 16

Bits 00Ć15 (00Ć17)

High alarm level for input channel 0. When the input value for this channel is greater than the

high value, the corresponding high alarm bit is set in the BTR.

Word 17

Bits 00Ć15 (00Ć17)

Alarm deadband for input channel 0. This field creates a hysteresis effect on the low and high

alarms. For an alarm condition to be removed, the input signal must go above the low alarm

limit or below the high alarm limit by an amount equal to the specified deadband. Alarm

deadband values must be less than or equal to one half the difference of the high and low

alarm values.

Word 18

Bits 00Ć15 (00Ć17)

Low alarm level for input channel 1. When the input value for this channel is less than the low

value, the corresponding low alarm bit is set in the BTR.

Word 19

Bits 00Ć15 (00Ć17)

High alarm level for input channel 1. When the input value for this channel is greater than the

high value, the corresponding high alarm bit is set in the BTR.

Word 20

Bits 00Ć15 (00Ć17)

Alarm deadband for input channel 1. This field creates a hysteresis effect on the low and high

alarms. For an alarm condition to be removed, the input signal must go above the low alarm

limit or below the high alarm limit by an amount equal to the specified deadband. Alarm

deadband values must be less than or equal to one half the difference of the high and low

alarm values.

Word 21

Bits 00Ć15 (00Ć17)

Low alarm level for input channel 2. When the input value for this channel is less than the low

value, the corresponding low alarm bit is set in the BTR.

Word 22

Bits 00Ć15 (00Ć17)

High alarm level for input channel 2. When the input value for this channel is greater than the

high value, the corresponding high alarm bit is set in the BTR.

Word 23

Bits 00Ć15 (00Ć17)

Alarm deadband for input channel 2. This field creates a hysteresis effect on the low and high

alarms. For an alarm condition to be removed, the input signal must go above the low alarm

limit or below the high alarm limit by an amount equal to the specified deadband. Alarm

deadband values must be less than or equal to one half the difference of the high and low

alarm values.

Word 24

Bits 00Ć15 (00Ć17)

Low alarm level for input channel 3. When the input value for this channel is less than the low

value, the corresponding low alarm bit is set in the BTR.
