(Octal Bit)

Word

Word 1

Bits 00-14

(00-16)

Channel 1 analog data - 12Ćbit left justified two's complement number; unused

lower bits are zero; 4Ć20mA uses all 16 bits.

Word 1

Bits 15 (17)

Channel 1 analog data sign bit.

Word 2

Bits 00-14

(00-16)

Channel 2 analog data - 12Ćbit left justified two's complement number; unused

lower bits are zero; 4Ć20mA uses all 16 bits.

Word 2

Bits 15 (17)

Channel 2 analog data sign bit.

Word 3

Bits 00-14

(00-16)

Channel 3 analog data - 12Ćbit left justified two's complement number; unused

lower bits are zero; 4Ć20mA uses all 16 bits.

Word 3

Bits 15 (17)

Channel 3 analog data sign bit.

Word 4

Bits 00-03

Multiplex control bits (M) for individual channels. These bits control the safe

state analog outputs. - Bit 00 corresponds to output channel 0, bit 01

corresponds to output channel 1, and so on.

1 = use words 0, 1, 2 or 3 as directed by channel number n

0 = use words 10, 11, 12 or 13 as directed by channel number n

When bits 00Ć03 are all cleared (0) simultaneously by a communication error or

user choice thru the programmable controller program, word 5 full range and

configure select bits are preserved at their last setting.

Bits 04Ć15

(04Ć17)

Not used - set to 0.

Bits 00-03

Full range bits (F) for individual channels - Bit 00 corresponds to output channel

0, bit 01 corresponds to output channel 1, and so on.

Bits 04Ć07

Not used - set to 0.

Word 5

Bits 08-11

(10Ć13)

Configure select bits (C) for individual channels - Bit 08 corresponds to output

channel 0, bit 09 corresponds to output channel 1, and so on.

Bits 12Ć15

(14Ć17)

Not used - set to 0.

Words 6

thru 9

Bits 00-15

(00-17)

Not used - set to 0.

Word 10

Bits 00-14

(00-16)

Channel 0 Safe State analog value - 12Ćbit left justified two's complement

number; unused lower bits are zero; 4Ć20mA uses all 16 bits.

Word 10

Bits 15 (17)

Channel 0 Safe State analog data sign bit.

Word 11

Bits 00-14

(00-16)

Channel 1 Safe State analog value - 12Ćbit left justified two's complement

number; unused lower bits are zero; 4Ć20mA uses all 16 bits.

Word 11

Bits 15 (17)

Channel 1 Safe State analog data sign bit.

Word 12

Bits 00-14

(00-16)

Channel 2 Safe State analog value - 12Ćbit left justified two's complement

number; unused lower bits are zero; 4Ć20mA uses all 16 bits.

Word 12

Bits 15 (17)

Channel 2 Safe State analog data sign bit.

Word 13

Bits 00-14

(00-16)

Channel 3 Safe State analog value - 12Ćbit left justified two's complement

number; unused lower bits are zero; 4Ć20mA uses all 16 bits.

Word 13

Bits 15 (17)

Channel 3 Safe State analog data sign bit.
