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

Word 2
Bit 00
Multiplex control bits (M) for individual channel. This bit controls the safe state
analog outputs– Bit 00 corresponds to output channel 0.
1 = use words 0 (analog value) as directed by channel number n
0 = use words 6 (safe state analog value) as directed by channel number n
When bit 00 is cleared (0) simultaneously by a communication error or user choice
thru the programmable controller program, word 3 full range and configure select
bits are preserved at their last setting.
Bits 01-15 (01-17)
Not used – set to 0.
Word 3
Bits 00-01, 04
Full range bits (F) for individual channels – Bit 00 corresponds to input channel 0,
bit 01 corresponds to input channel 1, and bit 04 corresponds to output channel 1.
Refer to Range Bit Selections.
Bits 02, 03, 05-07
Not used – set to 0.
Bits 08-09, 12 (10,
11, 13-15)
Configure select bits (C) for individual channels – Bit 08 corresponds to input
channel 0, bit 09 (11) corresponds to input channel 1, bit 12 (14) corresponds to
output channel 0. Refer to Range Bit Selections.
Bits 14-15 (16-17)
Not used – set to 0.
