Write Word 4
Bits 00…03
Multiplex control bits – 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 00…03 are all cleared (0) simultaneously by
a communication error or user choice through the
programmable controller program, word 5 full range
and configure select bits are preserved at their last
setting.
Bits 04…15
(04…17)
Not used – set to 0.
Write word
6…9
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. See Range Selection Bits –
1794-OE4/B and 1794-OE4XT Analog Output Module on
page 52.
Bits 04…07
(04…09)
Not used – set to 0.
Bits 08…11
(10…13)
Configure select bits (C) for individual channels –
Bit 08 corresponds to output channel 0, bit 09
corresponds to output channel 1, and so on. See Range
Selection Bits – 1794-OE4/B and 1794-OE4XT Analog
Output Module on page 52.
Bits 12…15
(14…17)
Not used – set to 0.
