Data Tables 65
Write word 4 Bits 00…14
(00…16) Channel 3 analog data – 12-bit left justified two's
complement number; unused lower bits are zero;
4…20 mA uses all 16 bits.
Bit 15 (17) Channel 3 analog data sign bit.
Write word 5 Bits 00…11
(00…13) Configuration – Set the 2 bit pattern that configures
a pair of channels for Off, 0…20 mA, 4…20 mA, and
±10V. For more information, see Table Range

.
Bits 12…14
(14…16) Set to 0.
Bit 15 (17) Quick Step bit – Set to 1 to allow input filter to be
reduced during rapid signal changes. Ince the signal
change is within 1% of FS (that is, 327 counts),
filtering is returned to normal.
