Bits 00-14
(00-16)
Not used
Bits 13-14
(15-16)
Safe State Source bits (S1/S0) - Not used in ControlNet applications. Turn
these bits off (i.e. set to 0)
Bit 15 (17)
Output Enable bit (EN)
Set this bit off (0) for the output block
Set this bit on (1) for the configuration block
Word 3
Bits 00-15
(00-17)
Channel 0 output data. – The output data is real time data formatted to the
selected configuration. (This data is also safe state data when directed by S1
and S0.)
Word 4
Bits 00-15
(00-17)
Channel 1 output data. – The output data is real time data formatted to the
selected configuration. (This data is also safe state data when directed by S1
and S0.)
Word 5
Bits 00-15
(00-17)
Channel 2 output data. – The output data is real time data formatted to the
selected configuration. (This data is also safe state data when directed by S1
and S0.)
