Word 5
Bits 00-03
Wire-Off status bits. (W). – These bits, when set (1), indicate the
corresponding current output channel is open. W0 corresponds to channel 0,
W1 corresponds to channel 2, etc.
Bits 04-07
Set to 0.
Bits 10-11
(12-13)
Hold output bits (P). – These bits are set (1) in response to Q0 or Q1 and a
transition of the EN bit. When P0 or P1 is set (1), they indicate that the output
is holding at the level in the readback data for the respective channel. These
bits return to 0 when the output data matches the readback output data.
Bits 12-15
(14-17)
Set to 0.
Output Word 0
Bits 00-12
(00-14)
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 configuration block.
Set this bit on (1) for the output block.
Word 1
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 S!
and S0.)
Word 2
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 3
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.)
Word 4
Bits 00-15
(00-17)
Channel 3 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.)
