Legend:
Vn
Validity bit "valid" for channel number n = 0...3
NOTE:
set Vn = "1" for analogue
out
put slaves!
On
Bit "overflow" for channel number n = 0…3
OVA
Channel-independent bit "output data valid" of A slave
CTT1:
0 = more than 3.5 s have elapsed since the last update of the output values
1 = slave requests new output data within the next 3 s
CTT2…CTT5:
0 = slave receives no new output data
1 = slave receives new output data
TVA
Channel-independent bit "transmission valid" of A slave/single slave:
0 = error during transmission or: timeout
1 = transmission of analogue input/output data OK
OVB
Channel-independent bit "output data valid" of B slave:
CTT1:
0 = more than 3.5 s have elapsed since the last update of the output values
1 = slave requests new output data within the next 3 s
CTT2…CTT5:
0 = slave receives no new output data
1 = slave receives new output data
NOTE:
only valid for analogue
out
put slaves. Set OVB = 0 for
in
put slaves!
TVB
Channel-independent bit "transmission valid" of B slave:
0 = error during transmission or: Timeout
1 = transmission of analogue input/output data OK
TIA
Slave transmits analogue input data...
0 = in the analogue mode (15 bits, with sign)
1 = in the transparent mode (16 bits, without sign)

TOA
slave receives analogue output data...
0 = in the analogue mode (15 bits, with sign)
