Legend:
Vn
valid bit
1 bit
0 = values in channel n are invalid
1 = values in channel n are valid
Output data must be valid (Vn = 1) to be enabled in the AS-i slave!
On
overflow bit
1 bit
0 = data is in the valid range
1 = data is in the invalid range (especially in case of input modules when
the measuring range is not reached or exceeded)
OVx
output valid
1 bit
channel-independent bit "output data valid" from the 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.
For
in
put slaves set OVx = "0"!
