Description
Transmits the state of the input channel every time
there is a state change or if SCPTMaxSendTime in
the Node Object has expired.
Transmits the state of the input channel every time
there is a state change or if SCPTMaxSendTime in
the Node Object is expired. If configured as a
totalizer, this NV transmits the number of transitions
from 0 to 1.
Specifies the setting for a sensor channel.
Specifies the difference in totalizer count required
before a transmission of the value output of the
Sensor Object takes place.
Used to define the relation between the logical status
of the input and the state of the LED. One bit cor-
responds to one input channel (bit 4 = input channel
12, bit 15 (MSB) = input channel 1). If a bit is clear,
the LED for the channel will be 0=green and 1=red. If
the bit is set, then 0=red and 1=green.
