5.3 Digital Output Channel
5.3.1 Digital Status Output
The digital output channel supports:
 digital status output, host-controlled
 digital status output, process-controlled
Via the digital inputs/outputs I/O 1 to I/O 6 on the data logger
COMBILOG 1022 digital status can be output in digital form,
according to the configuration. A typical case of application
would be e.g. the local output of an acoustic or optical signal in
case a limiting value is exceeded or undershot by a measured
value.
All outputs are open-collector.
The supply voltage can range from 10 up to 30 VDC. It has to
be either supplied externally or taken from the power supply of
the data logger.
The status of the digital output can be scanned as 1/0 informa-
tion via bus.
With the host-controlled digital status output, the digital output
is set according to the status information received by the data
logger via bus.
With the process-controlled output of status information the
data logger monitors measured values, resp. sensor channels
from excess of default threshold values. The digital output is
set if one or several threshold conditions are fulfilled.
