The thresholds can be freely defined by the user. The user can
also preset the logical signal level (see also the configuration
software COMBILOG.EXE).
Thus it is possible to activate a digital output depending on a
specified time or periodically. This can be realized in connec-
tion with an arithmetic channel, that can calculate the time or a
time interval from the internal real time clock. A typical applica-
tion is to switch off a modem after a specified time to reduce
the power consumption of battery powered systems.
