help - Net-Control Alarms 28.03.94
≤Net-Control alarms:≥
Net-Control gives three possibilities for reacting to
invalid values. For each parameter, to which you can
assign minimum and maximum limiting values, you can choose
between the following possibilities:
⌠No alarm⌡:
Even if no alarm is selected, the values are controlled.
Is the value too high, it is marked red and if it is
to low it is marked green on the screen for controlling
the actual data.
⌠Simple alarm⌡:
Net-Control gives an additional acoustic alarm tone and
writes one corresponding message with time, reason of
the alarm, limit and actual value to the logfile.
⌠Alarm with copy of the hitlists⌡:
The hitlists give a more precise description of the
situation than the stored data. Therefore, in case of
an alarm, these hitlists can be of interest. Usually
these are not stored for a longer time. By choosing this
alarm all actual hitlists are copied and saved with the
alarm message.
≤Assigning values to alarms:≥
Additionally you can assign to every alarm a value
between 1 and 255. This value can be edited in decimal
or binary. The default value ⌠0⌡ means, that this alarm
has ≤no≥ value assigned to it.
≤This value can be used in two ways:≥
You can assign these numbers according to the
importance of the alarms: (value 1 - unimportant
to value 255 - critical alarm). Net-Control writes the
assigned values in the corresponding alarm messages
behind a ⌠°⌡ character.
On the other hand this value is outputted to the
parallel port, if you have choosen the alarm port LPT1
or LPT2 in the configuration menu. By additional
hardware (for example a 8 channel centronics relais-
interface) you have the possibility of special
processing these alarms.
