Q1
Monitoring module:
The
Monitoring
module facilitates the compilation of process value archives
(archives with any measurements or count values). Moreover, it runs the gas
quality measurement’s error logbook. The beginning and ending of all error
types (alarm, warning, hint
– see Chapter 5.3.1) are entered in the listing in clear
text and together with a time mark. There is an additional, separate error listing
for internal message processing, if this function is used. This error listing can
also be logged.
System
module:
The
System
module runs a parameter change archive (
changed settings
archive
)
)
, in which changes of the parameterisation are logged.
If individual parameters are modified, the old and new values will be logged in
addition to the time mark. The module to which the changed parameter belongs
is also displayed.
A completely new parameterisation will be entered in the changed settings
archive as
New parameterisation
via the data interface when the calibration
switch is open. A change of the parameterisation’s operational part is marked as
New operational parameterisation
.
Note:
The archive depth, exact composition and order of archives can be
configured by the user via the parameterisation. However, when changing the
archive structure, you have to delete the old archives already existing in the
device.
The devices have already been provided with a pre-defined archive structure
corresponding to the common requirements before delivery.
