The Data Manager is also controls the Analog Inputs calibration process. This is a privileged operation and
allows an administrator to recalibrate the conversion factors and offsets on the various inputs and their associated
ranges. All units are shipped fully calibrated with a default set of calibration parameters stored in non-volatile
memory which may be recalled at any time.
The Data Storage Manager is used to set up the recording parameters required by the user. Recordings can be
started by the user or can be triggered to start as a result of an external event, an alarm condition or at a preset
time, once or on a daily basis. There is also a File Explorer. This is a privileged operation which enables an
administrator to rename, copy or delete files and move files between the various media.
The Alarm Event Manager is used to set up the various
alarms on the channels and route events to the
(optional) relay outputs. Various alarm types can be set. The operation of the (optional) relay contacts are also
defined here. This module processes data in real time checking it against the preset alarm conditions and reacting
accordingly as described above. There is a (soft)
master enable switch which allows the user to configure alarms
without affecting the actual (optional) relay contacts.
The Digital Input Manager is used to define the operation of the (optional) isolated
digital inputs and process
these inputs according to the user set conditions when they occur. Digital inputs can be used to reset timers or
totalizers, acknowledge and reset alarms, force events or start recording. There is a (soft) Master enable switch
which allows the user to configure the (optional) digital inputs without affecting the actual operation of the
recorder.
The Display & Keyboard Manager controls the content of the graphic display and interprets the input on the
display touch screen and passes this information to where it is required. The user can
create an infinite number of
visual screens using a combination of widgets – bar graphs, trends or digital displays. All the other modules
communicate with the Display Manager to provide status information to the user.
The System Manager controls the overall operation of the recorder and prioritizes events as required. It also
manages
system security and handles the administrative tasks such as importing or exporting configurations. It
services external requests (via the communication ports), controls the email and configures the unit at startup. It
also deals with any peripherals and routes the information accordingly.
