Section 2 - Overview
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
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.
