sensor) and 20mA representing the highest reading (e.g. 10 bar on a 0-10 bar pressure sensor). This is a function of the
sensing device.
The interface on the logger needs to be told what the parameters are for the type of sensor attached, as well as, what that
sensor is measuring. This is done through the Loop Low Value, Loop High Value and Loop Units parameters. The Loop Low
Value would be the lowest reading for that sensor (i.e. 4mA reading), the Loop High Value, the highest reading (i.e. 20mA
reading) and the Loop Units, the unit of measure.
An example of a submersible 4-20mA level pressure sensor that reads up to 10 metres.
Loop Low Value = 0
Loop High Value = 10
Loop Units = metres
Next are the 'General Setup' parameters. These are parameters that are used for the general descriptions and applications
of the logger.
Very important here is the 'Vendor Code'. The Cloudworks System supports multiple databases. What this means is that the
server will automatically populate the database that is associated with a specific logger. Each database and logger has a
Vendor Code assigned to it. Data is matched between these systems using that code. This code is also used to separate
communications between different vendors, preventing the cross accessing of loggers by unauthorised users. The Vendor
Code is assigned to the relevant subsystem by the administrator during the creation of the database on the server.
The description is a simple string of data that is stored by the logger and used to identify that logger in simple terms. Here,
it is best to use wording that might explain something about where this logger has been applied.
Application types are explained in detail earlier in this document. To select an application type, simply click the dropdown
arrow on the right of the entry field and select the application type you wish to apply.
Since this logger has no onboard GPS, co-ordinates are recorded in the latitude and longitude fields which will be sent
through to the database during a reload device configuration event.
