GuardII+ Operation

• The monitor can read ambient temperature and humidity surrounding the asset with
the addition of an optional ambient sensor.
• The monitor can read data from analog signals with the addition of an optional Remote
I/O Unit.

4.4. Measurement Results

GuardII+ measurement results include the following types of information, which can vary
depending on the monitoring technology:

• Raw measurement data – this is the measurement data that provides the basis for the
analysis results.

• Summary data – this is the post-analysis measurement data.
• Operating Conditions – this is the Operating Condition data associated with that
measurement (only available for Operating Conditions that are configured).
• Measurement status and/or quality – this indicates the overall status of each
measurement. For example, the results may indicate that the measurement did not
complete successfully.

• Measurement Alert status – this indicates if the measurement caused an Alert
condition.

Measurement results can be obtained in two ways.

4.4.1. GuardII+ Archive
While GuardII+ is running, it collects data and automatically stores it in internal memory;
this is referred to as the Archive. The Archive can be downloaded into IAM and analyzed
later.
The Archive works differently for each installed monitoring technology.
NOTE:
Periodically, the Archive should be downloaded into IAM and the data
reviewed. This allows for early detection of any asset problems indicated
by the measurement results, as well as detection of any GuardII+ problem
should it occur. The recommended data download and review interval is
no more than six months.

4.4.2. Modbus Outputs

Measurement data is hosted inside the monitor for an external Modbus master to read.
To access the data registers, connect to the GuardII+ using Ethernet and query the monitor
using the standard Modbus over TCP/IP protocol. This data is updated after every
measurement cycle.
• Modbus data outputs vary for each monitoring technology, but typically include
measurement time, status and summary numbers for each input for each technology.
• Modbus data outputs do not include any raw data.
