Which tags should be integrated?

The tags available via Modbus or DN3 are listed in the profile documents, available from the MultiTrode
website – www.multitrode.com.
The points list is extensive.
Also, note that additional tags can easily be added to the points list. See the notes in sections 5.4 and
5.5).
Because of the pre-configured nature of the product there are a large number of tags available for
integration. There will often be many tags not used in a specific MultiSmart installation.

5.1 Examples of tags or points not used in an installation

The profile document includes DNP3 points (and Modbus points) for:
•
"Pump 1 Seal fault" – this fault will only exist when a pump seal sensor is wired into MultiSmart
and configured
•
"Well 1 Backup level invalid" – this fault only occurs when a backup level device is configured
•
"Well 2 Level" – this fault only occurs in 2 well applications
Therefore, there can be a large number of tags which will not be configured in any one installation.

5.2 Active Faults and Unacknowledged Faults

MultiSmart faults often have 3 states – active; unacknowledged and cleared
•
Active is the typical fault state where the fault condition is present
•
Unacknowledged is a very useful fault condition, indicating that the fault has occurred, the
source of the fault has cleared, but the indication remains for operations that the fault was
present
Therefore, 2 tags are often used for one fault, e.g. Under-voltage has 2 tags:
•
Faults.Station.UnderVoltage.Status.Active
•
Faults.Station.UnderVoltage.Status.Unacknowledged
The integration can include both tags, or simply the active tag.
Resetting the fault is now available when the fault is in the unacknowledged state. A number of fault
reset tags exist to allow pump and station faults to be cleared. Some of these can be seen in the
Intermediate 2-pump application (section 5.5).

5.3 Integration approach

We give 2 examples to make integration of a MultiSmart pump station as easy as possible. These are
indicative only, to assist integrators new to the product.
To see an example of a more extensive implementation, with a few hundred tags per site, review the
Outpost2 functional specification, available on www.multitrode.com
The definitive tag list is always the DNP3 and Modbus Slave profiles, available on the MultiTrode website.
