Points List Regeneration for DNP3 and Modbus Slaves
or
CAUTION: Do not perform a points list regeneration unless you fully understand the options and
are aware of the implications.
Very occasionally it may be necessary to regenerate a DNP3 or Modbus slave points list. For example, a
newer version of the MultiSmart firmware may contain new points which are required in an existing
installation. The firmware would be upgraded first and then based on the type of the points list already in
use, one of the options described below selected. If the points list has been customised, these customised
points will be lost and must be re-entered.
In the case of Fixed points list, the new points are located in reserved locations. For a Dynamic points list,
the new points are located throughout the list. A firmware upgrade does not add these new points into the
existing points list - the existing points list is preserved. This is done in case the points list has been
customised.
Three different operations can be performed on the points lists.
(a) Fixed List – This generates a Fixed points list. The points list contains 'gaps' or reserved points in
amongst the valid points. These reserve points have no immediate function except to reserve a location
for a potential future point. (This allows for the addition of new points to be grouped with points of similar
functionality rather than simply attached to the end of the list).
A MultiSmart leaves the factory with a Fixed points list.
(b) Dynamic List – This generates a Dynamic points list. All points in the list are contiguous – there are no
'gaps' or reserved points.
(c) Clear List – Clears the entire points list, i.e. the points list contains no points.
CAUTION: Performing any of the above options on an existing pump station overwrites the existing
points list so any customised points will be lost and must be re-entered.
However, the points regeneration for the slaves configured under the Modbus master has a different set of
choices as follows.
(a) Clear List – Clears the entire points list, i.e. the points list contains no points.
(b) ADAM-6017 – Generates the points list for the ADAM 6017 external IO unit.
(c) ADAM-6050 – Generates the points list for the ADAM 6050 external IO unit.
(d) ADAM-6051 – Generates the points list for the ADAM 6051 external IO unit.
(e) Acromag 961EN-4006 – Generates the points list for the Acromag 961EN-4006 external IO unit.
(f) Acromag 983EN-4012 – Generates the points list for the Acromag 983EN-4012 external IO unit.
The MultiSmart has support for remote reconfiguration of DNP points list via DNP file transfer from the
master station. Contact MultiTrode to find out more details about how to configure the DNP master station to
support this.
