Parameter Offset
This parameter specifies the Information Object Address (IOA) Offset to
normalized points parameter data. The value entered is added to the IOA for the
associated point to compute the parameter IOA address.
The Client may send a "Parameter of Measured Normalized" or "Parameter of
Measured Scaled" command using the parameter IOA in order to change the
threshold deadband values for specific points.
For example, if the 104S v2 configuration sets two M_ME_NA points with IOA
(Point #) of 600 and 601 and a M_ME_NA Parameter Offset value of 2000, the
threshold deadband parameters for those points would be written to IOA
addresses 2600 and 2601.
Note: The Low Limit and High Limit threshold values are always calculated based on the threshold
deadband value as described in the following table.
Point Value
Threshold Determined by the deadband set in the configuration file or altered by the write
command.
Low Limit Last reported event value - threshold.
High Limit Last reported event value + threshold.
