If this parameter is set to YES, this feature is selected, the module will send the
object point address and value for only the first point of a sequence of points,
send only the data value without point address for any remaining points in the
sequence, and the Sequence Flag (SQ) will be set to one (1). When SQ = 1, the
Client assumes that all points after the first point use Information Object
Addresses in a contiguous order (using the first point as the reference starting
address).
Note: Refer to the Client device specification to verify if this feature is supported before you
consider using it.
5.7.7 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 PTQ-104S configuration sets two M_ME_NA points with IOA
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.
