9.2.7 Sequence Flag
YES or NO
In order to save bandwidth, you can configure the Sequence Flag feature using
the following parameters:
If this parameter is set to NO, this feature is not selected, the module will send
the object address and value for every monitored point sent to the Client, and the
Sequence Flag (SQ) will be set to zero (0).
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.
