M_ME_NB point count : 10 #Number of monitored scaled-points
This parameter specifies the number of point values assigned in monitored
scaled-point database. Range is 0 to 1000.
M_ME_NC point count : 10 #Number of monitored scaled-points
This parameter specifies the number of point values assigned in monitored
scaled short-float point database. Range is 0 to 50.

This parameter specifies the number of point values assigned in monitored
counter-point database. Range is 0 to 99.

2.4.4 Sequence
Flag
M_SP_Na Sequence : Yes #Y=ASDU in sequence with SQ=1, N=report separate (SQ=0)
M_DP_Na Sequence : Yes #Y=ASDU in sequence with SQ=1, N=report separate (SQ=0)
M_ME_Na Sequence : Yes #Y=ASDU in sequence with SQ=1, N=report separate (SQ=0)
M_ME_NB Sequence : Yes #Y=ASDU in sequence with SQ=1, N=report separate (SQ=0)
M_ME_NC Sequence : Yes #Y=ASDU in sequence with SQ=1, N=report separate (SQ=0)
M_IT_Na Sequence : Yes #Y=ASDU in sequence with SQ=1, N=report separate (SQ=0)
In order to save bandwidth, you can configure the module to use the Sequence
Flag feature. If this feature is not selected, the module will send the object
address and its value at every monitored response to the master.
If this parameter is selected, the module will turn the Sequence Flag on every
monitored response sending the address for the first point along with all point
values. The master assumes that all other points use information object
addresses in a contiguous order (using the first point as the reference).
