These points would be used as follows:
Inf. Object Address Module Database Address
100 Bit 0 of word 100
101 Bit 1 of word 100
102 Bit 2 of word 100
The monitored double-point uses two bits with bit-addressing. It typically
represents the ON/OFF states where:
01 = OFF
10 = ON
M_ST_NA
The monitored step-point uses one byte with byte-addressing.
For example, if you configured the following points:
# Point # DB Address Group(s) IV DB Bit
# ------- ---------- -------- -------------
START
300 40 80000000 0
301 60 00000200 0
302 81 00000400 0
END
These points would be used as follows:
Inf. Object Address Module Database Address
300 Low Byte of word 20
301 Low Byte of word 30
302 High Byte of word 40
M_ME_NA and M_ME_NB
The monitored measured normalized and measured scaled points occupy one
word with word-addressing.
For example, if you configured the following points:
# Default
# Point # DB Address Group(s) Deadband IV DB Bit
# ------- ---------- -------- -------- ---------
START
400 10 80000000 0 0
401 12 00000200 0 0
402 18 00000400 0 0
END
These points would be used as follows:
Inf. Object Address MVI69-101S Module Database Address
400 Word 10
401 Word 12
402 Word 18
The monitored measured normalized points use a data representation defined by
the protocol specification, where each bit represents a value as follows:
