Type ID Type Description Data representation
13 M_ME_NC_1
(7.3.1.13)
Monitored Measured Value, Short Floating-
Point Number: This data type is used for
analog input data stored in floating point
format according to the IEEE STD 754, QDS
format. Associated time-tagged event
information for this type are M_ME_TC_1
(14) and M_ME_TE_1 (36). Short floating-point number stored in
IEEE STD 754 format (Fraction,
Exponent, Sign) (7.2.6.8)
15 M_IT_NA_1
(7.3.1.15)
Monitored Integrated Total-point Information -
-This data type stores meter or other count
data. Associated time-tagged event
information for this type are M_IT_TA_1
(15)and M_IT_TB_1 (37). Binary counter data (7.2.6.9) is stored in
a double-word (32-bit) value with a
range of -2
31 ..+2 31 -1.
45 C_SC_NA_1
(7.3.2.1)
Single-point Command: This command
controls a single binary point such as a relay. Single bit value (7.2.6.15) with 0 = Off
and 1 = On
46 C_DC_NA_1
(7.3.2.2)
Double-point Command: This command
controls a dual-point binary control device
such as a trip/close relay. Double Command (7.2.6.16) with 0 =
Not permitted 1 = Off 2 = On 3 = Not
permitted
47 C_RC_NA_1
(7.3.2.3)
Regulating Step Command: This command
controls a stepping device such as a
transformer. Regulating Step Command (7.2.6.17)
with 0 = Not permitted 1 = Next step
lower 2 = Next step higher 3 = Not
permitted
48 C_SE_NA_1
(7.3.2.4)
Setpoint Command, Normalized Value: This
command controls an analog device. Normalized values (7.2.6.6) are stored in
a word (16-bit)data area with a range of -
1..+1-2
-15
49 C_SE_NB_1
(7.3.2.5)
Setpoint Command, Scaled Value: This
command controls an analog device. Scaled values (7.2.6.7) are stored in a
word (16-bit) data area with a range of -
2
15 .. +2 15 -1
50 C_SE_NC_1
(7.3.2.6)
Setpoint Command, Short Floating-Point
Format: This command controls an analog
device accepting an IEEE STD 754 floating-
point format value. Short floating-point number stored in
IEEE STD 754 format (Fraction,
Exponent, Sign) (7.2.6.8)
51 C_BO_NA_1
(7.3.2.7)
Setpoint Command, 32-bit Bitstring: This
command controls a bitstring in a device. Each of the 32 bits in the bitstring has a
value of 0 or 1 (7.2.6.13).
The data addressing is resumed in the following table:
