Type ID Type Description Data Representation
5 M_ST_NA_1
(7.3.1.5)
Monitored Step-point Information: This
data type is used for step position of
transformers or other step position
information. The value for the position
ranges from -64 to information for this
type are M_ST_TA_1 (6) and 63.
Associated time-tagged event
M_ST_TB_1 (32).
Step data (7.2.6.5) is stored in a single
character value with bits 0 to 6 (-64 to +63)
representing the step position and bit 7
representing the following states:
0 = Equipment is not in transient state
1 = Equipment in transient state
9 M_ME_NA_1
(7.3.1.9)
Monitored Normalized Measured Value:
This data type is used for analog input
data. Associated time-tagged event
information for this type are M_ME_NA_1
(10) and M_ME_TD_1 (34).
Normalized values (7.2.6.6) are stored in a (16-
bit) word data area with a range of -1..+1-2-15
11 M_ME_NB_1
(7.3.1.11)
Monitored Scaled Measured Value: This
data type is used for analog input data.
Associated time-tagged event information
for this type are M_ME_TB_1 (12) and
M_ME_TE_1 (35).
Scaled values (7.2.6.7) are stored in a (16-bit)
word data area with a range of -215.. +215-1
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)

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 -
231..+231-1.
45 C_SC_NA_1
