206 Practical Modern SCADA Protocols: DNP3, 60870.5 and Related Systems For example, M_ME_TA_1 is monitored information, a measured value, with time tag, and type A, which is a normalized value with quality. Type No. Description Reference not defined single-point information M_SP_NA_1 single-point information with time tag M_SP_TA_1 double-point information M_DP_NA_1 double-point information with time tag M_DP_TA_1 step position information M_ST_NA_1 step position information with time tag M_ST_TA_1 bitstring of 32 bit M_BO_NA_1 bitstring of 32 bit with time tag M_BO_TA_1 measured value, normalized value M_ME_NA_1 measured value, normalized value with time tag M_ME_TA_1 measured value, scaled value M_ME_NB_1 measured value, scaled value with time tag M_ME_TB_1 measured value, short floating point number M_ME_NC_1 measured value, short floating point number with time tag M_ME_TC_1 integrated totals M_IT_NA_1 integrated totals with time tag M_IT_TA_1 event of protection equipment with time tag M_EP_TA_1 packed start events of protection equipment with time tag M_EP_TB_1 packed output circuit information of protection equipment with time tag M_EP_TC_1 packed single-point information with status change detection measured value, normalized value without quality descriptor reserved for further compatible definitions Table 8.13a ASDU types – process information in monitoring direction M_PS_NA_1 M_ME_ND_1 Table 8.13b shows types that were added to this category with amendment 2 of IEC 60870-5-101. These provide for a longer time tag format.
