208 Practical Modern SCADA Protocols: DNP3, 60870.5 and Related Systems Type No. Description Reference single command C_SC_NA_1 double command C_DC_NA_1 regulating step command C_RC_NA_1 set point command, normalized value C_SE_NA_1 set point command, scaled value C_SE_NB_1 set point command, short floating point number C_SE_NC_1 bitstring of 32 bits C_BO_NA_1 Table 8.13c ASDU types – process information in control direction Type No. Description Reference end of initialization M_EI_NA_1 reserved for further compatible definitions Table 8.13d ASDU types – system information in monitor direction Type No. Description Reference interrogation command C_IC_NA_1 counter interrogation command C_CI_NA_1 read command C_RD_NA_1 clock synchronization command C_CS_NA_1 test command C_TS_NA_1 reset process command C_RP_NA_1 delay acquisition command C_CD_NA_ reserved for further compatible definitions Table 8.13e ASDU types – system information in control direction Type No. Description Reference parameter of measured value, normalized value P_ME_NA_1 parameter of measured value, scaled value P_ME_NB_1 parameter of measured value, short floating point number P_ME_NC_1 parameter activation P_AC_NA_1 reserved for further compatible definitions Table 8.13f ASDU types – parameter in control direction

Fundamentals of IEC 60870-5 209 Type No. Description Reference file ready F_FR_NA_1 section ready F_SR_NA_1 call directory, select File, call File, call section F_SC_NA_1 last section, last segment F_LS_NA_1 ack File, ack section F_AF_NA_1 segment F_SG_NA_1 directory F_DR_TA_1 reserved for further compatible definitions Table 8.13g ASDU types – file transfer Variable structure qualifier The variable structure qualifier is a single-octet that specifies the number of information objects or information elements, and how they are addressed. It contains a seven-bit binary number, and a 1-bit field that indicates which of two different possible information structures are used. Figure 8.17 shows the variable structure qualifier field, followed by a detail of the two information structures.
