Either the ASDUs of the set <45> to <51> or of the set <58> to <64> are used.
Table 3-5: System information in monitor direction
Table 3-6: System information in control direction
Table 3-7: Parameter in control direction
Table 3-8: File transfer
Type identifier and cause of transmission assignments (station-specific parameters)
are shown in the following tables. In these tables, shaded boxes (░) are not
required, black boxes (█) are not permitted in the companion standard, empty cells
indicate the functions or ASDU are not used, and a cross (╳) indicates availability
only in the standard direction.
