Information object address
(System-specific parameter)
One octet Structured
Two octets Unstructured
⌧ Three octets
Cause of transmission
(System-specific parameter)
One octet ⌧ Two octets (with originator address)
Length of APDU
(System-specific parameter, specify the maximum length of the APDU per
system)
The Maximum length of the APDU is 2 46 (default). The maximum length may be
reduced by the system.

4.8.3 Selection of standard ASDUs
Process information in monitor direction
(Station-specific parameter, mark each Type ID 'X' if it is only used in the
standard direction, 'R' if only used in the reverse direction, and 'B' if used in both
directions)
