E
When using an unbalanced link layer, the following Application Service Data Unit (ASDU) types are returned in class 2
messages (low priority) with the indicated causes of transmission:
The standard assignment of ASDUs to class 2 messages is used as follows:
A special assignment of ASDUs to class 2 messages is used as follows:
5.
APPLICATION LAYER
Transmission Mode for Application Data:
Mode 1 (least significant octet first), as defined in Clause 4.10 of IEC 60870-5-4, is used exclusively in this companion
standard.
Common Address of ASDU:
One Octet
Two Octets
Information Object Address:
One Octet
Structured
Two Octets
Unstructured
Three Octets
Cause of Transmission:
One Octet
Two Octets (with originator address). Originator address is set to zero if not used.
Maximum Length of APDU:
253
(the maximum length may be reduced by the system.
Selection of standard ASDUs:
For the following lists, the boxes indicate the following:
– used in standard direction;
– not used;
– cannot be
selected in IEC 60870-5-104 standard.
