The structure of the entry in the diagnostic buffer is as follows:
Byte Contents
1, 2 Event ID
3 Priority class
4 OB number
5, 6 reserved
7, 8 Additional information 1
9, 10, 11, 12 Additional information 2
13 ... 20 Time stamp:
The data type of the time stamp is Date_and_Time.
Every event is assigned to an event ID.
The additional information contains more specific information about the event. This infor-
mation differs for each event. When a diagnostic event is generated the contents of these
entries may be defined by the user.
When a user defined diagnostic message is sent to the partners this additional informa-
tion may be integrated into the (event-ID specific) message text as an associated value.

have registered for this purpose. Sending is only initiated when one or more partners
have registered and the send buffer is not full. Messages are sent asynchronously with
respect to the application program.
The event ID of the user event is entered into EVENTN. Event IDs must be of the format
8xyzh , 9xyzh, Axyzh and Bxyzh. Here the IDs of format 8xyzh and 9xyzh refer to prede-
fined events and IDs of format Axyzh and Bxyzh refer to user-defined events.
An event being activated is indicated by x = 1,
an event being deactivated by x = 0.
