3.7 Messages in the diagnostic buffer of the CPU
Software
424 System Manual, 07/2009, C79000-G8976-C222-07
The messages generated by TD7 are, however, only displayed in plain text when they are
called up in
SINAUT / TD7 CPU Diagnostics . If you call up the messages generated by TD7
in
STEP 7 Diagnostics / Module Information, Diagnostic Buffer tab , they are displayed in
hexadecimal format.
Note
If there is no text file with the diagnostic texts of the TD7 events on the PG with which the
diagnostic buffer is read out, the events are displayed in hexadecimal format.
Based on the following list, you can identify the significance.
3.7.1 SINAUT diagnostic messages of TD7onCPU
Classification of TD7 messages
The TD7onCPU software package uses the numeric range of event class B for its diagnostic
messages. This event class is reserved for user-defined events in STEP 7. It is, however,
used in SINAUT ST7 for SINAUT diagnostic messages.
Note
In SINAUT ST7, the user can only use event class A for user-defined diagnostic messages.
Just as in event class B, this is also reserved for user-defined messages in STEP 7.
The SINAUT diagnostic messages of TD7onCPU use the range from Bx00h to BxFFh. To
distinguish the individual messages, only in the last two numbers are significant, in other
words the range from 00h to FFh.
x is a placeholder for an ID that allows the global classification of messages. For the TD7
diagnostic messages, the IDs 0 and 1 are used for events exiting state (0) and entering state
(1).
Table 3- 21 Global classification of the SINAUT diagnostic messages of TD7onCPU
ID x Resulting event IDs Classification
0 B000h ... B0FFh Exiting state messages
1 B100h ... B1FFh Entering state messages
Most messages are entering state, only a few are existing state.
