Accessing diagnostics messages
The diagnostics functions enable you to quickly localize any errors, which
occur. The following diagnostics options are available:
•
Diagnostics via the CP-LEDs
•
Diagnostics via diagnostic buffer of the corresponding CP
The CP-LEDs give you an initial overview of any internal or external error
as well as interface-specific errors.
More information about the LEDs and their function may be found at the
chapter "Hardware description".
Each CP part has its own diagnostic buffer. There every diagnostic event
of the CP is stored in the order, in which they occur.
The diagnostic buffer is a ring buffer for a maximum of 100 diagnostic
entries. When the diagnostic buffer is full, the oldest entry is deleted when
a new entry is recorded. This means that the most recent entry is always
the first.
The diagnostics buffer of the corresponding CP may be accessed by
means of the handling block SFC 59 RD_REC "Read record" with the
record set 80 for COM1 respectively record set 81 for COM2.
Here every CP part responses with a record set of 200byte.
The following errors may be reported:
•
Hardware respectively firmware errors
•
Initialization and parameterization errors
•
Errors during execution of a CPU request
•
Data transmission error (send and receive errors)
Note!
The contents of the diagnostic buffer is lost in the event of a PowerOFF.
