Addressing levels of diagnostics data records
Diagnostics and configuration data is evaluated at the following addressing levels:
•
Device level
•
AR (Application Relation)
•
API (Application Process Identifier)
•
Slot
•
Subslot
A group of diagnostics and configuration data records are available for each address level
(exception: device level always 0xF80c). In HEX representation, the individual groups of data
records are distinguished by the first letter of the data record number.
Figure 4-14 Addressing levels of diagnostics data records
The information for each IO device (addressing level AR), module (addressing level slot) or
submodule (addressing level subslot) is always transferred in separate diagnostics or
configuration data records. The data record returns diagnostics data or configuration data for
one or more subslots, slots and APIs, depending on the addressing level.
Note
The diagnostics information is only generated for configured modules / submodules /
channels.
