5.5.6 CAN module FI 810FCAN module of the FieldController. The CAN module allows the connection of a maximum of 5
I/O units and thus the connection of 45 I/O modules in the way in which they are also used in the
conventional Freelance 2000 D-PS process station. Below the CAN module, a CAN master must
be configured.
For further parameter information and object data, see Parameterization of AC 800F, page 20
and Diagnostic data for objects, page 28.
For each FieldController, it is possible to connect only one station bus (CAN) line with
maximum 5 racks. The slot of the FI 820F module is preset to F1 and cannot be changed.
If a CAN module is installed in slot F1 of the FieldController, then the CAN bus must be ac tivated in the boot parameters of the resource. If a different module is installed in slot F1,
the CAN bus must be deactivated.
5.6 Diagnostic data for objects
In addition to the I/O components of an object, certain diagnostic data can be evaluated; variables
are assigned to the diagnostic components and are then evaluated in programs.
Objects Description Name Data type
All High temperature TMP BOOL
All Module fault ERR BOOL
All Error code STA UDINT

For these modules of the FieldController, a message
can only be sent if the FieldController operating system
is loaded.

5.6.1 STA Error codes
If "Module fault" is reported for the module, correct operation of the I/O module is not guaranteed
and no data are transmitted. The errors are saved bit-coded in the error code. The following are
possible error causes:
Error
code
bit
Error
code
decimal
Fault Cause
0 0 Self-test error The I/O module has detected a non-tolerable
error in its cyclic self-test
1 2 Configuration doesn't
match
The configured module type doesn't match the
connected I/O module.
2 4 Boot test error Boot test of the I/O module was unsuccessful
3 8 Slot not used The module configuration has been loaded but
the module is not mounted.
4 16 Communication error I/O module has not correctly signaled in the
given period (no keep alive signal)
