Error behavior and interrupts
The system shows the following error behavior ...
n
... at gaps in the
‘slot’
configuration:
–
If the configuration of the I-Device contains gaps in the
‘slot’
configuration (i.e.
there are free
‘slots’
before used
‘slots’
), the configuration is rejected and
0xEA64 is returned as a configuration error in the diagnostic buffer.
–
If the configuration of the higher-level IO controller contains gaps in the
‘slot’
con-
figuration (i.e. there are free
‘slots’
before used
‘slots’
), the connection is rejected
with the PN IO Status
ErrorCode1
= 0x40 and
ErrorCode2
= 0x04
(AR_OUT_OF_RESOURCE).
n
... at modules, which differ from the configured:
–
A
ModuleDiffBlock
is generated and the wrong modules are not served.
n
... if the number of configured modules in the IO controller is greater than the number
of configured modules in the I-Device:
–
The IO controller receives a
ModuleDiffBlock
with ModuleStatus "NoModule" for
modules that are not configured in the I-Device. The I-Device sets the status of
the non-configured modules to "bad".
n
... if the number of configured modules in the I-Device is greater than the number of
configured modules in the IO controller:
–
The IO controller does not receive an error because the additional modules are
unknown.
Starting position
IO controller in RUN, I-Device in RUN
Event
I-Device CPU goes to STOP
Reaction
n
An OB 85 is called in the IO controller for each input and output transfer
area, which is located in the process image, if messages of process image
transfer errors are parametrized.
n
An OB 122 is triggered in the IO controller for each peripheral direct access
to an input or output transfer area.

an input transfer area.
Note: Output transfer areas can still be accessed!
