Safety module diagnostic objects
rameter ru52 to the safety module. Please note that only data from 01.01.2014 are ac-
cepted by the safety module type 5. By writing "2" in subindex 11, the time is taken over
from the safety module into parameters ru52 and ru53.
Subindex 12 can be used to activate the LED flashing. This indicates the current flashing
status of the safety module. "1" indicates "flashing active", "0" indicates "flashing inac-
tive". Writing the corresponding values to this parameter leads to the respective function-
ality.
In addition, it is possible to read out the last ten protocol or log entries of certain error cat-
egories of the safety module, which can also be read out via COMBIVIS. For this pur-
pose, a configuration parameter (sm18), a status parameter (sm19) and ten protocol in-
formation parameters (sm20 to sm29) are available.
Parameter sm18 is used to select the error category to be read out. Writing the parameter
starts the readout of the log.
The reading of the log is deactivated.
The entries in the "error" category are read out from the safety mod-
ule when this value is written.
The entries in the "safety function request“ category are read out
from the safety module when this value is written.
The entries in the "configuration errors“ category are read out from
the safety module when this value is written.
The entries in the "bus errors“ category are read out from the safety
module when this value is written.
The entries in the "bus configuration errors“ category are read out
from the safety module when this value is written.
bus safety function re-
quest
The entries in the "bus safety function request“ category are read
out from the safety module when this value is written.
Parameter sm19 indicates the actual status of the readout and possible errors. It can
therefore only be read.
log read out timeout
error
The readout could not be completed within 5 seconds. Please check
the status and connection to the safety module and try again.
The log is currently being read out.
The log read out was finished successfully.
The parameters read from the safety module are written in structures sm20 to sm29 and
contain information on errors of the category selected in sm18. The structure corresponds
to the structure of the protocol in the Safety Wizard in COMBIVIS 6. The entry with the
lowest log entry number (-> "log entry 0") contains the latest information. The "date and
time" specification can be inconsistent, depending on the time of configuration by the
user. However, the sequence of parameters sm20 to sm29 is always correct. Sub-indices
5 and 6 differ only in the plaintexts assigned to the explicit values. They are filled accord-
ing to the selected category (see sm18). Thus, sub-index 5 contains the details of catego-
ries 3 and 8, whereas sub-index 6 contains the details of categories 0, 5, 6, and 7. The
value of the sub-index that is not required is filled with "0" (the plaintext for "0" is conse-
quently invalid in this case).
