IM 253-xDPx1 - DP-V1 slave - Diagnostic functions
PROFIBUS DP provides an extensive set of diagnostic functions for quick
error localization. Diagnostic messages are transferred via the bus and
collected by the master.
At the DP-V1 the device related diagnostic has been improved as further
function and is subdivided into the categories alarms and status messages.
Additionally in the DP-V1 slave from VIPA the last 100 alarm messages are
stored in a RAM res. in the flash with a time stamp and may be evaluated
with a software.
For this, please call the VIPA hotline!
The system also stores diagnostic messages like the states "Ready" res.
"DataExchange" that are not passed on to the master.
With every status change between "Ready" and "DataExchange" the
PROFIBUS slave stores the diagnostic-RAM content in a Flash-ROM and
writes it back to the RAM at every reboot.
With the short setting of 00 at the address lever you may save the
diagnostic data in the Flash-ROM during "DataExchange".
At voltage failure res. decreasing voltage a time stamp is stored in the
EEPROM. If enough voltage is still left, a diagnostic output to the master
occurs.
At the next reboot an undervoltage/shut-down diagnostic message is
generated from the time stamp of the EEPROMs and is stored in the
Diagnostic-RAM.
