WARNING
NOTICE
Node-ID
The default Node-ID the sensor will claim on power up is user or factory
configurable. The user can configure by ”Commanded Address” service
according to the J1939 standard or by Peer-to-Peer message as described
below.
User configuration
User accessible parameters including node-id may be configured by peer-
to-peer proprietary A message PGN 0EF00h. The parameters are accessed
by byte-index and read/write operations coded in the data frame. The slave
will return the data frame including the acknowledge code. Parameter
values will be effective immediatly. On execution of ”Store Parameters” the
configuration is saved nonvolatile.
W
arning notice
•
Changing the parameters can cause a sudden step of the instantaneous
value and can result in unexpected machine (re)actions!
•
Precautions to prevent danger for man or machine are necessary!
•
Execute parametrizing at standstill of the machine only!
