Warning 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!
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 a ccessed
by byte-index and read/write operations coded in the data f rame. The s lave
will return the data frame including the acknowledge code. Parameter
v alues will be effective immediatly. On execution of "Store Parameters" the
configuration is saved nonvolatile.
