The admissible data rate depends on a number of factors such as system pa-
rameters and cable length (
→ [4], [6]). It can be set on the gauge or pro-
grammed via DeviceNet.
By means of the "RATE" switch, the data rate can be set to 125
("1"), 250 ("2") or 500 kBaud ("5").
Default data rate setting is 500 kBaud.
If the switch is in any of the "P" positions, the data rate is pro-
grammable via DeviceNet (
→ [1]).
Two LEDs on the gauge inform on the gauge status and the current DeviceNet
status.
LED Description
Dark no supply
Red/green,
flashing
self test
Green normal operation
Red non recoverable error
LED Description
Dark gauge not online:
− self test not yet concluded
− no
supply,
→ "STATUS MOD" LED
Green,
flashing
gauge online but no communication:
− self test concluded but no communication to other nodes
established
− gauge not assigned to any master
Green gauge online; necessary connections established
Red, flashing one or several input / output connections in "time out" status
Red communication error. The gauge has detected an error that im-
pedes communication via the network (e.g. two identical node ad-
dresses (MAC IC) or "Bus-off")
The gauge is connected to the DeviceNet system via the 5-pin DeviceNet con-
nector (
→ 21).
