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").
If the switch is in any of the "P" positions, the data rate is pro-
grammable via DeviceNet (
→ [1]).
Two lights (LEDs) on the gauge inform on the gauge status and the current
DeviceNet status.
Light status Description
Dark No supply
Flashing
red/green
Selftest
Green Normal operation
Red Non recoverable error
Light status Description
Dark Gauge not online:
− Selftest not yet concluded
− No supply, → "STATUS MOD" light
Flashing
green
Gauge online but no communication:
− Selftest concluded but no communication to other nodes
established
− Gauge not assigned to any master
Green Gauge online; necessary connections established
Flashing red One or several input/output connections in "timed 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 (
→ 22).
