Data Rate Setting
By means of the switch, the data rate can
be set to 125 (<1>), 250 (<2>) or 500 kBaud (<5>)
(default 500 kBaud).
If the switch is in the
position, the data rate is
programmable via the DeviceNet (
→  [4]).
Example: Data rate = 250 kBaud:

Transmitting measurement values
Depending on the Fieldbus standard used, the gauge can only
transmit measurement values when it is authorized by the
master.
When the gauge is put into operation, it is in the IDLE status
(provided there is no error) and the value defined in the Safe
State is transmitted instead of the measurement value.
Measurement values are transmitted in the EXECUTING status.
For the gauge to change from the IDLE to the EXECUTING
status, a start instruction must be executed or the I/O-Poll mode
must be started in the IDLE status.
Status LED
Two LEDs on the gauge inform on the gauge status and the
current DeviceNet status.
