Parameter
Data Bits
Parity
Stop Bits
Address range Levelmaster
The Levelmaster commands are based on the following syntax:
•
Capital letters are at the beginning of certain data fields
•
Small letters stand for data fields
•
All commands are terminated with "<cr>" (carriage return)
•
All commands start with "Uuu", whereby "uu" stands for the address (00-31)
•
"*" can be used as a joker for any position in the address. The sensor always converts this in
its address. In case of more than one sensor, the joker must not be used, because otherwise
several slaves will answer
•
Commands that modify the instrument return the command with "OK". "EE-ERROR" replaces
"OK" if there was a problem changing the configuration
Report Level (and Temperature)
Parameter
Request: Report Level (and Tem-
perature)
Response: Report Level (and Tem-
perature)
PV in inches will be repeated if "Set number of floats" is set to 2. Hence 2 measured values can be
transmitted. PV value is transmitted as first measured value, SV as seconed measured value.
Information:
If the temperature should be transmitted in the Levelmaster protocol, then TV must be set in the
sensor to temperature.
PV, SV and TV can be adjusted via the sensor DTM.
