11.5 Levelmaster commands
The VEGAPULS 63 is also suitable for connection to the following RTUs with Levelmaster protocol.
The Levelmaster protocol is often called "Siemens" "Tank protocol".
RTU Protocol
ABBTotalow Levelmaster
Kimray DACC 2000/3000 Levelmaster
Thermo Electron Autopilot Levelmaster
Parameters for the bus communication
The VEGAPULS 63 is preset with the default values:
Parameter CongurableValues Default Value
Baud Rate 1200, 2400, 4800, 9600, 19200 9600
Start Bits 1 1
Data Bits 7, 8 8
Parity None, Odd, Even None
Stop Bits 1, 2 1
Address range Levelmaster 32 32
The Levelmaster commands are based on the following syntax:
•
Capitallettersareatthebeginningofcertaindataelds
•
Smalllettersstandfordataelds
•
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"iftherewasaproblemchangingtheconguration
