5.4 Register description
The registers can be read or written via the register communication. They are used for the parameterization
of the terminal.
R0 to R7: Registers in the internal RAM of the terminal
The process variables can be used in addition to the actual process image. Their function is specific to the
terminal.
• R0 to R4: reserved
• R5: Raw DAC value (Y_dac)
The 16-bit value transferred to the D/A converter is called raw DAC value. It is calculated from the
process data via the manufacturer and user scaling.
• R6 to R7: reserved
R8 to R15: Registers in the internal ROM of the terminal
The type and system parameters are hard programmed by the manufacturer, and the user can read them
but cannot change them.
• R8: Terminal type
The terminal type in register R8 is needed to identify the terminal.
• R9: Software version (X.y)
The software version can be read as a string of ASCII characters.
