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 ADC raw value (X_R)
This register contains the raw ADC value with gain and offset error
• R1 to R5: Reserved
• R6: Diagnostic register
◦ High byte: reserved
◦ Low byte: Status byte
• R7: Command register
High-Byte_Write = function parameter
Low-Byte_Write = function number
High-Byte_Read = function result
Low-Byte_Read = function number
