R14: not used
R15: Alignment bits (RAM)
The analog terminal is set to a byte limit in the terminal bus with the align-
ment bits.
Manufacturer parameters R16 - R30 is the area of the "Manufacturer parameters" (SEEROM)
The manufacturer parameters are specific to each terminal type. They are
programmed by the manufacturer but can also be modified from the control
system. The manufacturer parameters are stored permanently in a serial
EEPROM and are therefore not destroyed by power failures.
These registers can only be modified after setting a code word in R31.
User parameters

Note
R31 - R47 "Application parameters" area (SEEROM)
The application parameters are specific to each terminal type. They can be
modified by the programmer. The application parameters are stored per-
manently in a serial EEPROM in the terminal and cannot be destroyed by
power failures. The user area is write protected over a Codeword.
R31: Code word-register in the RAM
The code word 0x1235 must be entered here to enable modification of
parameters in the user area. Write-protection is set if a different value is
entered in this register. When write protection is inactive, the code word is
returned during reading of the register. The register contains the value zero
when write protection is active.
R32: Feature-register
This register defines the operating modes of the terminal. For example, a
user-specific scaling can be activated for the analog I/O’s.
R33 - R47
Registers that depend on the terminal type
Extended application area
R47 - R63
These registers have not yet been implemented.
