R14: Reserved
R15: Alignment bits (RAM) –
The alignment bits are used to place the analog terminal in the
Bus Coupler on a byte boundary.
5.4.4 Manufacturer
Parameters
R16 to R30: Manufacturer parameter area (SEEROM) –
The manufacturer parameters are
specific for each type of terminal. They are programmed by the manufacturer, but can also be
modified by the controller. The manufacturer parameters are stored in a serial EEPROM in the
terminal, and are retained in the event of voltage drop-out. These registers can only be altered
after a code-word has been set in R31.
5.4.5 User
Parameters
R31 to R47: User parameter area (SEEROM) –
The application parameters are specific for each
type of terminal. They can
be modified by the programmer. The application parameters are stored
in a
serial EEPROM in the terminal, and are retained in the event of voltage
drop-out. The user
area is write-protected by a code-word.
R31: Code-word register in RAM –
The code-word
0x1235
must be entered here so that
parameters in the
user area can be modified. If any other value is entered into this register,
the
write-protection is active. When write protection is not active, the code
word is returned when the
register is read. If the write protection is active,
the register contains a zero value.
R32: Feature register –
This register specifies the terminal's operating modes. Thus, for
instance, a
user-specific scaling can be activated for the analog I/Os.
R33 to R47 Terminal-specific Registers –
The function of these registers depends on the
respective terminal type (see terminal-specific register description).
