R19: Manufacturer scaling – offset (B_h)
16-bit signed integer [0x0000]
This register contains the offset of the manufacturer's straight-line equation (1.5). The linear equation is
enabled via register R32.
R20: Manufacturer scaling – gain (A_h)
16 bits signed integer *2
-8
[0x00A0]
This register contains the scaling factor of the manufacturer's straight-line equation (1.5). The linear equation
is enabled via register R32.
R21: Additional offset register for two-wire connection
The value of register 1 at short cR1-RL1 or +R2-RL2 [approx. 0x01AX]
R31 to R47: User parameter area (SEEROM)
The user parameters are specific for each type of terminal. They can be modified by the programmer. The
user parameters are stored in a serial EEPROM in the terminal, and are retained in the event of voltage
drop-out. The user area is read-only 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 operation modes of the terminal. Thus, for instance, a user-specific scaling can be
enabled for the analog I/Os.
The feature register specifies the terminal's operation mode. [0x0106]
Feature bit no. Description of the operation mode
Bit 0 1 User scaling (R33, R44) active [0]
Bit 1 1 Manufacturer scaling (R19, R20) active [1]
Bit 2 1 Watchdog timer active [1]
In the delivery state, the watchdog timer is switched on.
Bit 3 1 Signed amount representation [0]
Signed amount representation is active instead of two's-complement
representation (-1 = 0x8001).
Bit 4 1 Siemens output format [0]
This bit is used for inserting status information on the lowest 3 bits (see
below).
Bit 5, 6 - reserved, do not change
Bit 7 1 activates filter constant in R37 [0]
Bit 8 1 Overrange Protection [1]
If the temperature exceeds 850 °C the status bits are correspondingly set
and the output value is restricted to 850 °C.
Bit 9 - reserved, do not change
Bit 10 1 Two-wire connection [0]
Bit 11 - reserved, do not change
Bit 12, 13, 14, 15 Element Valid measuring range
0 0 1 0 PT1000 0 °C ... 40 °C
0 1 0 1 NI1000 0 °C ... 40 °C
