Register Description
12 KL3201, KL3202 and KL3204
R13: Data type register
Data type register
0x00 Terminal with no valid data type
0x01 Byte array
0x02 Structure 1 byte n bytes
0x03 Word array
0x04 Structure 1 byte n words
0x05 Double word array
0x06 Structure 1 byte n double words
0x07 Structure 1 byte 1 double word
0x08 Structure 1 byte 1 double word
0x11 Byte array with variable logical channel length
0x12 Structure 1 byte n bytes with variable logical channel
length (e.g. 60xx)
0x13 Word array with variable logical channel length
0x14 Structure 1 byte n words with variable logical channel
length
0x15 Double word array with variable logical channel length
0x16 Structure 1 byte n double words with variable logical
channel length
R14: Reserved
R15: Alignment bits (RAM)
The alignment bits are used to place the analog terminal in the Bus
Coupler on a byte boundary.
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.
User parameters 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 write-protected by a code-word.

Note
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).
Extended application region
R47 to R63
Extended registers with additional functions.
