3.2 Register description
The complex terminals can be adjusted to different operating modes or
functionalities. The General Description of Register describes the contents
of the registers, which are identical for all complex terminals.
The terminal-specific registers are explained in the section following to it.
The access to the internal registers of the terminal is described in the
section Register Communication.
3.2.1 General register description
Complex terminals that possess a processor are capable of bidirectionally
ex-changing data with the higher-level control system. Below, these
terminals are referred to as intelligent bus terminals. They include the
analog inputs, the analog outputs, serial interface terminals (RS485,
RS232, TTY etc.), counter terminals, encoder interfaces, SSI interfaces,
PWM terminals and all other parameterizable terminals.
Internally, all intelligent terminals possess a data structure that is identical
in terms of it's essential characteristics. This data area is organized in
words and embraces 64 registers. The essential data and parameters of
the terminal can be read and adjusted by way of the structure. Function
calls with corresponding parameters are also possible. Each logical
channel of an intelligent terminal has such a structure (therefore, 4-channel
analog terminals have 4 register sets.

This structure is broken down into the following areas:

Process variables
R0 to R7: Registers in the terminal’s internal RAM
The process variables can be used in additional to the actual process
image and their functions are specific to the terminal.
R0 to R5: Terminal specific registers
The function of these registers depends on the respective terminal type
(see terminal-specific register description).
R6: Diagnostic register
The diagnostic register may contain additional diagnostic information. In
the case of serial interface terminals, for example, parity errors that have
occurred during data transfer are indicated.
R7: Command register
High-Byte_Write = function parameter
Low-Byte_Write = function number
High-Byte_Read = function result
Low-Byte_Read = function number
Type registers
R8 to R15: Registers in the terminal’s internal ROM
The type and system parameters are programmed permanently by the
manufacturer and can only be read by the user but cannot be modified.
R8: Terminal type:
The terminal type in register R8 is needed to identify the terminal.
R9: Firmware version X.y
The firmware version can be read as an ASCII character string.
3.2.1.1 R10: Data length
R10 contains the number of multiplexed shift registers and their length in
bits.
The bus coupler sees this structure.
R11: Signal channels
In comparison with R10, the number of logically existing channels is
located here. For example, one physically existing shift register may
consist of several signal channels.
R12: Minimum data length
The respective byte contains the minimum data length of a channel to be
transferred. If the MSB is set, then the control/status byte is not necessarily
needed for the function of the terminal and, with appropriate configuration
of the coupler, is not transferred to the control system.

R15: Alignment bits (RAM)
The analog terminal is set to a byte limit in the terminal bus with the
alignment bits.
R16 to R30: Manufacturer parameter area (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.
R31 to R47: User parameter area (SEEROM)
The user parameters are specific to each terminal type. They can be
modified by the programmer. The user parameters are stored permanently
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/Os.
R33 to R47
Registers that depend on the terminal type
R47 to R63
These registers have not yet been implemented.

3.2.2 Terminal-specific register description
The KL1512 has no terminal specific registers!
3.3 Control and Status Byte
The control byte is transmitted from the controller to the terminal. It can be
used
- in register mode (REG = 1
- during process data exchange (REG = 0
bin
) or

Control byte during process data exchange
The control byte triggers various actions in the counter terminal KL1512

The counter is set to the value that is specified via the

If this bit is set, the counter is stopped. The present
counter value is saved.

If this bit is set, the counter is stopped,
- if it reaches 0xFFFF while counting forwards
- if it reaches 0x0000 while counting backwards
The counter is set to the value 0x0000. Setting of the
counter is edge controlled.
If this bit is set, the counter is decremented with every
positive edge.
Status byte during process data exchange
The status byte is transferred from the terminal to the control system. It
acknowledges the bits of the control byte.:

Bit 7=1: register mode
When bit 7 of the control byte is set, the first two bytes of the user data are
not used for process data transfer, but are written into or read out of the
terminal’s register.
Bit 6=0: read
Bit 6=1: write
In bit 6 of the control byte, you define whether a register is to be read or
written. When bit 6 is not set, a register is read without modification. The
value can be taken from the input process image.
When bit 6 is set, the user data is written into a register. The operation is
concluded as soon as the status byte in the input process image has
supplied an acknowledgement (see examples).
Bits 0 to 5: address The address of the register to be addressed is entered in bits 0 to 5 of the
control byte.

4 Appendix
As already described in the chapter terminal configuration, each bus
terminal is mapped in the bus coupler. In the standard case, this mapping
is done with the default setting in the bus coupler / bus terminal. This
default setting can be modified with the KS2000 configuration software or
using master configuration software (e.g. ComProfibus or TwinCAT System
Manager). The following tables provide information on how the KL1512
maps itself in the bus coupler depending on the set parameters.
