Terminal configuration

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:

0 to 7

8 to 15 16 to 30 31 to 47 48 to 63

Process variables Type register Manufacturer parameters User parameters Extended user area

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.

4 KL6071

Terminal configuration

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.

R13: Data type register

R14: not used R15: Alignment bits (RAM)

The analog terminal is set to a byte limit in the terminal bus with the alignment bits.

Manufacturer parameters

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.

Terminal configuration

User parameters

Note

Extended application area

The KL6071 has no terminal specific registers!

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 been implemented.

3.4 Register communication with KL6071

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.

The control or status byte occupies the lowest address of a logical channel.

The corresponding register values are located in the following 2 data bytes (the BK2000 is an exception to the rule: here, an unused data byte is inserted after the control or status byte, thus setting the register value to a word limit).
