The analog input terminals

- KL304x process signals in the range between 0 and 20 mA

- KL305x process signals in the range between 4 and 20 mA with a resolution of 12 bits (4095 increments). They can supply the sensors from voltage fed in via the power contacts. The power contacts can optionally be supplied via the standard supply or via a feed terminal with electrical isolation.

Process data output format In the delivery state the process data are shown in two's complement form

(integer -1 corresponds to 0xFFFF). Other display types can be selected via the feature register (e.g. sign/amount representation, Siemens output format).

Process data The process data that are transferred to the Bus Coupler are calculated

using the following equations: X_adc: Output values of the A/D converter

Y_aus: Process data to PLC B_a,A_a: Manufacturer gain and offset compensation (R17, R18) B_h,A_h: Manufacturer scaling (R19, R20) B_w,A_w: User scaling (R33, R34)

a) Neither user nor manufacturer scaling are active: Y_a = (B_a + X_adc) * A_a (1.0) Y_aus = Y_a

b) Manufacturer scaling active (factory setting): Y_1 = B_h + A_h * Y_a (1.1) Y_aus = Y_1

c) User scaling active: Y_2 =B_w + A_w * Y_a (1.2) Y_aus = Y_2

d) Manufacturer and user scaling active: Y_1 = B_h + A_h * Y_a (1.3) Y_2 = B_w + A_w * Y_1 (1.4) Y_aus = Y_2

The equations of the straight line are activated via register R32.

Terminal configuration

6 KL304x and KL305x

Terminal configuration

The terminal can be configured and parameterized via the internal register structure. Each terminal channel is mapped in the Bus Coupler. Depending on the type of the Bus Coupler and the mapping configuration (e.g. Motorola/Intel format, word alignment etc.) the terminal data are mapped in different ways to the Bus Coupler memory. For parameterizing a terminal, the control and status byte also has to be mapped.

BK2000 Lightbus Coupler In the BK2000 Lightbus coupler, the control and status byte is mapped in

addition to the data bytes. This is always located in the low byte at the offset address of the terminal channel.

Example for KL3042 and KL3052:

Offset Terminal1 Channel1 = 0

Offset Terminal2 Channel1 = 4

KL3042

Offset Terminal2 Channel2 = 8

BK3000 Profibus coupler For the BK3000 Profibus coupler, the master configuration should specify

for which terminal channels the control and status byte is to be inserted. If the control and status byte are not evaluated, the terminals occupy 2 bytes per channel:

• KL3041 and KL3051: 2 bytes of input data

• KL3042 and KL3052: 4 bytes of input data

• KL3044 and KL3054: 8 bytes of input data

Example for KL3042 and KL3052:

Offset Terminal1 Channel1 = 0

Offset Terminal1 Channel2 = 3

Offset Terminal2 Channel1 = 6

BK4000 Interbus Coupler The BK4000 Interbus Coupler maps the terminals in the delivery state with

2 bytes per channel:

• KL3041 and KL3051: 2 bytes of input data

• KL3042 and KL3052: 4 bytes of input data

• KL3044 and KL3054: 8 bytes of input data

Parameterization via the fieldbus is not possible. If the control and status byte is to be used, the KS2000 configuration software is required.

Example for KL3042 and KL3052:

Offset Terminal1 Channel1 = 0

Offset Terminal2 Channel1 = 4

Offset Terminal1 Channel2 = 2

Offset Terminal2 Channel1 = 6

The control/status byte must be inserted for parameterization (KS2000).

Other Bus Couplers and further information

Further information about the mapping configuration of Bus Couplers can be found in the Appendix of the respective Bus Coupler manual under Master configuration.

Note

The Appendix contains an overview of possible mapping configurations depending on the parameters that can be set.

Parameterization with KS2000

The parameterizations can be carried out independently of the fieldbus system with the KS2000 configuration software via the serial configuration interface in the Bus Coupler.

Different operating modes or functionalities may be set for the complex

terminals. The General Description of Registers explains those register contents that are the same for all complex terminals.

The terminal-specific registers are explained in the following section. Access to the internal terminal registers is described in the Register

Communication section.

General Description of Registers

Complex terminals that possess a processor are able to exchange data bi-

directionally with the higher-level controller. These terminals are referred to below as intelligent Bus Terminals. These include analog inputs, analog outputs, serial interface terminals (RS485, RS232, TTY etc.), counter terminals, encoder interface, SSI interface, PWM terminal and all other parameterizable terminals.

8 KL304x and KL305x

The main features of the internal data structure are the same for all the intelligent terminals. This data area is organized as words and comprises 64 registers. The important data and parameters of the terminal can be read and set through this structure. It is also possible for functions to be called by means of corresponding parameters. Each logical channel in an intelligent terminal has such a structure (so a 4-channel analog terminal has 4 sets of registers).

This structure is divided into the following areas:

(A detailed list of all registers can be found in the Appendix.)

Process variables

8 to 15

Type register

16 to 30

Manufacturer parameters

31 to 47

User parameters

48 to 63

Extended user area

Process variables

R0 to R7 Registers in the terminal's internal RAM:

The process variables can be used in addition to the actual process image. Their function is 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 can contain additional diagnostic information. Parity errors, for instance, that occur in serial interface terminals during data transmission are indicated here.

R7: Command register

High-Byte_Write = function parameter Low-Byte_Write = function number High-Byte_Read = function result Low-Byte_Read = function number

Type register

R8 to R15: Registers in the internal ROM of the terminal

The type and system parameters are hard programmed by the manufacturer, and the user can read them but cannot change them.

R8: Terminal type

The terminal type in register R8 is needed to identify the terminal.

R9: Software version (X.y)

The software version can be read as a string of ASCII characters.

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

Related to R10, this contains the number of channels that are logically present. Thus for example a shift register that is physically present can perfectly well consist of several signal channels.

R12: Minimum data length

The particular byte contains the minimum data length for a channel that is to be transferred. If the MSB is set, the control and status byte is not necessarily required for the terminal function and is not transferred to the control, if the Bus Coupler is configured accordingly.

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).

Note

This documentation applies to all terminals from firmware version 3x. The version number can be found within the serial number on the right-hand side face of the terminal: xxxx3xxx

If the internal filter is activated via R32.11, the following filter constants can

be selected in R37 (not possible for KL3044 and KL3054). In the standard setting, the corresponding conversion time is 2.5 ms:

R37 Explanation

0x0000 2nd order FIR filter.

default value

0x0100 1st order IIR filter, cut-off frequency fg approx.1 kHz 0x0200 1st order IIR filter, cut-off frequency fg approx. 100 Hz 0x0300 1st order IIR filter, cut-off frequency fg approx. 50 Hz 0x0400 1st order IIR filter, cut-off frequency fg approx. 20 Hz 0x0500 1st order IIR filter, cut-off frequency fg approx. 10 Hz 0x0600 1st order IIR filter, cut-off frequency fg approx. 5 Hz 0x0700 1st order IIR filter, cut-off frequency fg approx. 1 Hz

The implemented IIR filters do not have any notch behavior, i.e., they do not explicitly suppress any frequency.

0x1000 50 Hz FIR filter

Averaging over 16 values and first notch 25 Hz

0x2000 60 Hz FIR filter

Averaging over 16 values and first notch 20 Hz

In contrast to the IIR filters, FIR filter have notch behavior. The timer settings of the notch filters are set via channel 0 of the terminal. This means that the 50 Hz filter on channel 0 and the 60 Hz filter on channel 1 cannot

be active simultaneously. Other values

No filter active

Control and Status byte

Control byte for process data exchange Gain and offset compensation

The control byte is transmitted from the controller to the terminal. It can be used

- in register mode (REG = 1

bin

) or

- during process data exchange (REG = 0

bin

). The control byte can be used to carry out gain and offset compensation for the terminal (process data exchange). This requires the code word to be entered in R31. The gain and offset of the terminal can then be compensated. The parameter will only be saved permanently once the code word is reset!

Bit 6 of the control byte specifies whether a register should be read or written. If bit 6 is not set, then a register is read out without modifying it. The value can then be taken from the input process image.

If bit 6 is set, then the user data is written into a register. As soon as the status byte has supplied an acknowledgement in the input process image, the procedure is completed (see example).

Bit 0 to 5: Address The address of the register that is to be addressed is entered into bits 0 to

Mapping

As already described in the Terminal Configuration section, each Bus Terminal is mapped in the Bus Coupler. In the delivery state, this mapping occurs with the default settings of the Bus Coupler for this terminal. The default setting can be changed with the KS2000 configuration software or with a master configuration software (e.g. TwinCAT System Manager or ComProfibus).

If the terminals are fully evaluated, they occupy memory space in the input and output process image.

The following tables provide information about the terminal mapping, depending on the conditions set in the Bus Coupler.
