2.2 Functional description
of any incremental encoders to the bus coupler or the PLC. A 16-bit
counter with a quadrature decoder and a 16-bit latch can be read, set or
activated. Besides the decoder inputs A, B, C, an additional latch input G1
(24 V) and a gate input G2 (24 V) for disabling the counter are available.
The 16-bit up / down counter mode can also be selected. In this mode of
operation, input B is the counting input.
1-fold, 2-fold or 4-fold evaluation of the encoder signals A, B, C in simple or
complementary form can be parameterized via the field bus.
The terminal is supplied as a 4-fold quadrature decoder with
complementary evaluation of the encoder signals A, B, C. For operation of
the encoder interface, the operating voltage of 24 V DC must be connected
to the terminal contacts in addition to the encoder inputs.
Starting from hardware state 03 (beginning from 6.18.98) the KL5101 has
new, additional features:
Incremental encoder with fault alarm outputs can be connected to the
Status input of the KL5101.
A period measurement with a resolution of 200 ns can also be performed.

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 (0-10V, -10-10V, 0-20mA, 4-20mA), the analog outputs
(0-10V, -10-10V, 0-20mA, 4-20mA), serial interface terminals (RS485,
RS232, TTY, data transfer terminals), 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 memory locations. 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:

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.

R8 - 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: Software version X.y
The software version can be read as an ASCII character string.
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.

Manufacturer parameters
R16 - R30 is the area of the "Manufacturer parameters" (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.

Extended application area
R31 - R47 "Application parameters" area (SEEROM)
The application parameters are specific to each terminal type. They can be
modified by the programmer. The application 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/O’s.

3.3 Control-/Status-Byte
3.3.1 Control byte in process transfer
The control byte is transferred from the controller to the terminal. It can be
used in the register mode (REG = 1) or in process data transfer (REG = 0).
Various actions are triggered in the the KL5101 with the control byte:

Name REG=0 - - - En_Latch_Ext_n Cnt_Set EN_LAT_EXT /
EN_LATC
RD_PERIOD
Bit Bit Function
3 En_Latch_Ext_n The external latch input is activated for negative
edge. With the first external latch impulse after
validity of the EN_Latch_Ext_n bit, the counter value
in the latch register is stored. The pulses that follow
have no influence on the latch register when the bit
is set. Attention must be paid to ensuring that the
corresponding latch valid bit (Latch_Ext_Val) has
been removed from the terminal before alerting of
the zero pulse. This functionality is adjustable in the
feature register (default).
2 Cnt_Set The counter is set to the value that is specified via
the process data with the rising edge of Cnt_Set.
1 En_Latch_Ext The external latch input is activated for positive
edge. With the first external latch impulse after
validity of the En_Latch_Ext bit, the counter value in
the latch register is stored. The pulses that follow
have no influence on the latch register when the bit
is set. Attention must be paid to ensuring that the
corresponding latch valid bit (Latch_Ext_Val) has
been removed from the terminal before alerting of
the zero pulse. This functionality is adjustable in the
feature register (default).
RD_Period The periods between two positive edges of the input
A are measured with a resolution of 200 ns. When
the bit is set, this period is output in the data bytes
D2, D3, D4. This functionality is adjustable in the
feature register.
0 En_Latch The zero point latch (C input) is activated. The
counter value is stored in the latch register with the
first external latch pulse after validity of the En_Latch
bit (this has priority over En_Latch_Ext). The pulses
that follow have no influence on the latch register
when the bit is set. Attention must be paid to
ensuring that the corresponding latch valid bit
(Latch_Val) has been removed from the terminal
before the zero pulse is alerted (the Latch_Val bit
cannot be removed from the terminal until the C
pulse has a low level).
For the external latch input:
The activation of the positive edge (En_Latch_Ext = 1) has priority to the
Note
activation of the negative edge (En_Latch_Ext_n = 1).

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).

3.5 Mapping in the bus coupler
Each terminal channel 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 Beckhoff KS2000
configuration software or using master configuration software (e.g.
ComProfibus or TwinCAT System Manager). The following tables provide
information on how the KL5101 maps itself in the bus coupler depending
on the set parameters.
Mapping in the bus coupler The KL5101 is mapped in the bus coupler depending on the set
parameters. The terminal is always evaluated completely, the terminal
occupies memory space in the process image of the input and outputs.

terminal is mapped differently in the memory of the bus coupler depending
on the type of the bus coupler and on the set mapping configuration (e.g.
Motorola/ Intel format, word alignment,...). Contrary to the analog input and
output terminals, in the case of the KL5101 the control and status byte is
always mapped regardless of the higher-level field bus system.
byte is also always (i.e. in the case of all analog terminals) mapped in
addition to the data bytes. It is always in the low byte at the offset address
of the terminal channel.

4.1 ATEX - Special conditions
Observe the special conditions for the intended use of
Beckhoff fieldbus components in potentially explosive areas (directive
94/9/EU)!
WARNING
The certified components are to be installed in a suitable housing that guar-
antees a protection class of at least IP54 in accordance with EN 60529! The
environmental conditions during use are thereby to be taken into account!
If the temperatures during rated operation are higher than 70°C at the feed-
in points of cables, lines or pipes, or higher than 80°C at the wire branching
points, then cables must be selected whose temperature data correspond
to the actual measured temperature values!
Observe the permissible ambient temperature range of 0 - 55°C for the use
of Beckhoff fieldbus components in potentially explosive areas!
Measures must be taken to protect against the rated operating voltage be-
ing exceeded by more than 40% due to short-term interference voltages!
The individual terminals may only be unplugged or removed from the Bus
Terminal system if the supply voltage has been switched off or if a nonexplosive atmosphere is ensured!
The connections of the certified components may only be connected or dis-
connected if the supply voltage has been switched off or if a non-explosive
atmosphere is ensured!
The fuses of the KL92xx power feed terminals may only be exchanged if
the supply voltage has been switched off or if a non-explosive atmosphere
is ensured!
Address selectors and ID switches may only be adjusted if the supply volt-
age has been switched off or if a non-explosive atmosphere is ensured!
Operation of the Bus Terminal System in potentially explosive areas (ATE X)!
