Safety regulations
Before commencing the installation:
• Disconnect the power supply of the device.
• Ensure that devices cannot be accidentally restarted.
• Verify isolation from the supply.
• Earth and short circuit.
• Cover or enclose neighboring units that are live.
• Follow the engineering instructions of the device concerned.
• Only suitably qualified personnel in accordance with EN 50110-1/-2 (DIN VDE 0105
Part 100) may work on this device/system.
• Before installation and before touching the device ensure that you are free of electrostatic
charge.
• The functional earth (FE) must be connected to the protective earth (PE) or to the potential
equalization. The system installer is responsible for implementing this connection.
• Connecting cables and signal lines should be installed so that inductive or capacitive inter-
ference do not impair the automation functions.
• Install automation devices and related operating elements in such a way that they are well
protected against unintentional operation.
• Suitable safety hardware and software measures should be implemented for the I/O inter-
face so that a line or wire breakage on the signal side does not result in undefined states
in the automation devices.
• Ensure a reliable electrical isolation of the low voltage for the 24 volt supply. Only use
power supply units complying with IEC/HD 60364-4-41 (DIN VDE 0100 Part 410).
• Deviations of the mains voltage from the rated value must not exceed the tolerance limits
given in the specifications, otherwise this may cause malfunction and dangerous opera-
tion.
• Emergency stop devices complying with IEC/EN 60204-1 must be effective in all operating
modes of the automation devices. Unlatching the emergency-stop devices must not cause
restart.
• Devices that are designed for mounting in housings or control cabinets must only be
operated and controlled after they have been installed with the housing closed. Desktop or
portable units must only be operated and controlled in enclosed housings.
• Measures should be taken to ensure the proper restart of programs interrupted after a
voltage dip or failure. This should not cause dangerous operating states even for a short
time. If necessary, emergency-stop devices should be implemented.
• Wherever faults in the automation system may cause damage to persons or property,
external measures must be implemented to ensure a safe operating state in the event of
a fault or malfunction (for example, by means of separate limit switches, mechanical inter-
locks etc.).
• The electrical installation must be carried out in accordance with the relevant regulations
(e. g. with regard to cable cross sections, fuses, PE).

Safety regulations
4XI/ON: XNE-2CNT-2PWM 04/2011 MN05002035Z-EN www.eaton.com
• All work relating to transport, installation, commissioning and maintenance must only be
carried out by qualified personnel. (IEC/HD 60364 (DIN VDE 0100) and national work safety
regulations).
• All shrouds and doors must be kept closed during operation.

2 Getting Started - first steps for operating this module
2.1 General information about the module
XI/ON: XNE-2CNT-2PWM 04/2011 MN05002035Z-EN www.eaton.com 11
2 Getting Started - first steps for operating this module
2.1 General information about the module
The XNE-2CNT-2PWM provides 2 counter channels (CNT1 and CNT 2) with 3 count inputs
each DI0 (A), DI1 (B) and DI2 (Z) as well as 2 channels with 2 outputs each, P0 and P1
(frequency output) and D1 and D2 (direction).
2.1.1 Counter inputs
The module's counter inputs allow the connection of encoders as well as of count- and direc-
tion signals, with the direction evaluation being optional.
Operation modes
• Counting
– Pulse and direction, →see page 43
– AB mode, →see page 44
• Measurement
– Frequency measurement / rotational speed measurement, →see page 53
– Period duration measurement, →see page 55
2.1.2 PWM outputs
Each channel provides two PWM outputs P1/D1 and P2/D2.
P1 and P2 are used for frequency output.
The logical status of the outputs D1 and D2 can be used to define the rotation direction. The
outputs can also be used independently of the PWM.
The outputs Px serve to give out a square wave signal with a defined mark-to-space ratio, a
defined period duration and a defined number of pulses.
operation modes
• Period duration / duty cycle, →see page 61
• High time / low time definition, →see page 63

2.2 Getting Started
2.2.1 Count function
The following section describes the general procedure to read the count value of counter
CNT1 of XNE-2CNT-2PWM.
Prerequisites / start conditions
The default settings of the module parameters allow immediate access to the module's count
value.
• Parameterization:
mode CNT1 = 0000 = pulse/direction, single sample
(Parameter data of the module (page 25)).
The signals on input A1 are counted, the count direction is defined via signal B1.
Z1 can be used as a HW gate (→see below).
• Mapping of the count value into the process data:
The count value is mapped into the process data (Process input / check-back interface
(page 28)):
ADR AUX REG1 RD DATA = 0×20
→0×20 = register no. of REG_CNT1_CNT (actual count value of CNT1) →see also
Register interface (page 91).
→The count value is mapped into bytes 12 to 15 of the process data (→see also Process
input / check-back interface (page 28)).
Current count value
Process input / check-back interface (page 28), byte 12 to byte 15:
AUX_REG1_RD_DATA, Byte 0,
to
AUX_REG1_RD_DATA, Byte 3 contain the current count value of CNT1
Enable
The counter function unit of the CNT-inputs is generally enabled per default setting.
CNT1_ GENERAL_ DISABLE = 0
(→see Process output / control interface byte 0, bit 0, page 32).
The function unit can be generally disabled by setting
CNT1_ GENERAL_ DISABLE = 1.
The general enabling of the counter function unit is displayed via
STS_CNT1_ GENERAL_ EN = 1.
(→see Process input / check-back interface byte 0, bit 0, page 28).
1If the counter has to count from a defined start value, this value has to be written into the
load value register REG_CNT1_LOADVAL (→see Internal registers - reading and writing
(page 89)).
2A state change from 0 →1 in control bit CNT1_ SW_LR of the process output / control inter-
face executes a Latch Retrigger which is necessary to transfer the load value.
3An executed Latch Retrigger is confirmed in the process input / check-back interface with
MSG_CNT1_SW_LR = 1.
4The load value (REG_CNTx_LOADVAL) is transferred into the register for the current count
value CNT1 REG_CNTx_CNT (→see also Register interface (page 91)).

2.2 Getting Started
XI/ON: XNE-2CNT-2PWM 04/2011 MN05002035Z-EN www.eaton.com 13
5If the start conditions for the count operation are defined, the count operation has to be
enabled using either the HW or the SW gate.
5.1 The default parameterization allows an immediate enabling of the count function via
a signal at input Z (HW gate).
Parameters:
Mode Z1 = 0001 = HW gate CNT (→see Parameter data of the module (page 25))
or
5.2 If the SW gate is to be used to enable the counting, the user has to set the process
output bit
CNT1_ ENABLE 0 →1
(→see Process output / control interface (page 32), byte 0, bit 1.
6The count operation is enabled with CNT1_ ENABLE = 1.
7The pulses are counted according to the parameterized operation mode.
(→see Process input / check-back interface (page 28), byte 0, bit 1, STS_CNT1_ RUN = 1)
8In default parameterization, the data (→see above Prerequisites / start conditions
(page 12)) can be read out from registers AUX_REG1_RD_DATA, byte 0 to
AUX_REG1_RD_DATA, byte 3 (bytes 12 to 15 of the process input data /check-back inter-
face ((→see also Current count value (page 12)).

2.2.2 PWM function
The following section describes the current procedure to output pulses at PWM1 of
XNE-2CNT-2PWM:
Prerequisites / start conditions
The default parameterization fulfils all necessary prerequisites / start conditions for a pulse
output:
• Operation mode: Period duration / duty cycle definition, →see Parameter data of the
module (page 25) and Period Duration / Duty Cycle Definition (page 61)
• Period duration: 1000 Hz, →see REG_PWM1_PD (page 95)
• Duty cycle: 50 %, →see REG_PWM1_DC (page 95)
• PWM1_ SINGLE = 0 (continuous enable, →see Process output / control interface
(page 32)
Enable
The pulse output is generally enabled via the default settings.
PWM1_ GENERAL_ DISABLE = 0
(→see Process output / control interface byte 2, bit 0, page 32).
The pulse output can be generally disabled using PWM1_ GENERAL_ DISABLE = 1.
An enabled PWM function is displayed via
STS_PWM1_GENERAL_ EN = 1.
(→see Process input / check-back interface byte 4, bit 4, page 28).
1The user has to enable the pulse output using either the HW or the SW gate.
1.1 Hardware gate:
Input "Z" can be parameterized as HW gate for the pulse output:
Parameters:
Mode Z1 = 0001 = HW gate PWM (→see Parameter data of the module (page 25))
or
1.2 Software gate:
The software gate is set via the process output bit
PWM1_ ENABLE= 1.
(Process output / control interface byte 2, bit 1, page 32).
2The pulse output is enabled.
3The pulses are output according to the parameterized period duration and the parameter-
ized duty cycle (see above).
(→see Process input / check-back interface (page 28), byte 4, bit 5, STS_PWM1_RUN = 1)
Note
If a defined number of pulse is to be output, the bit PWM1_ SINGLE has to be set =
1 (Process output / control interface (page 32)) and the number of the pulses to be
output has to be defined via REG_PWM1_CNTSV (load value register of PWM1, reg-
ister no. 0 × 64, →see Chapter 9, Register interface (page 91)).

3.1 General information about the register interface
18 XI/ON: XNE-2CNT-2PWM 04/2011 MN05002035Z-EN www.eaton.com
3.1.1 Mapping register contents into process data
A subset of the data in the register interface is mapped into the Process data of the module
(page 28) in order to allow direct external access.
Bytes 8 -23 of the process data allow reading and writing 4 32-bit-registers of the register inter-
face and can be allocated as required.
Addressing registers to be mapped
The address assignment of the register contents to be mapped can be carried out via the
process data or via the module parameters:
1Address assignment via process data
The address for one register access is directly defined via the Process output / control
interface (page 32), byte 6 and 7 (REG_WR_ADR and REG_RD_ADR).
2Address assignment via parameters
The address of three further registers to be mapped may be defined via Parameter data of
the module (page 25), Byte 10 to Byte 15 (ADR_AUX_REG1_RD_DATA to
ADR_AUX_REG3_WR_DATA).
