Firm and hardware version

The documentation refers to the firm and hardware status that was valid at the time it was prepared.

The properties of the modules are subject to continuous development and improvement. Modules having

earlier production statuses cannot have the same properties as modules with the latest status. Existing

properties, however, are always retained and are not changed, so that these modules can always be

replaced by new ones.

The firmware and hardware version (delivery state) can be found in the batch number (D number) printed at

the side of the EtherCAT Box.

2 Product overview

2.1 EtherCAT Box - Introduction

The EtherCAT system has been extended with EtherCAT Box modules with protection class IP67. Through

the integrated EtherCAT interface the modules can be connected directly to an EtherCAT network without an

additional Coupler Box. The high-performance of EtherCAT is thus maintained into each module.

The extremely low dimensions of only 126x30x26.5 mm (hxw xd) are identical to those of the Fieldbus

Box extension modules. They are thus particularly suitable for use where space is at a premium. The small

mass of the EtherCAT modules facilitates applications with mobile I/O interface (e.g. on a robot arm). The

EtherCAT connection is established via screened M8connectors.

Fig.1: EtherCAT Box Modules within an EtherCAT network

The robust design of the EtherCAT Box modules enables them to be used directly at the machine. Control

cabinets and terminal boxes are now no longer required. The modules are fully sealed and therefore ideally

prepared for wet, dirty or dusty conditions.

Pre-assembled cables significantly simplify EtherCAT and signal wiring. Very few wiring errors are made, so

that commissioning is optimized. In addition to pre-assembled EtherCAT, power and sensor cables, field-

configurable connectors and cables are available for maximum flexibility. Depending on the application, the

sensors and actuators are connected through M8 or M12connectors.

The EtherCAT modules cover the typical range of requirements for I/O signals with protection class IP67:

• digital inputs with different filters (3.0ms or 10μs)

• digital outputs with 0.5 or 2A output current

• analog inputs and outputs with 16bit resolution

• Thermocouple and RTD inputs

• Stepper motor modules

XFC (eXtreme Fast Control Technology) modules, including inputs with time stamp, are also available.

Fig.4: EP3162-0002

2-channel analog input ± 10V or 0/4...20mA, electrically isolated, single-ended, 16-bit

The EP3162 EtherCAT Box has two analog inputs that can be individually parameterized to process signals

either in the range from -10V to +10V or from 0/4mA to 20mA. The voltage or input current is digitized with

a resolution of 16bits, and is transmitted (electrically isolated) to the higher-level automation device.

The two input channels are electrically isolated from each other. The input filter and therefore the conversion

times are configurable in a wide range. The inputs can, if required, be scaled differently, and automatic limit

value monitoring is also available. EtherCAT is used for parameterization purposes. The parameters are

stored in the module.

Analog inputs (single-ended)

The EP3182-1002 EtherCAT Box has two analog inputs which can be individually parameterized, so that

they process signals either in the -10V to +10V range or the 0/4mA…20mA range.

The voltage or input current is digitized with a resolution of 16bits, and is transmitted (electrically isolated) to

the higher-level automation device.

The two input channels are single-ended and share a common internal ground potential. The input filter and

therefore the conversion times are configurable in a wide range.

The inputs can, if required, be scaled differently, and automatic limit value monitoring is also available.

EtherCAT is used for parameterization purposes. The parameters are stored in the module.

Digital outputs

In addition, the EP3182-1002 EtherCAT Box has two digital outputs via which it forwards the binary control

signals from the controller to the actuators at the process level.

These two outputs (sink/source type) are intended for the switching of logic inputs or outputs with a minimum

impedance of 10kOhm (e.g. reset inputs of digital sensors) and can process currents up to 2mA. They

indicate their signal state by LEDs and are short-circuit proof.

The signals are also connected via the two M12 connectors.
