Firmware and hardware versions

This documentation refers to the firmware and hardware version that was applicable at the time the

documentation was written.

The module features are continuously improved and developed further. Modules having earlier production

statuses cannot have the same properties as modules with the latest status. However, existing properties

are retained and are not changed, so that older modules can always be replaced with new ones.

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

the side of the EtherCATBox.

Syntax of the batch number (D-number)

D: WW YY FF HH

WW - week of production (calendar week)

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: EP9224-0037

EP9224-0037

The EP9224-0037 EtherCAT Box distributes an EtherCAT signal to four EtherCATP ports.

It measures supply voltages, output currents and its own temperature. The measured values are available as

process data.

Internal protective functions use the measured values to switch off the output voltages of the EtherCATP

ports in case of error. This prevents damage and malfunctions:

• Overloading of the supply line

• Overloading of the power supply unit

• Overloading of the EtherCATP cables

• Undervoltage of the supply voltages

EP9224-0037 has a peak value detector and a data logger for the diagnosis of errors.

EP9224-0037 17Version: 1.0

3.1.2 Mounting

Mount EtherCAT Box modules with two M4 screws in the centrally located fixing holes.

The screws must be longer than 15mm. The fastening holes in the modules have no thread.

Protect connectors against soiling

Protect all module connections from soiling during installation! The protection classes IP65, IP66,

IP67 (in accordance with EN 60529) are ensured only if all connectors are wired or sealed! Unused

connectors must be sealed with suitable protective caps (see Beckhoff catalog for connector sets

and protective caps)!

Cooling plate

The EP9224-0037 module has a cooling plate on the underside. For the effective dissipation of the

resultant power loss, the box must be bolted to a metal base, e.g. the machine bed, if possible mak-

ing contact over the entire surface. A temperature-related automatic switch-off of the box can occur

if care is not taken to ensure that the power loss from the module is dissipated via the cooling plate.

A corresponding temperature error bit is then set!

Note when mounting that the overall height is increased further by the fieldbus connections. See chapter

Accessories.

3.1.3 Connector

M8 connector: X52, X53, X54, X55

Screw M8 connectors tight with a torque wrench. (e.g. ZB8801 from Beckhoff)

Torque: 0.4Nm.

B17 connector: X70, X71

Screw B17 connectors tight by hand:

Plug the cable connector into the connector on the box to the stop. Turn the cap nuts of the cable connector

clockwise by about 1/8 of a turn to the stop.

EP9224-003718 Version: 1.0

3.2 Functional earth (FE)

Functional earth via the fastening holes

The fastening holes [}17] also serve as connections for the functional earth (FE).

Make sure that the box is earthed with low impedance via both fastening screws.

FE

Fig.6: Functional earth via the fastening holes

Functional earth via the supply lines

Pins 6 of the B17 connectors marked with "FE" are not directly connected with the functional earth potential

of the fastening holes.

Connect the functional earth of the "FE" cores in accordance with the following instructions:

• If the remote station is a device with B17 connector: connect the devices with a pre-configured cable.

Order number: Beckhoff ZK7208-3031-Axxx.

• Otherwise: Earth the "PE" core with low impedance as near as possible to the remote station.

• Leave the cap nuts and housing of the B17 connectors without contact.

3.3 Power supply

EtherCAT Box modules are supplied with two electrically isolated supply voltages:

Control voltage U

S

: 24V

DC

Power is supplied to the fieldbus, the processor logic, the inputs and the sensors from the 24V

DC

control

voltage U

S

. The control voltage is electrically isolated from the fieldbus circuitry.

Peripheral voltage U

P

: 24V

DC

The peripheral voltage U

P

supplies the digital outputs; it can be brought in separately. Hence, if the load

voltage is switched off, the fieldbus function as well as the supply and function of the inputs are retained.

3.3.1 Connection

The supply and forwarding of the supply voltages takes place via two 5-pin ENP B17 hybrid connectors at

the lower end of the modules:

• X70 "IN": left B17 connector for feeding the supply voltages

• X71 "OUT": right B17 connector for routing the supply voltages

3.3.2 Status LEDs

The status of the supply voltages is signaled by two LEDs. A Status LED lights up green when the respective

supply voltage is present on the connector for the supply.

Fig.8: Status LEDs for the supply voltages

3.3.3 Conductor losses

Take into account the voltage drop on the supply line when planning a system. Avoid the voltage drop being

so high that the supply voltage at the box lies below the minimum permissible value. See Technical data

[}11].

Variations in the voltage of the power supply unit must also be taken into account.

The following graph illustrates the dependence of the voltage drop on the core cross-section, current and

cable length:
