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, field­configurable 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.

2.2 EP9214 - Introduction

Fig.4: EP9214
Power distribution for EtherCAT Box (24VDC)
The EP9214-0023 enables connection of four power supply branches. In each branch the current consumption for the control voltage US and the peripheral voltage UP is monitored, limited, and, if necessary, switched off.
The power distribution is supplied via a 7/8" connector with up to 16A (per voltage supply US/UP). Several modules can be configured in a cascade arrangement. In the event of a short-circuit in one of the four outputs, the affected output is switched off. The supply for the other branches remains active. The switch-off and control is done in such a way that the input voltage does not fall below 21V or other modules are going down, caused by undervoltage.
During startup consumers with large capacities can be added without problem.
The master can read diagnostic messages from the individual channels via the EtherCAT interface. Independent switching of individual consumer branches is also possible via the EtherCAT master.
In delivery state the eight outputs of the box (4 times Us, 4 times Up) are activated to enable operation without EtherCAT.
After an error caused the switch off of a channel, this channel remains switched of when you try to switch it on again and has to be set back actively by the EtherCAT master or a hardware reset at the box (lower M8 socket).

Product overview
Fig.5: EP9224
Power distribution for EtherCAT Box (24VDC) with data logging
The EP9224-0023 enables connection of four power supply branches. In each branch the current consumption for the control voltage US and the peripheral voltage UP is monitored, limited, and, if necessary, switched off.
The power distribution is supplied via a 7/8" connector with up to 16 A (per voltage supply US/UP). Several modules can be configured in a cascade arrangement. In the event of a short-circuit in one of the four outputs, the affected output is switched off. The supply for the other branches remains active. The switch-off and control is done in such a way that the input voltage does not fall below 21 V or other modules are going down, caused by undervoltage.
During startup consumers with large capacities can be added without problem.
The master can read diagnostic messages from the individual channels via the EtherCAT interface. Independent switching of individual consumer branches is also possible via the EtherCAT master.
In delivery state the eight outputs of the box (4 times Us, 4 times Up) are activated to enable operation without EtherCAT.
After an error caused the switch off of a channel, this channel remains switched of when you try to switch it on again and has to be set back actively by the EtherCAT master or a hardware reset at the box (lower M8 socket).
Additional to this basic functionality that is also provided by EP9214, the EP9224 displays the voltage values of PowerIn supply and all current values of inputs and outputs within the process data.
The box has got an internal log file, that is writing the system values continuously into a ring buffer. This data logging has to be activated at the startup. In error case it is stopped, so a history of the system parameters from before the error case can be read out. This enables a much quicker error localization.

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 cat­alogue for connector sets and protective caps)!
Cooling plate
The EP9214 module has a cooling plate on the underside. For the effective dissipation of
Note
Note when mounting that the overall height is increased further by the fieldbus connections. See the Accessories section
the resultant power loss, the box must be bolted to a metal base, e.g. the machine bed, if possible making 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!

3.3.3 Power cable conductor losses M8

The ZK2020-xxxx-yyyy power cables should not exceed the total length of 15m at 4A (with continuation). When planning the cabling, note that at 24V nominal voltage, the functionality of the module can no longer be assured if the voltage drop reaches 6V. Variations in the output voltage from the power supply unit must also be taken into account.

3.3.5 Conductor losses 7/8"

In the case of the power cables ZK2030-xxxx-yyy, a total length of 15m should not be exceeded at 16A. When wiring, note that with a rated voltage of 24V the function of the modules can no longer be guaranteed from a voltage drop of 6V. Variations in the output voltage from the power supply unit must also be taken into account.

Alternatively, larger cable cross-section can be used, e.g. 2.5mm2.

3.3.6 Power outputs

The supply voltages are output via four 4-pole M8 sockets in the lower third of the modules (1, 2, 3 and 4).

Mounting and cabling
Control voltage Us: 24V
DC
Power is supplied to the fieldbus, the processor logic, the inputs and the sensors from the control voltage Us (24VDC). The control voltage is electrically isolated from the fieldbus circuitry.
Peripheral voltage Up: 24V
DC
The peripheral voltage Up (24VDC) 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.
Electrical isolation
The grounds of the control voltage (GNDs) and peripheral voltage (GNDp) are electrically isolated from each other in order to ensure the electrical isolation of the peripheral devices on Up from the control voltage.
The electrical isolation can be nullified
If you connect digital and analog EtherCAT Box Modules directly to one another via four­pole power lines, then there may no longer be any electrical isolation due to the connected

Mounting and cabling
For connecting EtherCAT devices, only use shielded Ethernet cables with a minimum specification of
category5 (CAT5) according to EN50173 or ISO/IEC11801.
Wiring recommendations
Detailed recommendations for EtherCAT cabling can be found in the documentation "De-
Note
EtherCAT uses four cable wires for signal transmission. Due to automatic cable detection (auto-crossing) symmetric (1:1) or cross-over cables can be used between EtherCAT devices from Beckhoff.
