EtherCAT Box

2 EtherCAT Box

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.

3.1 Introduction

Fig.4: EP3204-0002

EtherCAT Box with four analog inputs for PT100 (RTD)

The EP3204 EtherCAT Box with analog inputs enables direct connection of resistance sensors. The module circuit can operate sensors with 2-, 3- and 4-wire technology. Linearisation over the full temperature range is realized with the aid of a microprocessor. The temperature range can be selected freely. The module can also be used for simple resistance measurement, with the output in ohms. The module's standard settings are: Resolution 0.1°C in the temperature range of PT100 sensors in 4-wire connection. Sensor malfunctions such as broken wires are indicated by error LEDs.

The module is quite versatile, but the default values are selected in such a way that in most cases it is not necessary to perform configuration. The input filter and associated conversion times can be set within a wide range, and several data output formats may be chosen. The inputs can, if required, be scaled differently, and automatic limit monitoring is also available. EtherCAT is used for parameterization purposes.

EtherCAT Box with four analog inputs for thermocouples

The EP3314 EtherCAT Box with analog inputs enables direct connection of four thermocouples. The module circuit can operate thermocouple sensors in a 2-wire configuration. Linearisation over the full temperature range is realized with the aid of a microprocessor. The temperature range can be selected freely. The error LEDs indicate a broken wire. Compensation for the cold junction is made through a temperature measurement in the connecting plugs. This means that standard extension leads can be connected. The EP3314 also enables millivolt measurement.

5.2.1 Supply voltages

The EtherCAT Box is supplied with two supply voltages.

Mounting and connection

• Control voltage U

• Peripheral voltage U

EP3314: The ground potentials of the supply voltages are linked.

Redirection of the supply voltages

The IN and OUT power connections are bridged in the module (not IP204x-Bxxx and IE204x). The supply voltages US and UP can thus easily be transferred from EtherCATBox to EtherCATBox.

NOTE

Pay attention to the maximum permissible current!

Pay attention also for the redirection of the supply voltages US and UP, the maximum permissible current for M8 connectors of 4A must not be exceeded!

5.2.1.3 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 nominal voltage.

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

5.2.2.3 Cables

For connecting EtherCAT devices only shielded Ethernet cables that meet the requirements of at least category5 (CAT5) according to EN50173 or ISO/IEC11801 should be used.

EtherCAT uses four wires for signal transmission. Thanks to automatic line detection ("Auto MDI-X"), both symmetrical (1:1) or cross-over cables can be used between Beckhoff EtherCAT.

5.2.3 Signal connection

5.2.3.1 EP3204: Pt100 (RTD)

The advantage of four-wire technique is that the error resulting from the cable and contacts is included in the measurement and cancelled out. In the 3-wire technique, the line resistance to the resistance sensor is measured in one direction only, and is multiplied by two. This requires the outward and return lines to have approximately the same ohmic resistance. An error is present in the two-wire technique; temperature differences and cable cross-sections can make this error vary considerably.

Fig.15: Signal connection - PT100 (RTD)

Supply voltage

US - supplies the electronics for the fieldbus and for the sensor. It is electrically isolated from UP.

UP - Is not required for the function of the module, and does not have to be fed in.

NOTE

Redirection of the supply voltages

If you use UP to pass the power on, and you connect a module in which US and UP are not electrically isolated (e.g. any digital module) then the electrical isolation is removed by the downstream connection.

EP3204 and EP3314 27Version: 2.2

Mounting and connection

5.2.3.2 EP3314: Thermocouples

The temperature compensation is fed to the outside of the modules. This means that in the connector the temperature compensation is measured directly at the connection point. This allows the temperature to be measured with significantly better accuracy. Beckhoff offer a connector (ZS2000-3712) for this. The temperature compensation can also be carried out at a location other than the Fieldbus Box. You must then wire a PT1000 between pins 1 and 3. The longer the cables you choose to use, the larger is the measurement error caused by the length of the conductor, conductor losses and interference.

Supply voltage

US - supplies the electronics for the fieldbus and for the sensor. It is electrically isolated from UP.

UP - Is not required for the function of the module, and does not have to be fed in.
