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)

EtherCAT Box - Introduction

2 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

2-port EtherCATP junction
The 2-port EtherCAT P junction enables configuration of EtherCAT P topologies from an EtherCAT system. A modular EtherCAT P star can be realised by using several EP1312-0001 in series. Individual devices or complete EtherCAT P strands can be connected at the junction ports. EtherCAT P branches are connected via screw type, shielded EtherCAT-P-coded M8 sockets. The state of the EtherCAT P line is indicated by the Link/Activity LEDs. The Run LED indicates the status of the EP1312-0001.
