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)
YY - year of production
FF - firmware version
HH - hardware version
Example with D no. 29 10 02 01:
29 - week of production 29
10 - year of production 2010
02 - firmware version 02
01 - hardware version 01

EtherCATP
EtherCATP supplements the EtherCAT technology with a process in which communication and supply
voltages are transmitted on a common line. All EtherCAT properties are retained with this process.
Two supply voltages are transmitted per EtherCATP line. The supply voltages are electrically isolated from
each other and can therefore be switched individually. The nominal supply voltage for both is 24VDC.
EtherCATP uses the same cable structure as EtherCAT: a 4-core Ethernet cable with M8 connectors. The
connectors are mechanically coded so that EtherCAT connectors and EtherCATP connectors cannot be
interchanged.
EtherCATP Box modules
EtherCATP Box modules are EtherCATP slaves with degree of protection IP67. They are designed for
operation in wet, dirty or dusty industrial environments.
EtherCAT basics
A detailed description of the EtherCAT system can be found in the EtherCAT system documentation.

3.2.1 Introduction
4-channel digital input 24 V DC, 3.0 ms
The EPP1004-0061 EtherCAT P Box with digital inputs acquires the binary control signals from the process
level and transmits them, in an electrically isolated form, to the controller. The state of the signals is indicated
by light emitting diodes. The signals are connected via M8 screw type connectors.
The EtherCAT P Box modules are characterised by their small and space-saving form factor.

3.4.3 Scope of supply
Make sure that the following components are included in the scope of delivery:
• 1x EPP10x8-0002 EtherCAT P Box
• 2x protective cap for EtherCATP socket, M8, red (pre-assembled)
• 10x labels, blank (1 strip of 10)
Pre-assembled protective caps do not ensure IP67 protection
Protective caps are pre-assembled at the factory to protect connectors during transport. They may
not be tight enough to ensure IP67 protection.
Ensure that the protective caps are correctly seated to ensure IP67 protection.
