EtherCAT P connection
Notice | |
Risk of damage to the device! Bring the EtherCAT/EtherCAT P system into a safe, powered down state before starting installation, disassembly or wiring of the modules! |
The feeding and forwarding of EtherCAT P is done via two EtherCAT-P-coded M8 connectors at the top of the modules:
- IN: left M8 connector with EtherCAT-P-coding for feeding EtherCAT P
- OUT: right M8 connector with EtherCAT P for forwarding the supply voltages
The pins M8 connectors carry a maximum current of 3 A.
Two LEDs display the status of the supply voltages.

Contact | Signal | Voltage | Core colors1) |
|---|---|---|---|
1 | Tx + | GNDS | yellow |
2 | Rx + | GNDP | white |
3 | Rx - | UP: Peripheral voltage, +24 VDC | blue |
4 | Tx - | US: control voltage +24 VDC | orange |

1) The core colors apply to EtherCAT P cables and ECP cables from Beckhoff.
Control voltage US 24 VDC
Power is supplied to the fieldbus, the processor logic, the inputs and the sensors from the 24 VDC control voltage US.
Auxiliary voltage Up 24 VDC
The Auxiliary voltage UP supplies the digital outputs; it can be brought in separately. If the load voltage is switched off, the fieldbus functions and the power supply and functionality of the inputs are retained.

Pay attention to the maximum permissible current! Pay attention also for the redirection of EtherCAT P, the maximum permissible current for M8 connectors of 3 A must not be exceeded! |
