5.2.3 External voltage supply
The external voltage supply can be used to establish EtherCAT communication for
commissioning purposes and to query the data of the digital and analog inputs.
Moreover, the external voltage supply serves to keep up EtherCAT communication in
the event of a main supply failure.
The digital inputs RFR, DI1 ... DI5 and the analog inputs can be evaluated as before.
The external voltage supply is done via the terminals 24E and GND of the terminal strip
X3.
Permissible voltage (DC) / max. current:
U = 24 V DC (20 V - 0 % ... 29 V + 0 %)
–I
max
= 400 mA
Access to parameters of a device that is disconnected from the mains is not possible.
