Communication Details with E-727
EtherCAT communication can be established when the power-on/reboot sequence of the E-727 is
finished (Power LED is continuously lit). The power-on/reboot sequence for E-727 models with
EtherCAT interface takes about 30 seconds.
The PC interfaces of the E-727 (TCP/IP, USB) are disabled when EtherCAT communication is
running (i.e., when E-727 is in OPERATIONAL communication state). They will be enabled again
after a delay of 100 ms when the E-727 has left the OPERATIONAL communication state.
The RUN LED of the E-727 indicates the current state of the EtherCAT communication state
machine. For details, see the description in “Product View” (p. 14).
INFORMATION
EtherCAT communication must not run when you attempt to change parameter settings of the E-
727 (p. 185) or update the firmware of the E-727 (p. 204).
