WS0-GETH is operated in slave
mode, the IP address is assigned
from a DHCP server. After the WS0-
GETH or the DHCP server has been
restarted, a different IP address that
is unknown to the programmable
controller has been assigned to the
WS0-GETH.
Either assign a fixed IP address to the WS0-
GETH, or reserve a fixed IP address for the
WS0-GETH in the DHCP server (manual
assignment by means of the MAC address of
the WS0-GETH).
WS0-GETH/safety controller is
