Function Description
PROFINET PTC enables a time
delay measurement
send clock and
time synchroni- between RJ45 ports and
sation, based therefore the send cycle
on IEEE 1588 synchronization and time
synchronization.
PTCP uses the special
multicast MAC address:
xx-xx-xx-01-0E-CF,
xx-xx-xx = Organization-
ally Unique Identifier
PROFINET The PROFINET IO tele-
Cyclic IO data grams are used to cycli-
transfer cally transfer IO data
between the PROFINET
IO controller and IO
devices via Ethernet.
PROFINET The PROFINET context
connection less manager provides an
RPC endpoint mapper in
order to establish an
application relationship
(PROFINET AR).
Server/ FTP can be used for the
incoming first commissioning.
FTP can be activat-
ed/deactivated using
parameter p8908.
Dynamic Host Is used to query an IP
Configuration address.
Protocol
Is closed when deliv-
ered, and is opened
when selecting the
DHCP mode.
Hypertext http is used for the
transfer proto- communication with the
col CU-internal web server.
Is open in the delivery
state and can be deac-
tivated.
