Description
PTCP
Precision Trans-
parent Clock
Protocol
Not relevant
(2) Ethernet II and
IEEE 802.1Q and
Ethertype 0x8892
(PROFINET)
PROFINET
send clock and
time synchroni-
sation, based
on IEEE 1588
PTC enables a time
delay measurement
between RJ45 ports and
therefore the send cycle
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 IO

(PROFINET)
PROFINET
Cyclic IO data
transfer
The PROFINET IO tele-
grams are used to cycli-
cally transfer IO data
between the PROFINET
IO controller and IO
devices via Ethernet.
PROFINET Con-
text Manager
34964 (4) UDP PROFINET
connection less
RPC
The PROFINET context
manager provides an
endpoint mapper in
order to establish an
application relationship
(PROFINET AR).
Connection-oriented communication protocols
FTP
File transfer
protocol
21 (4) TCP Server/
incoming
FTP can be used for the
first commissioning.
FTP can be activat-
ed/deactivated using
parameter p8908.
DHCP
Dynamic Host
Configuration
Protocol
68 (4) UDP Dynamic Host
Configuration
Protocol
Is used to query an IP
address.
Is closed when deliv-
ered, and is opened
when selecting the
DHCP mode.
http
Hypertext trans-
fer protocol
80 (4) TCP Hypertext
transfer proto-
col
http is used for the
communication with the
CU-internal web server.
Is open in the delivery
state and can be deac-
tivated.
