Description
PTCP
Precision
Transparent
Clock Protocol
Not relevant (2) Ethertype
0x8892
(PROFINET)
PROFINET
send clock and time syn-
chronization, based on
IEEE 1588
PTCP provides a time delay measure-
ment between RJ45 ports and thus send
clock synchronization and time synchro-
nization.
PTCP uses standard-compliant Multicast
MAC addresses.
PROFINET IO
data
Not relevant (2) Ethertype
0x8892
(PROFINET)
PROFINET Cyclic IO data
transfer
The PROFINET IO frames are used to
transmit IO data cyclically between
PROFINET IO controller and IO devices
via Ethernet.
PROFINET
Context Man-
ager
34964 (4) UDP PROFINET connection less
RPC
The PROFINET Context Manager pro-
vides an endpoint mapper in order to
establish an application relation
(PROFINET AR).
Connection-oriented communications protocols
SMTP
Simple mail
transfer proto-
col
25 (4) TCP Simple mail transfer proto-
col
SMTP is used for sending e-mails.
SMTPS
(SMTP over
TLS)
465 (4) TCP Secure SMTP SMTP is used for sending e-mails over
secure connections.
SMTP with
STARTTLS
25
587
(4) TCP Simple mail transfer proto-
col with the SMTP com-
mand "STARTTLS"
SMTP with STARTTLS is used for send-
ing e-mails over secure connections.
HTTP
Hypertext
transfer proto-
col
80 (4) TCP Hypertext transfer protocol HTTP is used for communication with
the CPU-internal web server.
ISO-on-TCP
(according to
RFC 1006)
102 (4) TCP ISO-on-TCP protocol ISO-on-TCP (according to RFC 1006) is
used for message-oriented data ex-
change with remote CPU or software
controller.
S7 communication with ES, HMI, OPC
server, etc.
NTP
Network time
protocol
123 (4) UDP Network time protocol NTP is used for synchronization of the
CPU system time with the time of an
NTP server.
SNMP
Simple net-
work man-
agement
protocol
161
162 (trap)
(4) UDP Simple network manage-
ment protocol
SNMP is used for reading and setting of
network management data (SNMP
managed Objects) by the SNMP Man-
ager.
HTTPS
Secure Hyper-
text transfer
protocol
443 (4) TCP Secure Hypertext transfer
protocol
HTTPS is used for communication with
the CPU-internal web server via Secure
Socket Layer (SSL).
