Function Description
PROFINET PTC enables a time
delay measurement
send clock and
time between RJ45 ports and
synchronisation therefore the send cycle
, based on synchronization and time
IEEE 1588 synchronization.
PTCP uses the special
multicast MAC address:
xx-xx-xx-01-0E-CF,
xx-xx-xx =
Organizationally Unique
Identifier
PROFINET The PROFINET IO
Cyclic IO data telegrams are used to
transfer cyclically transfer I/O
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).
Hypertext HTTP is used for the
transfer communication with the
protocol CU internal Web server.
Is open in the delivery
state and can be
deactivated.
ISO-on-TCP ISO on TCP (according
protocol to RFC 1006) is used for
the message-oriented
data exchange to a
remote CPU, WinAC or
devices of other
suppliers.
Communication with ES,
HMI, etc.
Is open in the delivery
state and is always
required.
