(PROFINET)
PROFINET send clock and time synchronization, based on IEEE 1588
PTC is used to implement send clock synchronization and time syn‐
chronization between RJ45 ports, which are required for IRT opera‐
tion.
PTCP uses the special multicast MAC address:
xx-xx-xx-01-0E-CF,
xx-xx-xx = Organizationally Unique Identifier

PROFINET Cyclic IO data transfer
The PROFINET IO telegrams are used to transfer IO data cyclically
between the PROFINET IO controller and IO devices via Ethernet.

ISO on TCP
(according to
RFC 1006)
102 (4) TCP ISO-on-TCP protocol
ISO on TCP (according to RFC 1006) is used for the message-orien‐
ted data exchange to a remote CPU, WinAC or devices of other sup‐
pliers.
Communication with ES, HMI, etc. is activated in the factory setting,
and is always required.
SNMP
Simple Net‐

161 (4) UDP Simple network management protocol
SNMP enables network management data to be read out and set
(SNMP managed objects) by the SNMP manager.
It is activated in the factory setting, and is always required
