• Communication:
– Interfaces
20
CPU 1518-4 PN/DP has four interfaces. Three interfaces for PROFINET and one for
PROFIBUS.
The first PROFINET interface (X1 P1, X1 P2) has two ports. In addition to PROFINET
basic functionality, it also supports PROFINET IO RT (real-time) and IRT (isochronous
real-time). PROFINET IO communication or real-time settings can be configured.
Even with a send clock of 125 µs, IO communication and standard communication is
possible via one cable.
Port 1 and port 2 can also be used as ring ports for the configuration of redundant ring
structures in Ethernet.
The second PROFINET interface (X2 P1) has one port. In addition to basic PROFINET
functionality, its also supports PROFINET IO RT (real-time). The basic functionality of
PROFINET supports HMI communication, communication with the configuration
