Property
PROFINET IO
PROFINET interface (X1 P1
R and X1 P2 R)
PROFINET interface (X2 P1) The interface has one port. In addition to basic PROFINET
PROFINET interface (X3 P1) The interface is (typically) used to:
Operation of the CPU as
• IO controller
• I-device
PROFIBUS DP
PROFIBUS interface (X4)
Operation of the CPU as a
DP master
Accessories

CPU 1518-4 PN/DP MFP (6ES7518-4AX00-1AB0)
Equipment Manual, 11/2022, A5E40882737-AC
Description
The interface has two ports. In addition to basic
PROFINET functionality, it also supports PROFINET IO RT
(real time) and IRT (isochronous real time).
functionality, it also supports PROFINET IO RT (real time).
• Link development tools for C/C++ applications
• Connect the TIA Portal to the development of STEP 7
applications
• Communicate to the "outside world" from C/C++
Runtime
• Communicate internally between C/C++ and CPU
Runtime (via virtual network)
• IO controller:
As an IO controller, the CPU addresses the connected
IO devices
• I‑device
As an I‑device (intelligent IO device), the CPU is
assigned to a higher-level IO controller and is used as
an intelligent pre-processing unit for subroutines
The interface is used for connecting to a PROFIBUS net­
work.
In the role as a DP master, the CPU addresses the connec­
ted DP slaves. It is not possible for the CPU to take the
role of a DP slave.
