Product overview
2.3 Properties
Properties
CPU 1518-4 PN/DP ODK has the following technical properties:
● C/C++ applications
Their C/C++ applications are generated via the SIMATIC S7-1500 ODK. They are loaded
with the TIA Portal and the Web server. With the SIMATIC S7-1500 ODK you program
functions from which you can launch the STEP 7 user program.
You can find the description of the ODK application in the
Open Development Kit 1500S
However, only the part covering the real-time functionality applies to the CPU 1518-4
PN/DP ODK.
● Communication:
– Interfaces
20
CPU 1518-4 PN/DP ODK has four interfaces. Three interfaces for PROFINET and one
for PROFIBUS.
The 1st 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 2nd PROFINET interface (X2 P1) has one port. In addition to PROFINET basic
functionality, its also supports PROFINET IO RT (real-time). The basic functionality of
PROFINET supports HMI communication, communication with the configuration
system, communication with a higher-level network (backbone, router, Internet) and
communication with another machine or automation cell.
The 3rd PROFINET interface (X3 P1) has one port and supports PROFINET basic
functionality, i.e. no IO controller / IO device role. The basic functionality of PROFINET
supports HMI communication, communication with the configuration system,
communication with a higher-level network (backbone, router, Internet) and
communication with another machine or automation cell. The 3rd PROFINET interface
supports a transmission rate of 1000 Mbps as of firmware version V1.7.
Note
IP subnets
The IP subnets of the three interfaces must be different. This means that the IP
addresses of the three interfaces must differ from each other in the subnets.
