Product overview
2.1 Applications of the S7-1500 CPUs
Performance segment of the CPU 1518-4 PN/DP MFP
The CPU can be used for the high-end area of machine and plant automation.
CPU 1518-4 PN/DP MFP can execute both STEP 7 blocks of the "usual" user program, as
well as blocks and applications that have been programmed with C/C++.
The multifunctional platform enables you to execute C/C++ code synchronously in the CPU
cycle (through the CPU function library). In addition, the multifunctional platform can run
C/C++ applications as separate applications parallel to CPU Runtime.
Figure 2-1
You create the C/C++ blocks (CPU function library for CPU Runtime) and C/C++ Runtime
applications with the "ODK 1500S Open Development Kit" (ODK).
Employing the ODK enables you to use mechanisms from high-level programming
languages (e.g. object-based) within a modern programming environment.
With ODK, you program:
● Blocks in C/C++ that can be run synchronously in the execution cycle of the CPU (CPU
function library for CPU Runtime)
● C/C++ Runtime applications running in SIMATIC S7-1500 MFP C/C++ Runtime,
independent of the STEP 7 user program
