Manual, 12/2017, A5E40882737-AA
Description
CPU 1518-4 PN/DPMFP can execute both STEP 7
blocks as well as blocks and applications programmed
with C/C++, C#, VB.Net (CPU function library) in the
user program.
The multifunctional platform enables you to execute
C/C++ code (CPU function library for the real-time
environment) synchronously in the CPU cycle.
The CPU function library can continue to be used
asynchronously in the CPU cycle for Windows envi-
ronments (C/C++, C#, VB.Net).
In addition, the multifunctional platform can run C/C++
applications (C/C++ Runtime Application) parallel to the
CPU cycle.
You create the CPU function library for the realtime and
Windows environment, as well as C/C++ Runtime Ap-
plications 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.
You can use Target 1500S for Simulink and ODK
1500S to create C/C++ code for the realtime environ-
ment for your complex open and closed-loop algo-
rithms.
The system automatically generates the alarms for
system diagnostics and outputs the alarms via a pro-
gramming device/PC, HMI device, the web server or
the integrated display. System diagnostics information
is also available when the CPU is in STOP mode.
The web server allows you to access CPU data over a
network. Evaluations, diagnostics, and modifications
are thus possible over long distances. Monitoring and
evaluation is possible without STEP 7; only a web
browser is required. Make sure that you take appropri-
ate measures (e.g. limiting network access, using fire-
walls) to protect the CPU from being compromised.
