Automation platform combines control and PC functions
Siemens has announced a multifunction platform that combines control and PC functions in a single, space-saving and easier-to-program device. The Simatic CPU 1518(F)-4 PN/DP MFP controller handles tasks that had previously been outsourced to PCs – such as model-based and high-level language programming, and database applications.
The platform integrates high-level language functions and allows stand-alone applications to be created and re-used easily. Existing C/C++ algorithms can continue to be used. Exchanging data between PCs and controllers, which previously had to be programmed, has been simplified.
The configuration has been standardised and the combined package is said to be more resilient, running on one piece of hardware with a stable embedded operating system. Users can program controller-independent C/C++ applications – such as protocol converters and database applications – with standard programming tools, such as Eclipse. These run as standalone C/C++ applications in parallel with the control program on the multifunction platform.
The need for extra PC hardware is eliminated. Users can also use model-based development tools, such as Matlab Simulink, and transfer complex functions to the new platform, which can be used with TIA Portal V15 or higher.
Siemens has also expanded its range of technology CPUs with two new models for mid-range motion control tasks. The 1516T-3 PN/DP CPU and the 1516TF-3 PN/DP failsafe CPU combine standard, safety, and motion control functions – such as gearing and camming – in one device. Mid-range motion control tasks can be implemented easily in conjunction with the Sinamics V90 PN and S210 servodrives.
The motion control functions of Siemens’ Simatic S7-1500 CPUs have also been extended to include the control of 2D to 4D kinematics, making additional handling applications possible, such as pick-and-place, Cartesian, delta picker and Scara robots.
Siemens’ scalable Simatic family of controllers now comprises basic, advanced, distributed and software models, all of which share the same functions. The S7-1200 basic controllers are used for compact automation applications, the S7-1500 advanced controllers for complex tasks, the ET 200SP distributed controllers are suitable for distributed applications and the software controllers for PC-based applications.
