Design and function

The technology CPUs combine:

The powerful CPU 315-3 PN/DP or CPU 317-3 PN/DP and
PLCopen-compatible motion control functions and optionally fail-safe functions.

The technology CPUs are compactly built with high-speed distributed I/Os (4 digital inputs, 8 digital outputs) and two PROFIBUS and one PROFINET interface with 2-port switch:

Isochronous PROFIBUS interface DP(DRIVE) for the dynamic motion control of several coupled or single axes
MPI/DP interface for connecting other SIMATIC components, for example PG, OP, S7 controllers and distributed I/O.
For operation as a DP interface, extended networks can be set up.
CPU 317TF-2 DP: PROFIsafe via PROFIBUS for fail-safe communication

For programming the Technology CPUs you can use the STEP 7 option package S7-Technology with various ready-to-use function blocks

Applications

In combination with the PLCopen-compatible motion control blocks, the technology controllers are particularly well suited for coupled motion sequences of multiple axes.

Along with position-controlled single axis positioning, primarily complex, synchronized motion sequences are possible, e.g. gearbox synchronization, cam disk synchronization and print-mark correction. The synchronized axes can be combined to a virtual or actual master.

For path interpolations, powerful PLCopen-compatible functions are available that support various standard kinematics (SCARA, roll picker, articulated arm robot, delta-picker 2D/3D).

The isochronous PROFIBUS DP(DRIVE) permits control of the axes over a digital bus system. The two ther interfaces (PROFINET and PROFIBUS) can be used for user-friendly parameterization and commissioning of the drives from a PC/programming device.

As a result, the technology controllers can be used for a host of new applications, e.g.:

Processing/assembly lines
Throughput machines
Handling systems
Cross-arms
Gantries
Filling
Wrapping
Roll feeds
Flying shears
Carton erectors
Labeling machines
Cross cutters
Hydraulic presses
Palletizers
