Technology CPUs S7-315T-2DP and 317T-2DP
Applications
The advantages at a glance
The S7-300 technology CPUs 315T-2 DP and 317T-2 DP provide the full functionality of the powerful standard CPUs with integrated technology functions.
The technology CPUs combine
- SIMATIC CPU 315-2 DP / 317-2 DP with
- PLCopen-compatible motion control functions.
The technology CPUs are compactly built with high-speed distributed I/Os (4 digital inputs, 8 digital outputs) and two PROFIBUS DP interfaces:
- 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.

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.
The isochronous PROFIBUS permits control of the axes over a digital bus system. The second PROFIBUS DP interface 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 |
|
Wrapping |
|
Throughput machines |
|
Roll feeds |
|
Palleters |
|
Flying shears |
|
Cross-arms |
|
Carton erectors |
|
Simple gantries (with simple interpolation on
basis of cam disk synchronization) |
|
Labeling machines |
|
