Siemens announces Simatic CPU 317TF-2DP motion controller
October 7, 2010 - Siemens announced the Simatic CPU 317TF-2DP controller that combines motion control, safety and standard tasks in a single device.

The Simatic CPU 317TF-2DP controller unites a series of important features that all go together in one device to reduce the wiring, coding and the implementation times. It also benefits users by saving space on the shop floor and reducing overall total cost of ownership.

Possible applications for the new device range from controlled single-axis positioning to complex, synchronized sequences of motion, such as geared synchronous motion, curve synchronization or print mark correction. The synchronous axes can be coupled to a virtual master or a real master. For safety-oriented applications, the controller fulfills the rigorous requirements of all the relevant standards, including EN 954-1 up to Cat. 4, IEC 62061 up to SIL 3 and EN ISO 13849-1 up to PL e.

For Siemens PLC users, the Step 7 option package S7-Technology is available to simplify engineering and commissioning. The Step 7 option package, supporting simultaneous processing of up to 64 technology objects, is available to meet engineering requirements for programming and commissioning of all functions. For specific fail-safe applications, the Step 7 option package Distributed Safety offers a set of pre-configured library blocks, including emergency stop, two-hand control, muting and door monitoring. No external safety hardware is required for costly safety precautions at the machine, saving valuable space in the control cabinet.

Centralized and distributed fail-safe I/O and fail-safe drives according to PROFIsafe, the fail-safe communication standard, can be connected to the Simatic CPU 317TF-2DP. The drive safety functions SBC, SLS, SSM, SOS, SS1, SS2 and STO according to PROFIsafe can be used in addition to the familiar safety functions.

PROFIsafe both enhances this controller’s capabilities and value while further simplifying commissioning. In particular, PROFIsafe requires less wiring than other controllers available in the market, making it quicker and easier to set up while reducing the risk of errors through the commissioning process.


This device is the latest solution in its totally integrated automation portfolio that integrates and combines devices for the plant floor environment, further reducing footprints and improving overall efficiencies.
