Siemens Simatic CPU 317TF-2DP controller

The Simatic CPU 317TF-2DP controller from Siemens implements motion control, safety and standard tasks in one device. The controller utilises PLCopen-compatible motion control blocks and is suitable for coupled motion sequences of multiple axes.

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

For all functions the Step 7 option package S7-Technology is available for engineering purposes for programming and commissioning. It permits simultaneous processing of up to 64 technology objects.

For failsafe applications, the Step 7 option package Distributed Safety offers preconfigured, TÜV-certified library blocks for functions such as emergency stop, two-handed control, muting and door monitoring. No external safety hardware is required for safety precautions at the machine, thus less space is required in the control cabinet.

Centralised and distributed failsafe I/O and failsafe drives according to PROFIsafe 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.

Compared to conventional technology, the use of PROFIsafe technology results in reduced wiring overhead, reduces the risk of errors when wiring, and increases flexibility during commissioning.
