CPU 315T-2 DP for plants with medium to high requirements on program scope and distributed configuration using PROFIBUS DP, which also require regulated motion control of up to 8 axes  

CPU 317T-2 DP for plants with high requirements on program scope and distributed configuration using PROFIBUS DP, which must handle simultaneous motion control tasks

SIMATIC CPU 317TF-2DP offers safety functions beside the functions and performance of the SIMATIC CPU 317T-2DP and meets the stringent safety requirements of the relevant standards, i.e. EN 954-1 up to Cat. 4, IEC 62061 up to SIL 3 and EN ISO 13849-1 up to PL e 

High economic efficiency and flexibility by implementing your PLC, motion control and technological demands
- Scaleable PLC performance (CPU 315T/CPU 317T/CPU 317TF)
- Integration of technology/motion control and optionally fail-safe functions in a SIMATIC CPU 
- Centralised/decentralised expandability for a wide variety of tasks provided by the use 
  of the comprehensive SIMATIC product line  

Cost savings by means of the absolute simple and fast engineering:
- From drives to motion control to PLC 
- all with STEP 7 - Reduced programming costs/optimised time-to-market by the reuse of
   existing S7 programs
- PLCopen-certified motion control functions facilitate engineering and service
- Option package Disrtibuted Safety with fail-safe TUEV certified function blocks for safety-related applications with CPU 317TF 
- Reduced training effort for commissioning and service people thanks to full programming 
  in all SIMATIC languages
