Failsafe Technology CPU 317TF-3 PN/DP

The SIMATIC CPU 317TF-3 PN/DP is a controller that enables motion control, standard and safety-related applications to be processed in one single device. Thanks to the integration of Safety Integrated, the controller 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 for safety-related applications.

The STEP 7 option package Distributed Safety features pre-programmed TÜV-certified library blocks for fail-safe applications, e.g. for Emergency Stop, two-hand control, muting and door monitoring.

The technology controller provides for 64 technology objects and incorporates both a large program memory and a large quantity framework for sophisticated applications.

  • For cross-industry automation tasks in series machines, special machines and plant construction

  • Conformity with the relevant standards: EN 954-1 (up to Cat. 4), IEC 62061 (up to SIL 3), EN ISO 13849-1 (up to PL e)

  • Direct execution of fail-safe functions related to the drives

  • With PROFINET and PROFIBUS DP interface

  • Connection of drives via PROFIBUS DP(DRIVE)

  • PROFIsafe via PROFINET or PROFIBUS

  • High processing capacity for binary and floating-point arithmetics

  • Suitable for large I/O configurations

  • Suitable for distributed I/O configurations

  • Optionally supports the use of SIMATIC Engineering Tools

  • For failsafe communication, the controller uses PROFIBUS DP and PROFINET with the PROFIsafe protocol

  • Failsafe functions from the drives can be processed directly

  • 1.5 MB work memory


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
