Smart field distributor – SIMATIC Compact Field Unit

  • Entry
  • Associated product(s)
The SIMATIC Compact Field Unit is released for delivery.

Digitalization is an important catalyst for the process industry. When developing SIMATIC PCS 7 V9.0 – the new version of the proven SIMATIC PCS 7 process control system – the emphasis was placed on a forward-looking approach to the possibilities of digitalization, down to the field level. For that reason, the system solution has been extended by particularly powerful and compact hardware products that are compatible with PROFINET, the world's leading Industrial Ethernet standard, that free up resources for enhanced plant planning and operation.
With the new SIMATIC Compact Field Unit (CFU), we are reinterpreting the conventional approach to field device connection. This means that you benefit from greater flexibility and ease of use, together with the highest availability, allowing you to efficiently transfer your trusted system concept into the digital world.

Today's challenges in field device connection

  • High overhead for device integration and replacement
  • Complicated, error-prone wiring and marshalling over several levels, making the hardware FAT very complex
  • Very long copper cable spanning and a lot of clamping points in the field
  • A myriad of individual control cabinets
  • Large numbers of different components and protocols necessitate costly spare parts inventories and training sessions
  • High planning and documentation costs

1. SIMATIC CFU – the response to these requirements


How it works



Field device connection with previous technology (left) and with SIMATIC CFU (right)

The new SIMATIC Compact Field Unit (CFU) is a real game-changer in field device connection and offers you entirely new prospects regarding simplicity and flexibility. The compact field distributor is installed at the process level and is connected via PROFINET directly to the process control system to form the foundation for digitalization in the field. Utilization of digital fieldbus communication simplifies device interfacing considerably compared to conventional 4 - 20 mA engineering. 

More versatility due to consistent decentralization

Due to the distributed installation of the SIMATIC CFU, classic control cabinets are no longer required and you can benefit from the considerable savings in cabling and the number of terminal points as well as the reduction of overhead for planning and documentation. The high granularity (16 I/O per SIMATIC CFU) enables flexible assignment to the higher-level controllers.

Function





The SIMATIC CFU was specifically designed to meet the requirements of the process industry in the Industrie 4.0 environment (in this example: SIMATIC CFU in a standard aluminum field enclosure).

System interfacing via Industrial Ethernet standard

  • Redundant PROFINET connection (S2) for the highest degree of availability
  • Connection versatility with PROFINET
  • BusAdapter (for example electrical, optical or mixed)

Ready for distributed use

  • Installation in hazardous areas up to zone 2/22 (with conformal housing)

  • Extended temperature range from -40 to +70 °C

  • Conformal coating

  • Use at altitudes up to 4000 meters

  • Enhanced interference immunity according to NAMUR NE21       

  • Optional: Aluminum housing for direct field use up to zone 2/22

2. Overview of components

SIMATIC CFU PA-Edition



SIMATIC CFU PA: in this case with Bus Adapter, PROFINET bus cable and push-in terminals


2.1 SIMATIC CFU PA Edition

Plug-and-produce simplicity
Digitalization requires a digital infrastructure facilitating integrated digital communication down to the field level. This can be built up using the standard, tried and tested PROFIBUS PA. This is integrated into the PA Edition of the SIMATIC CFU, thus combining ruggedness and easy handling with all the advantages of the PROFINET standard based on Industrial Ethernet. Connected devices are automatically addressed. The device is integrated via standardized communication profiles.

This completely innovative implementation of the PROFIBUS PA concept makes it possible to combine the simplicity of a point-to-point wiring system with the scalability of digital PROFIBUS PA fieldbus communication. As with digital field devices, it is not necessary to know whether the discrete field device is a sensor or actuator prior to connection. This can be conveniently configured afterwards via software.

Combination of digital fieldbus and discrete I/O

  • 8 × digital fieldbus (PROFIBUS PA)
  • 8 × digital inputs/outputs, freely configurable   

Easy to use

  • Automatic addressing of PROFIBUS PA field devices
  • System-supported detection and integration of PROFIBUS PA field devices into the process control system
    • Utilization of standardized PA profiles
    • Commissioning, device exchange and maintenance wizards
  • Implementation of diagnostic messages according to NAMUR NE 107
  • 35 mm standard rail mounting

Features

  • 16 x I/O Channels

  • PROFINET interface V2.3 (RT)

  • Use of PROFINET BusAdapter

  • Media redundancy (MRP)

  • PROFINET system redundancy (S2)

  • Configuration in RUN (CiR)

  • Process interfaces:

    • 8 x PROFIBUS PA (with plug-and-produce)

    • 8 x freely configurable DIQ

  • Installation up to Ex zone 2

  • Temperature range from -40 to +70 °C

  • Conformal coating

  • 35 mm standard rail mounting

  • Available in an aluminum housing          


2.2 SIMATIC CFU DIQ-Edition New with V1.2.0!

Individual, customer-specific solutions and flexible system/plant extensions are requirements that are becoming increasingly important due to digitalization in the process industry. With 16 freely configurable digital IO channels, the SIMATIC CFU DIQ Edition offers a solution for the growing demands for the decentralized peripherals. In addition, the SIMATIC CFU has expansion functions that can be optionally parameterized.

Two additional operating modes can be activated for selected digital inputs. Operating mode "counter" and operating mode "frequency measurement" with a cut-off frequency of 1 kHz.

An actuator shutdown can be set for the digital outputs. The SIMATIC CFUs control gear switch-off uses a monitoring channel (DI channel) to quickly set all digital outputs to low digital levels.

Feature

  • 16 x I/O Channels
    • 16x free configurable digital In-/Outputs

    • 2x optional Counter functionality or frequency measurement

  • PROFINET interface V2.3 (RT)
  • Use of PROFINET BusAdapter
  • Media redundancy (MRP)
  • PROFINET system redundancy (S2)
