Description

PROFINET (Process Field Network) is an open standard for an industrial real-time Ethernet system in automation. It is managed by the user organisation PI (PROFIBUS&PROFINET International as the umbrella organisation of the PROFIBUS user organization PNO) and is considered the successor of PROFIBUS. PROFINET uses the IEEE 802.3 (Standard Ethernet) based Profinet RT protocol for cyclical real-time I/O communication and UDP/IP for acyclic services.

The fully integrated CODESYS PROFINET solution offers a uniform configurator for the various variants of the PROFINET Controller communication stack:

  • CODESYS PROFINET Controller (IEC)
    Protocol Stack in the form of a CODESYS libraries (in IEC 61131-3 code) works on standard network interfaces.
    For CODESYS Control RTE, special Ethernet drivers are available for very high transmission performance (see requirements).
    The network interface is not used exclusively, it is still available for other TCP/IP applications (e.g. CODESYS Visualisation, Web Browser).

CODESYS PROFINET Configurator

  • Configurator for PROFINET Controller settings
  • Configuration of slaves (single AR to PROFINET field device) with communication settings
  • Configuration of device-specific settings, input and output mapping
  • Status page with detailed view of the currently attached diagnosis and received alarms
  • Scan dialog with device import function, online/offline comparison, I&M data
  • Topology Configurator (for device replacement, IRT planning)
  • Media Redundancy (MRP) Configurator

Profinet stack (IEC)

The CODESYS PROFINET Controller Stack can in principle run on any standard Ethernet hardware (see Prerequisites for conditions and limitations). This Ethernet adapter can still be used for other services such as CODESYS communication (with the IDE), web server, or other CODESYS fieldbuses (except EtherCAT). The CODESYS Runtime and the operating system (e.g. Firewall) must be configured correctly. For details see CODESYS Online Help / Fieldbus Support (https://help.codesys.com/)

CODESYS CONTROLLER Device (IEC) and Dual-Port Interface:
With standard Ethernet adapter hardware, only single port devices are possible, i.e. every PROFINET controller can only manage one port. (The system itself can have more than one Ethernet adapter, for example a PROFINET device could run on it).
A dual-port device (e.g. for MRP or a so-called ‘daisy chain’) can be implemented with special dual port (bridge) Ethernet chipsets, but this requires adjustments to the runtime system by the OEM.
Performance CODESYS PROFINET Controller (IEC):
The IO power, i.e. the possible transmitted Ethernet frames / ms, is very different depending on the platform and ranges from excellent (CODESYS Control RTE) to rather weak (out of the box Win CE).
It depends almost exclusively on the SysEthernet implementation of the CODESYS Runtime.
Of course, a system that only provides 8 frames / ms can also control 32 field devices, for example – but only with an interval of 4 ms.

Requirements

Programming system

CODESYS Development System V3.5.17.0 or higher

Runtime system

CODESYS Control V3.5.4.0 or higher

Supported platforms/devices

CODESYS runtime system with these components

* SysEthernet

* SysSocket

Note: Use the Device Reader project to determine the functions supported by the controller. Device Reader is available free of charge from the CODESYS Store.

Additional requirements

Technical requirements

* Ethernet adapter (for control RTE with Intel or Realtek chipset)

Legal requirements

Any device that is sold as a PROFINET controller or device to an end user must be certified by a PI testing laboratory.

Details on the certification can be found here:

www.profibus.com/products/product-certification/

Limitations

Certification currently only possible for

* Control RTE > V3.5.18.30

* Linux based Runtimes > V3.5.17.30

Licensing

Single device license: The license can be used on the controller on which the CODESYS runtime system is installed.


The license activation is done on a software-based license container (soft container), which is permanently bound to the control system. Alternatively, the license can be stored on a CODESYS key (USB dongle). By redefining the CODESYS Key, the license can be used on another controller.

Required accessories

Optional: CODESYS Key
