Depending on the device version, this includes: •...

  • Page 5: Range Of Application

    Any device modification requires prior written consent of the manufacturer. 1.2 Range of application DREHMO actuator are designed for the operation of industrial valves, e.g. globe valves, gate valves, butterfly valves and ball valves. For other applications, please contact the manufacturer. The manufacturer is not liable for any possible damage resulting from use in other than the designated applications.

  • Page 7: General Information

    General information 2 General information 2.1 General information on Profinet Profinet I/O is a communication protocol for industrial automation engineering based on Ethernet and standardised by the PROFIBUS Nutzerorganisation e.V. (PNO) worldwide. Profinet enables real time communication (RT) with short cycle times as well as acyclic communication (non RT) for configuration and diagnostics.

  • Page 8: Profinet Basic Functions

    General information Figure 1: Profinet network Configuration - Configuration - Diagnostics - Process data - Status/control - Signals - Parametrisation I/O controller (PLC) I/O supervisor (programming device) I/O device (field device) A Profinet network comprises at least one I/O controller and one or several I/O devices.
  • Page 9 General information reached. The maximum distance between two network participants is 100 metres. When using switches with fibre optic cable communication, distances can be in- creased. Only use industrial switches certified for Profinet and logically separate the Profinet based automation network from the remaining IT infrastructure. In general, hubs may not be used since this could lead to network collision.

  • Page 10: Redundancy

    General information Tree topology If you interconnect several star structures, you obtain a tree network topology. Any combination is possible. Figure 4: Tree topology I/O controller (PLC) Switch I/O device (field device) Ring topology When applying this topology, the devices and the DCS are connected in series. The major difference to line topology is that both the first and the last device are connected to the DCS.

Only one Profinet hardware is available in the DREHMO actuator, the system has two controllers. The system redundancy allows application relations (AR) between the device and several controllers. Profinet desig- nation: S2 Single NAP.

  • Page 12: Profinet Communication Cable

    General information 2.8 Profinet communication cable According to IEC 61156-6, CAT 5 cables are specified as minimum requirement for Profinet. However using CAT 5e and CAT 6 cables is recommended. For further refer- ences regarding planning an installation of Profinet networks, the PROFIBUS User Or- ganisation (PNO) (www.profibus.com) provides suitable guidelines.

  • Page 13: Profinet Conformance Classes

    General information Further notes Available Profinet recommendations, particularly planning, assembly and commission- ing guidelines of the PROFIBUS User Organisation (PNO) (www.profibus.com) must be met. 2.9 Profinet conformance classes To simply the application of Profinet, various conformance classes are defined which specify required properties of the Profinet components and ensure their interoperabil- ity by certifications.

  • Page 14: Protective Functions

    General information 2.11 Protective functions • Response monitoring (watchdog) • Access protection for inputs/outputs (sync and freeze) • Process data exchange (DATA EX) monitoring with configurable timer interval at controller • Adjustable failure behaviour at actuator in case of Profinet communication loss Port deactivation for unused network ports Unused Ethernet ports can be deactivated to prevent unauthorised and above all un- detected access to the network in the field.

  • Page 15: Commissioning

    3 Commissioning 3.1 Introduction Only few steps are required to integrate an DREHMO actuator into a Profinet environ- ment. At first, a standardised device description (GSDML file) is linked to the DCS. The device name assignment for the actuator using the DCS system tools is the next step.

  • Page 16: Mains Connection (Default)

    Commissioning 3.2 Mains connection (default) Hazardous voltage! DANGER Death or serious injury! à Work on the electrical system or equipment and electrical installation work on ac- tuators must only be carried out by skilled electricians themselves or by specially instructed personnel under the control and supervision of such an electrician and in accordance with the applicable electrical engineering rules.

  • Page 17: Communication Start

    Commissioning Note NOTICE Changing a parameter will result in renewed parametrisation and restart of the Profinet communication module. Thus, the communication for the controller will be lost for a short time. The possibly used bridge functionality of the connection sub-assembly will then be lost.
