Definitions

  • the invention relates to a process automation system comprising a device
  • management system in particular comprising a first processing device as device management master and at least one second processing device as device
  • the management client at least one field device, a wireless communication network and at least one mobile handheld device, providing a functionality to perform and execute the handling and managing of security credentials and other device specific and relevant parameters. Furthermore the invention related to a commissioning method for one or more field devices in a process automation system.
  • WirelessHART as a new communication standard in industrial automation introduces a number of new challenges compared to classical wired communication, which have to be addressed at an early stage in the respective Device Management System (DMS) during topology engineering and commissioning.
  • DMS Device Management System
  • the DMS requires instances for gateways and devices and must reflect the logical communication topology from the previous network layout.
  • security measures defined in the HART standard introduce additional complexity into the commissioning workflow.
  • Wired FSK communication is considered to fulfill this security requirement, are even fully autonomous wireless devices must provide a corresponding interface.
  • encryption keys may be pre-parameterized by the device manufacturer.
  • WirelessHART uses symmetric encryption, namely usage of the same key for encryption and decryption, for the authentication and communication between field devices and wireless access points. Corresponding keys must be available within both the gateway and the field device that wish to communicate.
  • a gateway receives an individual join key per device. To validate a join request, it requires a list of join keys and corresponding device IDs (hardware addresses). There is no way to disable encryption and authentication, but for ease of use the security level can be lowered. A common join key may then be shared between the devices in a network, and any device with a valid key is allowed to join.
  • the WirelessHART - devices must be connected to a "join key source", for example a commissioning station/engineering/handheld, via a secure connection or communication line.
  • Said connection typically is realized via a wired FSK Modem connection or a short-range IR connection, which all devices must support, even fully autonomous ones.
  • a HMI (human machine interface) port is also technically possible, but not standardized among manufacturers. Any wired port must be exposed during commissioning, whereby only the non-standard HMI port allows the device to remain closed.
  • the devices are co-located to a stand-alone or DCS (Distributed Control System)-integ rated DMS.
  • DCS Distributed Control System
  • the communication gap between the gateway and DMS has to be bridged somehow. Synchronizing information between these different locations would typically be done using a mobile device or a handheld respectively.
  • a bootstrapping method is required before wireless communication can take place (again).
  • At least two limiting factors for the speed of the network join process are the advertising frequency of the gateway and the available energy of the field device. The latter applies for or concerns both autonomous and line-powered devices; the energy from harvesters, batteries, and 4-20mA loops is typically scarce; a device must suspend some functions to keep operable for sensing, actuation, or communication.
  • the object of the invention is to provide an enhanced technical possibility for an efficient and easy to handle commissioning and maintenance of technical equipment and in particular an efficient and seamless handling of wireless field devices in a plant or technical installation, which allows to minimize or at least reduce join time.
  • the Process automation system comprises at least one field device, a device management system, a wireless communication network, and at least one data processing unit, wherein the device management system provides a functionality to perform and execute the handling and managing, in particular the synchronization, of security credentials and other device parameters for fieldbuses and/or field devices, wherein a mobile handheld device is provided to support a synchronization of said security credentials between the control system and the at least one field device, which in particular may be mounted and/or installed in the respective field prior to any synchronization and thus may not be reachable from the process automation system, i.

The user can compare them and interactively synchronize the data structures through bulk operations and drag and drop.
  • executable program code means are provided by the mobile handheld device and/or the DMS, which apply digital image processing routines and procedures to the two data structures to automatically compare them, discover differences, for example by use of pattern recognition, and synchronize both data structures automatically.
  • the handheld displays such mismatch to the user and prompts them for a decision how to resolve the situation.
