  • the present invention relates to providing protocol independent configuration of Intelligent Electronic Devices.
  • IEC 61131 is used to configure complex industrial controllers.
  • the IEC standard is an open international standard equipped with several programming languages, in particular two graphical and two textual PLC programming languages, in order to enable the PLC to control multiple devices (such as sensors, switches etc.) in a complex automation setup.
  • the primary function of these standard programming languages is to organize programs for a variety of devices and execute these programs for sequential and parallel control processing. The programs thus written and executed enable process control in automation systems.
  • OPC Ole for Process Control
  • FDT Field Device Tool
  • EDD Electronic Device Descriptor
  • FDT technology presently standardizes the communication interface between device configuration tools and engineering workstations. This technology is communication protocol independent and can work on any platform, irrespective of the software environment of both devices and host systems. FDT aims to allow access to any device, from any device through any protocol.
  • a device supplier typically develops a new Device Type Manager (DTM) for each of its devices or groups of devices.
  • the DTM captures all device-specific data, functions and rules such as device structure, communication capabilities, dependencies, HMI structure etc.
  • the DTMs are functional in providing access to device parameters, configuring and operating the devices and diagnosing problems.
  • the Electronic Device Description Language is a text-based language, which is used to describe the communication characteristics of IEDs and equipment parameters in Operating Systems (OS) and Human Machine Interface (HMT) neutral environments. Similar to FDT technology, EDD technology (by using the EDDL) also seeks to create a unified engineering environment that can support devices from any supplier, using any communications protocol, without the need of custom drivers for each device. FDT and EDD technology therefore lend themselves well to a holistic life-cycle management of devices, which are used with it. Independent of both these technologies is the concept of function blocks, which are traditionally used to model the process logic of a plant, rather than the business logic of an IED.
  • OS Operating Systems
  • HMT Human Machine Interface
  • EDD electronic device description
  • CFF capability files
  • An interpreter is commonly utilized to generate the device logic from the EDD or CFF representations, which are ultimately used for device configuration.
  • Siemens has a product SIMATIC PCS that does this.
  • HLL high level language
  • Devices are used for several purposes including monitoring and controlling a variety of physical parameters. These devices need to be configured in order to set the limits within which they are capable of operating. Configuring IEDs in large systems is typically done offline, owing to the multitude of IEDs present. At the commissioning stage, an engineer or an operator is often responsible for configuring the device.
  • a temperature transmitter or sensor which has an upper and lower limit which is linked to the sensor and therefore written to the IED during manufacturing, for example -30 deg to 100 deg Celsius.
  • One class of device (such as the temperature sensor) can be used to measure the temperature of several apparatus such as steam pipes or those responsible for cooling water.
  • a field engineer needs to configure a span according to the needs of the process in which he/she is utilizing the device. In the case of the device being used for several measurements, the engineer may accordingly configure the parameters of the device to 20-80 deg C for the cooling water and 90-130 deg C for a steam pipe.
  • US Patent 7,054,694 discloses a Process Control System wherein the engineering unit value scale data is managed centrally to ameliorate a lag (and consequent errors) between the operation values and the display values.
  • a soft PLC is proposed in which functions are written in software.
  • the soft PLC receives I/O data associated with devices (usually analog signals). The received data is then normalized and sent to the display unit, with the end goal of removing any transience in the data which is collected and that which is displayed.

  • Offline configuration is common practice because a plant might have thousands of EEDs and the configuration process begins much before the hardware is available. Further conventional configuration and control systems have to surmount the problems posed by the use of several programming languages for the devices themselves.
