Setup/Configuration 

 

Configuration/Setup

You may have been wondering if all devices around the plant can be configured using the same single software. With a system based on EDDL it is easy. The information provided here includes many examples of setup of simple and sophisticated (complex) devices and serves to explain how the device manufacturers make it easy to configure their device from any system.

Plants have hundreds or thousands of devices of different types from different manufacturers which they must be able to configure.

Configuration of field devices is can be done using handheld field communicator or intelligent device management software based on EDDL, whichever suits the task at hand best.

EDDL technology makes device setup easier thanks to user guidance such as wizards as well as know-how made available from the device manufacturer's experts. The result is faster startup.

What setup is possible for intelligent devices is not well understood and will therefore be explained in technical white papers and videos below. The importance of EDDL for configuration is also explained.

EDDL technology supports small portable field communicators for easy configuration in the field, there is no other way to achieve a comparable result.

What is parameterization?

The word parameterization is derived from the German word “parametrisierung” and refers to configuration/setting of parameters in a device to change the way the device operates. It is used to distinguish from “configuration” which might also include selection, linking, and scheduling of function blocks. For instance, portable tools like a handheld field communicator or laptop with interface and software are typically capable of parameterization; changing the values of parameters, but not able to add, delete, or link function blocks.

What is device commissioning?

Device commissioning are the steps required for putting the device into service. This may include things like communication settings, configuration, and connecting the device, as well as calibration and other tuning required for the device to operate. These aspects are explained in detail in the configuration tutorial and calibration tutorial respectively.

How do I commission a smart device?

A smart device is configured and calibrated before it is put into service. This is usually done using a portable tool such as a handheld field communicator or laptop with interface and software. These aspects are explained in detail in the configuration tutorial and calibration tutorial respectively.

How do I commission a Fieldbus device?

A Fieldbus device is recognized by its tag. The tag is usually assigned before the device is connected to the bus such that the system can automatically assign and address and download the configuration to the device without any person having to touch the system software – the person uses only a screwdriver. Assigning a tag prior to connecting the device to the bus is not required, but then a person must instead manually make the system accept the device. Some systems require the address to be assigned before connecting it to the bus. The device configuration is usually downloaded from the system as part of the commissioning process. These aspects are explained in detail in the configuration tutorial and calibration tutorial respectively.

How do I provision a wireless device?

A wireless device is recognized by its tag. A network ID is required for the device to know which of many networks to join. A join key is required for security. The tag, network ID, and join key are assigned using a portable tool such as a handheld field communicator or laptop with interface and software. A wireless device is configured and calibrated before it is put into service. This is usually done using a portable tool such as a handheld field communicator or laptop with interface and software. These aspects are explained in detail in the configuration tutorial and calibration tutorial respectively.

How do I document device configuration changes?

Intelligent Device Management (IDM) software part of an Asset Management System (AMS) can automatically document configuration changes by logging it as an event in an audit trail. A unique characteristic of EDDL technology is that enables audit trail for all devices, not just some. Changes not made from the IDM software, for instance from a portable tool such as a handheld field communicator or laptop with interface and software cannot be logged with as much detail. Audit trail is explained in detail in the configuration tutorial.

What is a configuration audit trail?

An audit trail is an event log. Configuration changes made from the IDM software are logged time stamped and include information such as who made the change and annotations explaining why the change was made. A unique characteristic of EDDL technology is that enables audit trail for all devices, not just some. Audit trail is explained in detail in the configuration tutorial.

What is a device template?

A device configuration template is a file that contains the standard configuration to be used for a particular device. The device manufacturer may provide a recommended device configuration template, but plants may also develop their own enterprise- or site- specific device configuration templates with corporate preferences. Device templates are explained in detail in the configuration tutorial.

Can changes be made to safety-related devices?

4-20 mA/HART devices used as part of a Safety Instrumented Function (SIF) must be write protected by a hardware switch or jumper because HART is not a safety protocol.
