HART technology has been shown to significantly reduce the time required to fully commission a network (loop). For example. devices can be more quickly verified because the device specific and application information are loaded into instruments which can quickly be verified by the host control system. Commissioning is further streamlined by connecting a PC configurator to each HART communication loop online either through the control system or a multiplexing I/O system. This eliminates the need to move the configuration device from one termination point to the next while commissioning devices on the network. Leading PC configurator applications also include a loop-test feature which ensures proper connections, and as-installed record-keeping features for long-term documentation and maintenance.
Highway Addressable Remote Transducer (HART) technology greatly improves the use in commissioning and configuration part in industrial automation system.
Here’s how HART assists in these areas:
Streamlined Commissioning Process
Reduced Time for Device Verification
It also presents the benefit of enabling fast verification of devices because it is possible to upload particular device and application details into the instrument.
This data can be quickly verified by the host control system, thus incurring limited time on commissioning every hub.
Centralized Configuration
To improve configuration, there is always a PC based configuration application that is linked to each HART communication loop.
It also reduces the inconvenience of actually having to carry the configuration device from one termination point to another; the tools can be used in configuring several devices at a time in the network.
Loop-Test Features
Most of the HART-enabled devices have features that can be used for looping testing these features make it possible for the user to test the credibility of the given analog signal. This applied feature also assists in ensuring right connectivity and could validate if the analog signal is as per the value that the device communicates, which would be useful while commissioning.
Enhanced Configuration Capabilities
Device Identification and Configuration Verification
During the commissioning phase of a control system, configuration data with identification data and tags of a field device can be checked with a device configurator with the help of a hand-held communicator or PC link with the device. This help to make certain that all configurations are correct and meet safety and the regulation requirements.
Record Keeping
HART configurators support detailed records as can be evidenced by the above components. It can hold configuration data – something extremely important for compliance and that is also archived for future use or in the case of device replacement.
Calibration Support
HART technology comprises of command that makes it easy to calibrate the field devices and be assured of reading of process variables. This is important in order to maintain the confidentiality of the control system and to put the devices into right parameters.
In conclusion, it can be stated that the application of HART technology contributes to the increase of commissioning and configuration effectiveness and reliability within industrial environments by cutting down on the time needed for the verification efforts, enhancing the centralization of configuration activities, and offering the set of powerful tools for the purpose of device integrity examination and documentation.
