Powerful new HART communicator

HART is the standard for process instruments, with more than twice as many installed devices as its main alternative. Well over 35 million HART devices have been installed since the protocol was developed, which means every instrument engineer and technician must have HART knowledge as part of their core skill set. Meriam has just released a new HART communicator, the MFC5150x.
“We developed the 5150 to make the customer’s job easier,” says John Balogh, Meriam’s engineering manager. “This will be the first Class 1, Division 1, intrinsically safe device able to read the complete library of HART device descriptions (DD) directly, with no translation. That’s over 1200 devices, and more than 2,4 Gb of data contained directly in the communicator.”
The device is supplied with a fast 1 GHz processor, 256 MB of RAM and 512 MB of flash memory. It is capable of supporting up to an 8 GB SD card, which gives it the ability to store every existing DD file and then some. “There is now no need to manage which DDs are stored on your device, or to suddenly have to go back to the shop because the one DD you need isn’t on the communicator you have,” explains Balogh.
“We built the 5150 on HART Communication Foundation’s SDC-625 infrastructure for reading DDs directly,” he adds. “This enables communication to take place with any registered or unregistered HART device, ensuring that the HART transmitter will connect to the 5150 regardless of brand or model.
“And because the 5150 reads DD files directly, customers don’t have to wait for files to be translated into data a communicator can read. Typically, a translation can take anywhere from three months to three years, if ever. Reading a DD directly really helps the customer have confidence that the communicator will work right out of the box and for years to come with no problems.”
The unit has a wide-angle touchscreen for what Balogh describes as excellent anti-glare viewing, which can be used in darkness or in bright sunlight. The full keyboard and intuitive international icons similar to those of a smartphone, make all the functions easily navigated. No stylus is required for the touchscreen.
The 5150 has contextual help and can play video, so that instructional videos can be loaded onto the device for use in the field. There are hyperlinked menu paths for fast navigation via a single touch, and there are teachable, device-specific shortcuts.
The communicator is supplied with a 9 400 mAh rechargeable battery, which provides for more than 10 hours of continuous use and over 200 hours in standby mode.
The device has an ‘instant-on’ feature. The extended battery life and instant-on means that the 5150 is capable of getting through an entire shift without having to be recharged. When it does, it sits on the supplied cradle, which has an integral USB connection to the user’s PC.
The 5150 is rated IP54 for ingress protection and has overmoulded bumpers for impact protection. It is not necessary to purchase an aftermarket protective boot for the 5150. The handle is only eight inches in circumference with the smallest point where the operator’s hand will rest the most. It is designed to be ergonomically easy to hold and use.
Through the supplied charging cradle, the 5150 has USB connectivity, so it can be updated over the Internet without a subscription fee. Multiple languages and TAB access to multiple panes are supported.
“The MFC5150x HART Communicator is the latest addition to our line of intrinsically safe communicators and calibrators,” concludes Balogh.

Editor's Choice Fieldbus & Industrial Networking
The widely held belief in many plants that tuning will solve all base layer control problems is completely fallacious. Bad tuning is generally not the main reason for loops to perform badly. It is important when performing optimisation that all elements in a loop are considered, in addition to the control strategy, before even thinking of tuning.
