Combustion control systems go modular with Honeywell Slate

A typical combustion system is complex to say the least.  It is usually made up of various devices from multiple vendors that have to be combined and connected in order for the system to work.  These systems are not typically flexible and are hard to change once the system has been set up.

Honeywell has come up with a completely new system that provides limitless flexibility with fewer components.  This product has been designed as a fresh start for the combustion industry or in Honeywell’s words, “It’s time to wipe the SLATE clean.”

Air Bubbler Systems: Old Faithful Liquid Level Measurement

In an ideal world there would be a perfect liquid level measurement system that would work for every liquid and every application.  Unfortunately, that product does not yet exist, leaving operators and technicians to go through the trial and error process of finding the level instrumentation that will work for them.

So in this high-tech world, is there still a need for the old faithful pneumatic systems like air bubblers?  The answer is YES!  Why? Because air bubbler systems work when other systems fail.

Air bubbler systems will work with the more difficult of liquids such as…

Using a Honeywell Paperless Recorder as an Alarm Annunciation Panel

Written by: Dan Weise

It’s surprising to me how many Honeywell Trendview recorders are used primarily for alarming. People tell us that they like the alarm screens on the old-style annunciation panels. On a digital recorder, they look like this:

Users say “It’s easy to tell at a glance, which points are in alarm because the red really stands out. And the process values show up right there under the tag. Everything we need is in one place”

Changing the COM port for a USB HART modem in Pactware

Written by: Dan Weise

I couldn’t communicate with a HART device. The configuration software I was using, Pactware, thought the USB HART modem was on COM 3, while Windows’ Device Manager showed it was actually on COM 6.

To change the COM port in Pactware to COM 6, I right clicked COM 3 and selected Parameter:

Five Key Features Required for a Perfect Fit Distributed Control System

If you work in the industrial sector, you understand the never-ending push to increase uptime and improve reliability at your plant. Today’s processes require faster and more accurate engineering. Because of this, most companies are looking for ways to boost operational effectiveness and increase maintenance efficiency at their plants.

A distributed control system (DCS) is a control system where control elements are distributed throughout the system, as opposed to using a single controller at a central location. But how do you choose the right DCS? And how do you decide what functions are critical to your process?Functional_levels_of_a_Distributed_Control_System.svg

Honeywell recently released a white paper that discusses five key features for a perfect fit DCS if you’re thinking about implementing one at your plant.

Why won’t Pactware work with the Siemens LUT 400?

Written by: Dan Weise

I’ve used Pactware for a couple years now, so I was surprised when I couldn’t get the Siemens LUT400 to work with the software. The LUT400 ultrasonic level and flow controller comes with a DTM file that I installed before opening the Pactware software.

The DTM file can be downloaded from this link:

Once it had been installed, I opened Pactware and updated the device catalog, as seen in the picture below:


But when I attempted to establish a HART connection to the LUT400, I got an error message:

How to Measure Thermal Energy

As energy costs and environmental concerns continue to rise, we count on our facility managers to take control of building/factory energy consumption. To reduce their companies’ carbon footprints, facility managers have begun implementing energy management programs to control their systems, optimize efficiency, and manage expenses.

But how are they doing it?

Let’s say you are trying to cool your facility. There are two steps to determining how much energy is consumed in the process. Read the rest of this entry »
