Features: HIMs offers the following features.

HIM Initial Operation on New Drive Powerup: When you first power on a new drive, the HIM goes through an initial operating sequence that accomplishes the following: invites you to choose a language, begins a drive start-up procedure, and may initiate a port verification check.

Display Contrast Adjustment: For better viewing and text readability, the HIM display’s brightness can be adjusted.

Setting the Date and Time of Host Drives: PowerFlex drives contain a real-time clock that gives the ability to timestamp faults and alarms. They are used for real-time application realization. This clock has to be set up exactly to give relevant time stamp data. The time of the real-time clock may be modified using HIMs.

Customizing the Name of a Drive or Peripheral: The host drive and each of the host drive’s connected peripherals have a default name. To enhance user experience and comprehension, HIMs can edit any of these default names.

Making the Process Screen Your Own: Different drive monitoring items, a scale factor, or different drive parameter wording may all be adjusted on HIM’s Process screen. HIM’s process screen can be shown as a single-line view screen or a multi-line view screen to adjust one parameter while observing the other.

Resetting the Host Drive or it’s Peripherals: The drive and its peripherals can be reset by disconnecting and replugging any connected peripherals (power cycling). The drive and peripherals can be reset using the HIM if doing so is cumbersome or impossible because of application limitations.

Restoring the Factory Defaults: HIMs may be used to restore the factory settings of the PowerFlex drive and its attached peripherals.

Changing the displays’ flashing to indicate a fault: You may configure HIMs to flash a display when a fault is identified. If a problem with the host drive or any of its connected peripherals is found, a popup Problem Display screen appears. By default, just the Status Bar flashes to notify the operator.

Viewing/Editing Peripheral or Drive Parameters: You can view or access the parameters of the host drive as well as the parameters of external devices connected to the host drive through HIMs.

CopyCat Function: The PowerFlex drives’ CopyCat feature allows you to upload specific parameter settings for the host drive or any of the attached peripherals into the HIM. This data may be utilized as a backup or moved to some other PowerFlex drive or external device by downloading the data from the HIM’s memory.

Making Use of an Access Code: All parameter configuration settings for the drive and its connected peripherals can be protected against unauthorized access using an access code. You may configure the access codes using HIMs.

Updating the HIM Display’s Text Language:The display text for all HIM screens can be translated into any of the languages recognized by that HIM. That allows field operators to choose the language of their choice. English is the default language.

PanelView Plus 6 vs Plus 7: Is It Worth Upgrading?

Upgrading your hardware always feels like a special occasion, especially if it’s for something you handle every day. After all, who doesn’t like faster hardware, more refined software, and a more responsive user interface? The reality becomes a little more complicated when the equipment in question is tied directly to production. In industrial automation, replacing hardware is rarely as simple as unplugging one terminal and mounting another in its place. This hesitation is part of the reason you will still see the PanelView Plus 6 in so many facilities, even with the newer PanelView Plus 7 series on the market. This boils down to compatibility concerns, retrofit cost, downtime windows, network architecture, and operator familiarity. In some situations, moving to a Plus 7 terminal can modernize an entire machine interface. In others, it can create more work than value. Before we get into comparing specifications and features, it helps to understand where these terminals are typically...

PanelView Performance in Harsh Environments

For industrial automation engineers, the HMI isn’t just a screen—it’s the nerve center of the entire operation. And when you put that center somewhere tough, like a food processing plant, offshore rig, or chemical facility, ordinary commercial displays just don’t cut it. This is where Rockwell Automation’s PanelView family really stands out, specifically the PanelView Plus 7 Performance and ArmorView Plus 7 terminals. You can read spec sheets all day, but it’s more important to know how PanelView terminals survive wild temperature swings, corrosive gases, and brutal washdowns. dLet’s dig into what makes the PanelView excel in harsh, demanding environments, so you know your HMI investment won’t let you down. First off: temperature. Electronics hate extreme heat and cold, and PanelView terminals have to stay stable, even when sealed up tight inside enclosures with bad ventilation. Rockwell spells out exactly what these displays can handle. Most PanelView models—the 6.5-inch, 9-inch...

What ‘Real-Time’ Actually Means in Industrial Control

If you have spent any time reading about automation equipment and how they work, you would come across phrases such as: “Real-time control”, “real-time monitoring”, “operates in real-time”, or “real-time deterministic behavior”. It becomes one of those things that you might be afraid to ask about because it’s thrown around so much that it seems like it’s common knowledge. Alas, we at DO Supply don’t judge and encourage learning opportunities, so let’s get you up to speed on what ‘real-time’ actually means. In the world of industrial control, “real-time” is a more precise engineering term. It means predictable, rather than “fast”. A real-time system isn’t defined by how quickly it responds, but by whether it responds within a guaranteed, bounded window of time, every single time. That guarantee is what engineers call determinism, and it’s the whole reason the phrase gets used so often around PLCs, drives, and industrial networks. To put it in perspective, say a video game you’re...

MicroLogix 1200 Selection Guide

In industrial automation, there are three types of controllers: Those that are replaced because something better came along, those that are swapped out because they finally gave out after years of service, and those that never get replaced at all because nobody could find a good enough reason to mess with what’s working. The MicroLogix 1200 fits right in that last category. These middle-child controllers in the MicroLogix family have been holding down applications for over two decades now, quietly doing their jobs in packaging lines, water treatment plants, material handling systems, and thousands of other installations. These controllers are wired in, commissioned, and essentially forgotten in the best possible way. Rockwell Automation has long since moved on to newer platforms, but in the automation world, “discontinued” and “gone” are two very different things. What made the MicroLogix 1200 popular in the first place is still what keeps it relevant: expandable I/O, a...

MicroLogix 1100 Selection Guide

If you’re considering a compact controller for a small to mid-scale automation project, the Allen-Bradley MicroLogix 1100 deserves a close look. While it may be a legacy system, the MicroLogix 1100 still strikes a balance between capability and footprint, giving engineers a robust feature set without the overhead of a larger platform. The Micrologix 1100, at its core, is a fixed I/O programmable controller built around 18 onboard I/O points: 10 digital inputs, 2 analog voltage inputs (0-10V DC), and 6 discrete outputs. What sets it apart from this class of controller is the inclusion of a built-in Ethernet/IP port alongside an isolated RS-232/RS-485 combination port, an onboard LCD display with keypad, a real-time clock, and support for up to four 1762 expansion I/O modules. While the MicroLogix 1100 series has only four controllers, we will go over each one, the expansion I/O lineup, and common applications to help you select the right configuration for your project. As we mentioned...

MicroLogix 1000 Selection Guide: How to Choose the Right Allen-Bradley PLC

The Allen-Bradley MicroLogix 1000 has been around the block for a while, long enough to be a seasoned veteran before some of today’s engineers even start their first internship. Rockwell Automation has since discontinued the line, but if you’ve spent any time in the field, then you know that “discontinued” doesn’t mean gone. In fact, these little fixed I/O controllers are still working in packaging lines, HVAC systems, conveyor controls, and countless other applications where they were originally installed and never gave anyone a reason to rip them out. That being said, there are still several reasons to pick these controllers for your project. Whether you’re sourcing a drop-in replacement for an existing system or maintaining a fleet of legacy machines, this guide is for you. We’ll walk through the part number system, the different I/O configurations, power supply options, and output types so you can confidently select the right MicroLogix 1000 for your application.
