Now and then, I get signed up to do something different. Most of us have that clause in our job descriptions: "or any other duties as directed." 😁 In this case, I assembled a cabinet with a [*groov* EPIC](https://www.opto22.com/products/groov-epic-system) on a chassis four rack. The four I/O modules were a mix with a total of 30 channels. Of course, after the wiring was done, a sanity check was in order—or, said another way, a point-by-point check that everything was working as it should have been. Sounds tedious, right?

Here are some insights on designing a cybersecure controls system that an IT department will know and trust. The simple action of picking up your cell (mobile) phone and making a call belies the enormous amount of work that goes on behind the scenes to get the protocols and encryption standards approved—so that each phone can connect to the cellular network securely. If we homemade our own cell phones, it's understandable that the network provider would (and should) quickly become “the department of no,” not allowing us to connect to their network. Many things could go wrong, and they would soon be on the hook for any issues our device might cause. It really is no different from when we show up at the factory with an Ethernet-enabled PLC and ask our IT department to connect it to the factory network. They don’t know anything about the PLC! And they have lots of questions...

Is it just me, or are the years flying by faster than ever? And as if time is not going by fast enough, I’d like to say how much I'm looking forward to writing this blog at this time next year. Why?

Just like the [*groov* EPIC firmware update](https://blog.opto22.com/optoblog/update-to-groov-epic-3.6) 3 weeks ago, we have added WPA-2 Enterprise WiFi connectivity to the *groov* RIO [MM1](https://www.opto22.com/products/product-container/grv-r7-mm1001-10), [MM2](https://www.opto22.com/products/product-container/grv-r7-mm2001-10) and [EMU](https://www.opto22.com/products/product-container/grv-r7-i1vapm-3) (Energy Monitoring Unit).

I’ve had the line “Don’t it always seem to go, you don’t know what you’ve got till it's gone” from Joni Mitchell’s 1970 hit *Big Yellow Taxi* rolling around in my head the past few weeks. I've been working on building web pages for a personal project I will use on my PC and my smartphone, so they must be responsive. Because I’ve been working with *groov* View for so long, I’d forgotten just how really, really hard it is to use standard web design tools to build responsive web pages with graphical elements. There is so much HTML and CSS development required to get a single webpage to display nicely on both a PC-sized screen and a smartphone-sized screen (and everything in between). With *groov* View, you don’t have to write a single line of code—it's all just drag and drop!

Opto 22 customers have it. With all the buzz of Opto 22's 50-year anniversary in the air, many of us here at Opto 22 headquarters in Temecula, California, are sharing our Opto stories—mostly centered around memories of people and events. It wasn't until a live-chat message came in from a customer asking about migrating PID loops from a legacy Factory Floor application to PAC Control running on a *groov* EPIC that this blog post crystallized in my mind's eye. What struck me even more than the question about migrating those mid-1990s PID loops is just how profound it is that the question actually does have an answer! (Stay tuned until the end.)

Whenever I say this blog title out loud to the Premium Factory Training class attendees, I get some funny looks. I'm not sure if it's the Aussie accent, or the idea of adding delays to speed up that causes the double-take chuckles. Compute power has come a long way in the last 10 years or so, but regardless, we programmers of all things industrial still need to be mindful of optimizing our code and systems to run as smoothly as they possibly can. Arguably, one of the biggest tips for programming in PAC Control I can share with you all is to add delays through your flow charts and OptoScript blocks.

A well-known electric car company is somewhat famous for its ability to add features and fix bugs with over-the-air updates to millions of cars. Of course, they are not the only ones with this feature. Many companies have been updating their hardware with firmware updates for decades, but it really captures the imagination when the hardware is something you drive. Closer to our hearts and minds, Opto 22 has been adding features and squishing bugs on our controllers for more years than most of us can recall (it's our 50th year in 2024!). There are a few SNAP I/O modules that can have their firmware updated via our PAC Manager program—the serial data ones for example—but now with *groov* EPIC and RIO, ALL our modules can have new features and refined performance added at the click of a button.
