- How do you get machine data without interfering with the process?
- What's an easy way to monitor temperature in a server room?
- How can you control the flow of heating and cooling water in your HVAC system?
These are the kinds of fundamental questions that come up over and over in automation applications, and our new Automation 101 video series aims to answer them.
Does it comply?
For some time now we've been working to make sure our products comply with the latest requirements for RoHS (Restriction of Hazardous Substances) and CE marking (a mark indicating that the product meets all legal requirements to be sold in the European Economic Area, or EEA).
As an applications engineer, sometimes known as OptoMary on our OptoForums, perhaps I shouldn’t have favorite customers. They’re all my favorites!
Sure, our products and people have helped build flashy Vegas shows, huge amusement parks, and various NASA endeavors that we may or may not be allowed to discuss in detail. We also have the less flashy water/wastewater installations and beloved "dam customers" that can be pretty Coulee, too.
In these Adventures of an Applications Engineer posts I'll share some of my favorite favorites.
Maybe you're monitoring temperature, or controlling a production line, or getting data from a load cell. Whatever your goal, you want to get the I/O that works best for your application.
Or maybe you happen to notice we have more than one SNAP-AIV voltage input module and wonder how they're different.
Here are a couple of ways to find a SNAP module with the features you need and compare similar modules.
It's easy to get confused between Opto 22 SNAP PAC controllers and SNAP PAC brains.
They're both intelligent processors for automation, some of them look alike, and there's even overlap in what some of them do.
Let's take a look at how SNAP PAC controllers and brains are similar and how they're different.
There’s a lot of talk these days about artificial intelligence, the cloud, and cognitive computing.
But what the heck do those things have to do with industrial automation, and why should automation professionals be getting up to speed on these technologies?
Are you using G4 or SNAP digital I/O with your Raspberry Pi®?
A lot of engineers are finding a Pi surprisingly useful in real industrial applications, as well as for prototyping and experimenting. Used with Opto 22's reliable industrial I/O, your Pi can safely switch 5-60 VDC, 120 VAC, and 240 VAC loads.
Two of our software development kits (SDKs) have just been updated to provide support for Microsoft® Windows® 10 Professional, 8.1 Professional, and 7 Professional, both 32-bit and 64-bit.
The PC-Based Direct I/O SDK for PCI Adapter Cards is for direct, high-speed control of digital I/O points.
Ethernet networks have taken over as the prominent bus architecture for industrial automation networks. And for good reason.
Ethernet simplifies and homogenizes connectivity between industrial devices. We don’t have to worry about male or female DB9 and DB25 serial connectors, no concern for DTE or DCE devices, and forget about straight-through vs. null-modem cables. In general, the world is a much happier place.
However, even with the added simplicity Ethernet offers, troubleshooting Ethernet networks can be a bit more involved than serial networks.
Let’s assume you’re trying to establish communication with an industrial Ethernet device that for whatever reason has dropped off the network. Here are a few tips I always use when starting to troubleshoot an industrial Ethernet network.
