Request-response vs. publish-subscribe, part 2: Which to use?

Posted by Jean Femia on Feb 27, 2018 10:00:00 AM

In part 1 we met two communication models for computers on a network: request-response and publish-subscribe. Now let's take a look at when you might want to use each, and why.

Request-response: proven and reliable

In a request-response architecture, each client opens a direct connection to each server, because the client requests data directly from the server.

In automation, typically clients are PCs and servers are PLCs or PACs. So each PC opens a direct connection to each PLC or PAC from which it needs data.

New IoT Webinar: Live technologies demo

Posted by Jean Femia on Dec 7, 2017 11:18:56 AM

Is the Internet of Things (IoT) just a lot of hype, or can the IoT technologies we keep hearing about provide real value?

RESTful APIs, Node-RED, and MQTT are just some of the new technical terms we're all starting to learn.

If you'd like to see these technologies in action to understand how they might be useful for your applications, then join us for a new webinar on December 12.  

Opto 22's Senior Applications Engineer Kyle Orman will demo these technologies and more. He'll show you how to exchange live data between real-world I/O and IoT platforms. 

You'll see: 

- IoT hardware that's proven in industrial locations
- RESTful APIs to get data from PAC controllers
- Examples of simple logic flows created with Node-RED 
- Ignition Edge® OPC-UA drivers built into the  groov Box
