The PowerFlex 525 series of Variable Frequency Drives from Allen Bradley is highly utilized and respected within the automation field. The drives are compact, versatile and easy to use. We’ve written an extensive tutorial on how to get started with these drives in a previous tutorial; it covers how to initialize the drive, connect it to an EtherNet/IP based PLC and how to set the right parameters. In this tutorial, we’re looking to expand on the concepts and demonstrate a way to access and utilize the multiple Input and Output options available on the drive. The reason you may want to utilize the IO is to save money on purchasing external components, integrate instrumentation into your drive and save floor space, wiring and cost. We’ve seen the need to integrate closely related sensors into a PowerFlex 525 application; this would be the right way to do it.
MQTT is a communication protocol that has taken off in the IIoT community. It’s a light-weight, efficient protocol that works through a publisher / broker / subscriber model. It creates an easy way for field devices to communicate and retrieve data from a single location. In this article, we’ll go over MQTT and dive into an example of how you can publish data using a groov EPIC PAC and retrieve the data using a MQTT client.
