How do you go from serial comms to serious SCADA without downtime or compromise?

Based in Cincinnati, Ohio, Varland Plating has provided high quality, precision barrel-plated finishes to their customers since 1946. Varland manually performed plating operations until the early 1990s. Then automated systems improved turnaround times and product quality. More recently, the company saw the advanced capabilities of Opto 22's groov products—smaller equipment footprint, Ethernet, data visibility, and more—and entered a new era of industrial automation.

In this case study, find out how Varland Plating was able to bring a 30-year-old automation system into the future without downtime or compromising their SCADA goals.

This technical tip post covers the history and challenges of connecting RS-232 serial devices together.

The nice thing about standards is that there are so many to choose from. Like every profession, industrial automation has a veritable cornucopia of standards we need to be aware of. RS-232 is no different or special in that regard.

Let's take a look at the history of this hardware communication standard and use that as a springboard. We'll take a look at how modern microprocessor technology can be adapted to this very commonly used data communication standard in the industrial automation world.

Firmware update 1.4.0 is now available for the groov EPIC processor, GRV-EPIC-PR1.

Our engineering team released an exciting new update for groov EPIC this week. Here are some of the highlights.

Learn how to set up, install, and communicate using a groov EPIC serial I/O module.

Many industrial automation applications require communication between the controller and multiple serial devices. The GRV-CSERI-4 module provides four independent and isolated serial ports for this purpose. Each port is software configurable to communicate with RS-232 or RS-485 (half duplex or full duplex) serial devices.
