Learn how PLC+HMIs outperform microcontrollers without breaking the bank

ErreDue manufactures gas production and purification equipment with a focus on accessibility and ease of use.

ErreDue developed a new line of micro-generators for Hydrogen, Oxygen, and Nitrogen generation. Although most of their competitors use microcontrollers on similar product lines, ErreDue wanted to use PLC control; their engineers liked the reliability and flexibility offered by PLCs. They selected the Vision350 PLC+HMI, because they wanted a control option that was compact without compromising usability and functionality.

In Their Own Words:

“This device [Vision350], with an Ethernet port onboard, makes our generators better performing, more versatile and more innovative than our competitors.” – Claudio D’Angelo, ErreDue

italy-Erredue2-1024x768They selected a Unitronics Vision350; this all-in-one controller offers a full-function PLC integrated with a touchscreen HMI and onboard I/O.  The all-in-one approach added a lot italy-Erredue1-1-1024x665of value for ErreDue.  They were able to integrate an easy-to-use HMI panel, a powerful CPU, I/O and Ethernet and serial communications without adding a lot of bulk to their system. In addition to matc
hing ErreDue’s physical requirements, the Vision350 also offered impeccable performance.  Engineer Claudio D’Angelo raves that “this device, with an Ethernet port onboard, makes our generators better performing, more versatile and more innovative than our competitors.” Most of ErreDue’s competitors use microcontrollers with monochrome LCD displays and membrane function keys, so the color touchscreen and function keys of the Vision350 were a major step up for the user interface and experience.  Additionally, the Vision350’s robust Ethernet and RS485 communications enabled the generator to be monitored and controlled remotely, with fast and reliable data exchange.The Unitronics Vision350 added a lot of value for ErreDue, without a lot of extra costs.  D’Angelo adds “the software programming is easy and intuitive. Technical support is fast, punctual, and reliable.”
