17 Jun 2021

 

Industrial monitoring and control world has always been associated with PLC concept. Until recently, programmable logic controllers were always the first option to digitalize a factory, but this paradigm has just changed. Devices like eManager or Raspberry Pi provide a solid alternative, or even a complement, to make the leap into Industry 4.0.

 

What is a PLC?

A PLC (Programmable Logic Controller), or industrial controller, is an industrial computer with capacity to collect and process data from sensors, meters, devices, machines, buttons, and other type of digital and analog inputs. This data is processed and used to manage outputs, including valves, relays, engines, ….

A PLC is an element designed to automate industrial processes using ladder or block diagrams.

 

What is a Raspberry Pi?

Raspberry Pi is a single-board low-cost computers range initially designed to promote computer science learning on school, but nowadays is widely used on IT prototypes, robotics and other applications related with multimedia.

Nowadays we can find industrial versions of Raspberry Pi which include though enclosure, extended temperature and humidity range, and conformity with the main standards CE, UL and RoHs.

 

What is an eManager?

eManager is and industrial IoT-ready controller ideal to easily developing industrial and edge computing applications. It is equipped with a Multilanguage API which include the most popular programming language for IoT applications (C, C++, Python, Go, Java...) and Node-RED software fully integrated.

Node-RED includes protocols such as Modbus, BACNET, MQTT, OPC-UA, together with easy communication with platforms like Amazon WBS, Microsoft Azure, Google Cloud and more.
