Node-RED y PLCs

Node Red se puede comunicar con PLCs usando Modbus o con los Scadas usando OPC u OPC-UA.

Pero existen nodos específicos:

• PLCs Siemens S7: https://flows.nodered.org/node/node-red-contrib-s7

PLCs con Node-RED integrado:

• Simatic 2040: https://www.infoplc.net/descargas/109-siemens/comunicaciones/2847-manual-simatic-iot2040-node-red
• sysWORXX CTR-700: https://www.systec-electronic.com/en/products-technologies/internet-of-things/sysworxx-ctr-700/ y https://www.systec-electronic.com/en/node-red-nodes-for-the-sysworxx-ctr-700/

Node-RED y Fiware

Existen varios nodos de Fiware para Node-RED:

• Node Oficial: https://flows.nodered.org/node/node-red-contrib-fiware_official
  • NGSI(v2,LD) Entity
  • NGSI(v2,LD) Dataset
  • NGSI(v2,LD) Update
  • NGSI(v2,LD) Subscription
  • NGSI(v2) v2ToLD
• node-red-contrib-fiware-orion: https://flows.nodered.org/node/node-red-contrib-fiware-orion
• node-red-contrib-nec-fiware: https://flows.nodered.org/node/node-red-contrib-nec-fiware

El nodo principal es https://flows.nodered.org/node/node-red-contrib-fiware_official y el repositorio es: https://github.com/FIWARE/node-red-contrib-FIWARE_official. Lo que hace es trabajar con el Orion context broker, realizando varias operaciones.
