PLC Learning Series – HMI – Interfacing

PLC Learning Series – HMI

A human-machine interface (HMI) is present in some form for every PLC. The HMI connects a user to a machine system to exchange information or control data. This interaction with the system can be through hardware or software. HMIs offer different people information and control in many ways for the automated system. Operators, supervisors, mechanics, … Read more

Omron PLC Node-RED Serial Communication

PLC manufactures have their own proprietary protocols. These methods of communication will allow you to program the controller. Other protocols will allow you to collect and log information from the programmable logic controller. Node-RED has the ability to read and write to the Omron controller using special protocol commands. We will connect Node-RED to the … Read more

Simple Click Data Logging – Node-RED

Simple Click Data Logging

We will now be looking at simple data logging using a Click PLC with an Ethernet port. Node-RED will be used to communicate to the controller via Modbus TCP protocol. Information collected will be then stored in an SQLite SQL database. A Raspberry Pi 4 single-board computer will be used for the Node-RED collecting and … Read more
