Click Plus Data Logging

We will now look at the data logging capability using our Click plus PLC. Data logging is the collection of data over time. This is usually used for data analysis at a later time. The amount of data (System Information) stored and the frequency of the storage will depend on your specific application. The hardware used to store the data is usually called a data logger. Using the information from our last post, the MQTT information collected (Temperature in Atlanta and Click Analog) will now be logged in two different ways. A micro SD card on the Click Plus will be used to store the data every minute in a CSV (Comma Separated Value) file. Node-RED will also be used to store the same data in a SQL database. Let’s get started on how to use these data loggers. Features of the new Click PLUS PLC (C2-0xCPU) includes the following: • Micro USB • DHCP support • DNS support • Wi-Fi (programming and Modbus TCP) • Bluetooth (Wi-Fi) provisioning • SD Card (Data Logging) • Data Logger • Network Time Service • MQTT (Publish/Subscribe) • Required PLC Password • Disable Ports • Strong Password Support • Disable Ping Response • Encrypted Password Transfer More information can be obtained at our website. This includes all of the links mentioned in this video. https://accautomation.ca/click-plus-data-logging-csv-file-sql-database/ 00:00 Click Plus Data Logging 01:20 Click Plus Hardware 02:37 Click Plus Data Logging Setup 05:14 Click Plus Data View / PLC | SD Control Center 06:15 Click Plus Data Logging Log 08:49 SQLite Database Setup 09:40 Node-RED SQLite Previously we looked at the following: Click Plus Software Installation https://accautomation.ca/click-plus-software-installation-version-3-00/ https://youtu.be/6uQQzyZ-O3s Establish Communication https://accautomation.ca/click-plus-establish-communication/ https://youtu.be/1Bnx3IROCqk MQTT Communication https://accautomation.ca/click-plus-plc-mqtt-communication/ https://youtu.be/wzUBolN9KjQ CLICK PLCs were designed with simplicity in mind, providing reliable control at a low, low cost and with little to no learning curve. This simplicity makes CLICK a perfect solution for small machines, home automation projects, pneumatic applications, or anywhere a simple system needs a budget-saving control solution. Building on the original CLICK’s simple design, the new CLICK PLUS PLCs offer the same practical control but with some surprising bells and whistles. Using the same FREE, streamlined PLC programming software as its predecessor, the CLICK PLUS PLCs provide no-headache programming combined with advanced capabilities like Wi-Fi communication and data logging. The Click and Click PLUS PLC series can be found at this URL: https://accautomation.ca/series/click-plc/ There are several reasons why we are using the Click and Click PLUS PLCs. Here are just a few. - Investment is low for the hardware and the software is free - Standalone PLC with built-in I/O - Communication ability - Ethernet Port, RS232, RS485 - support for protocols such as Modbus RTU, Modbus TCP, etc. - Ability to expand the system with a variety of modules including RTD and Thermocouple inputs directly. https://www.accautomation.ca
