Dear colleagues, I am trying to work with Database in PLCNext, I need for my project to develop a database that is loaded in my PLCNext and that I can write and read. Can I develop this with the Redis App available in PLCNext Store? What do you recommend? Is there a development guide for this type of application?
Hello Albert, If you have time and are familiar with C/C++, I would like to recommend you the SQLite DataBase: https://www.plcnext-community.net/en/makersblog-off/368-how-to-use-sqlite-in-a-plcnext-c-project.html As additional Solution you can use the DL-FB: https://www.plcnextstore.com/#/169 or RT-Datalogger: https://github.com/PLCnext/PLCnext_RT_Datalogger Generally the PLC will be used for datalogging and copying the DL-Files (e.g. via FTP) to superordinate process system for data analysis, because the PLCnext SD-Card capacity is limited. If you would like to use the Redis App in PLCNext Store and have additionall questions, you can contact the App-Developer via Button “Contact Developer” (you have to log in to the PLCnext Store). Best Regards Eduard
