Hello friends!
In previous articles, used Visual Studio C# to connect to PLC Keyence via Ethernet port to retrieve Logfile data. Today continues to connect to PLCs without Ethernet ports via the built-in Serial port that PLCs have (or Serial Module). has researched using Visual Studio software and used C# language to connect to PLC Keyence via Ethernet (or RS232/RS485) to store data from PLC registers.
