Hello Experts. I am facing an issue that MY PLC’s (315T-2DP CPU) SF LED is continuously blinking and I can’t even establish a connection with my PLC to download any program into it. I have attached the project that I am using. Please suggest the solution asap. Is it a hardware problem? It was working fine until I reset it using the attached procedure. Thanks!
