D LED on PLCNext is flashing Red. I am trying to connect AXL F DI8/1 DO8/1 1H module to my PLC (AXC F 2152). I do not know why it is not working. See attached pic for the output from web-based management. The LEDs on this AXL F DI8/1 DO8/1 1H module: IO → Green, ON D → Red, ON
Okay, the problem is solved. I am leaving this comment here in case another person has the same error. In case an error like this happens, connect to Web-Based Management of your PLC for detailed diagnostic information. „ip.x.x.x/wbm“ → Diagnostics → Localbus Check the error codes for: Diagnostic Status Register:\t0x0284 Diagnostic Parameter Register 1\t0x0c02 Diagnostic Parameter Register 2 To check these codes, download „Axioline F: Diagnostic registers, and error messages“ of your device. In my case, it is AXC F 2152. In the manual, it says that the error code for Diagnostic Parameter Register 1 0x0c02 corresponds to the following: An unconfigured module has been detected. An additional device was added at the end of the physical bus structure after the configuration frame was connected. Then, I realized that even if you do not want to use other modules physically connected to your PLC, you still have to add them under AXIOLINE F in your project. Otherwise, you will get this error indicating that you have devices connected to the physical bus, but they are not defined in your project.
