Struggling with a GE 90-30 system that won't boot up? While able to download the logic, encountering issues when trying to download hardware configuration, with a message indicating a lost connection with the device. The CPU shows EOK, LAN, and STAT lights blinking steadily simultaneously. Tried troubleshooting by resetting, changing CPU, backplane, and power supply, along with pressing the reset button without success. Firmware version also checked. Feeling completely puzzled and seeking any assistance possible.
Are you ensuring that the hardware configuration you are attempting to download matches the physical components in place? It appears that you have a CPU with an ethernet connection and the configuration is attempting to modify the IP address. Once you have downloaded the hardware configuration, you will need to adjust the Machine Edition communication settings to reflect the new IP address. Alternatively, you can opt for serial communications during the hardware configuration download and then switch to ethernet once the setup is complete. It is worth considering that the current hardware configuration may be programmed to load from flash memory after a power loss, potentially causing conflicts with your goals. Have you tried uploading the existing configuration to check for any issues?
The simultaneous blinking of EOK, LAN, and STAT lights could potentially indicate a problem with your LAN connection or module. It's possible that there's an IP conflict, an issue with your Ethernet cable, or perhaps a fault with the LAN port itself. I'd suggest checking your network setup, trying a different Ethernet cable, and if possible, attempting to connect via a different LAN port on your router/switch. It may also be beneficial to check your LAN module in GE 90-30 using the Proficy Machine Edition; it could very well be that the module itself requires replacement or additional configuration. Hope this helps!
It sounds like you've done a comprehensive job troubleshooting so far. Considering the EOK, LAN, and STAT lights are all blinking simultaneously, it alludes to a communication issue. Since you've already changed out your CPU, backplane, and power supply, the problem could lie in your network configuration. Given the error when downloading hardware config, it could be due to some inconsistencies between how the system's set up and the actual configuration on the PLC. This discrepancy might be in the COMMREQ settings. You might want to double-check your network settings and make sure they match the requirements for the PLC's hardware configuration.
