Dear All, I have been working on a 414-4H (protection) system. The CPUs are found faulty so we decided to replace them. The firmware for the old CPUs is 4.0.4. We needed two CPUs of firmware 4.0.12. But due to some reasons, we were only able to buy one CPU of firmware 4.0.12. The firmware of second new CPU is 4.0.10. There is another 414-4H (governor) system running in parallel with this 414-4H (protection) system. The CPUs of governor system have firmware 4.0.12. That is why we wanted the same firmware for the CPUs of protection system. Now I have installed the new 4.0.12 CPU as MASTER and 4.0.10 as SLAVE in my protection system. When the supply was turned on, the STOP LED of both CPUs started blinking slowly. When I push the toggle switch the LED flashes with high frequency and then becomes still. So that means the memory is reset. But after a few seconds it starts to flash slowly again. This is the case with both the CPUs. What does this mean? Also I can only download the program in MASTER 4.0.12 CPU when the SLAVE 4.0.10 CPU is off. I believe this is because the firmwares of the CPUs are not the same. So do I need to update firmware 4.0.10 to 4.0.12? What are the steps for that procedure? If by any chance I get another new CPU of firmware 4.0.12, what should be the sequence of installing, resetting and downloading in the CPUs? I have combined the diagnostic buffers of both the CPUs in the same pdf file and attached it here. Regards AttachmentDiagnostic Buffers.pdf (219 Downloads) |
