PM866 Controller in Fault after Serial Firmware upgrade
I have two PM866K01 Processor Modules, one is working perfectly When I connect it through Serial Com4 to IPConfig. I am able to Set the IP. But same could not be done to the other after the Firmware is upgraded using Serial Firmware Upgrade. I have checked the Serial Cable which is OK. Connecting the controller to PC/Laptop as per the Documented Instructions. Serial Firmware Upgrade utility shows upgrade is successful but when I reset the controller it goes into fault. the F(ault) LED flashes slowly. R(un) LED is constantly ON. I have been through the forum with similar problems. I have connected all the necessary Terminators. Used PuTTy and HyperTerminal which return Checksum Error. Can someone please help me with that? The Firmware version is compatible as it worked for the other controller but that was upgraded using Control Builder. Thanks in Advance.

Your question is not crystal clear, what i understood from your question is that you have upgraded one controller Firmware and IP and it is working.
You are not able to config IP in second controller after firmware upgrade or after firmware upgrade controller is going in fault mode, Please clarify.
Are these controllers are in redundant configuration ?
