Thank you for responding. We had replaced the motherboard and was able to boot the KPC and had restored the communication between the KPC and Smartpad.
After the KPC boots up we encountered the below Error. (Shall i transfer this topic to a different thread or is it okay to post it here ?)
“<SYS-X44> Error during ECat stack initialization. Device: EL6731 PROFIBUS DP Master [Init command failed – PREOP to SAFEO]”
