problem with log in PM554-TP-ETH
i can't loggin to PM554-tp-eth CPU no more after i changed its ip address. If i do a scan with ip configuration i can see the cpu with all the correct parameter. I set communication setting directly with the scan, but when i try to log in the programm show me always communication error's pop up and i can't see no more the communication parameter in the online menu in codesys.
After i changed ip address, led status on cpu is in this condition: led power green, led run blinking, led error red and for all this procedure i put the cpu in stop mode with its switch.
Where am I doing wrong?

changes to the IP address must be made with the CPU in STOP, for security reasons.
Do not forget after the IP modification with SCAN utility, modify the address in Automation Builder setup and last but not least, after the re-load in to the CPU, create a boot project in Codesys session.
Hope this help you
The issu was: when i changed ip address to CPU, from 192.168.6.X to 192.168.14.X, i had also to add to my pc ip settings the new line 14 that i set for the plc (see attachment)
