PM866 - Not able to download the application
I am facing a problem during controller download.(800xA 5.1 Rev D FP 4 RU 3). I have added some communication variable (Data Type : PCC_ComData) and then downloaded to the controller. Then i have removed the PCC (PCC_Com_Drive block) from the motor then try to download that time i am getting an error " Error 9166:N70:HW Connections:The I/O-connections for Application R494086043N70 are not possile to analyze. Cold restart of the application is required: Row 1, Column 0". This error is directing to AC 800M connections. What may be the possible reasons for this error. How to perform a download without cold restart.
Thanks in Advance

It seems to be a common problem that appeared in Version 5.1. If something goes wrong with a program download, the old application continues to work, buit a coldstart is required to get the new application loaded.

You cant. Select "Cold Restart" during download of the application. If your code is written properly then this should not be a significant problem. Some variable values may return to their last cold saved value.
