I can log into the PLC online, but I receive this error when making changes and during transmission. A connection via ANLS is required for the transmission to be carried out properly.
You should have already set up an ANSL connection. This is actually the modern connection if you are using a current CPU and a current Automation Runtime.
Presumably the connection simply breaks off when you transfer your project. There are of course a number of errors that are possible. The reason for the termination should also be described in the logbook. Probably a page fault or a cycle time violation ?
mappMotion also requires special download settings
Are we talking about a real PLC or an ArSim? In the latter case, it is easier to use an ‘offline’ project installation.
Dear Administrator, I did these, yes, PC PVI Manager is shutting down.
Try adding /INA=0 to the Extra CPU settings in the online settings view. This column may need to be added to the view. This setting will force the connection to be ANSL instead of INA. Restarting PVI and/or your computer may fix it temporarily but this modification will make sure it will not happen again on that connection.

To be honest, ever since there is an ANSL connection in AS, I notice this behavior once in a while.
Right now, I was struggling with a X20CP1381 that out of a sudden would only connect with INA. Normally in such a case, I restart the AS and am back with ANSL. But not today. Also restarting the PLC and the computer running the AS did not help.
No idea whether or how this is related, but after doing the following, I got an ANSL connection again:
I opened another AS project that by default connects to a different PLC. To this PLC I got an ANSL connection. Then from this project I connected to “my” PLC and it did, using ANSL. Switching back to my actual project I ended up with a working ANSL connection.
I always somehow get this problem solved, but I still think this is some kind of bug in AS (in this case AS4.12).
