when the profinet occurred An error ,How to respond to error,halt? or else.

I cant find the configration in rmctool?

The following help topics in RMCTools list the tags available that indicate a lost PROFINET connection:

You can make a condition in the Program Triggers using one of these tags, that starts a user program that properly shuts down the machine.

Thanks for your reply。
for example:

When i use Direct Output 1.0v 100v/s, the profinet lost.If i dont deal with the error, the rmc150 always output 1.0v?

Yes.

I think the rmc150 can add the Function。

When the profinet occur error,the error bits can include this error bit, and in the auto stop configuration , can Configuration the stop mode

I also think a feature like that could be useful. In the meantime, the Program Triggers can be used to properly stop the motion and user programs.
