When the two PLCs do backup for each other, in order to improve reliability, whether the analog output terminals can be connected in parallel?

The two terminals of analog output can not be connected in parallel. If you want to make a backup, you need to add a toggle switch between the two channels of analog. Use the toggle switch to control the output, while ensuring that there can be only one channel of analog output each time.
