In Unity Hot Standby, is it possible to copy the project in the Primary to the Standby CPU without using the keypad?

Yes. Unity will allow you to copy the project running in the Primary CPU to the Standby CPU by setting %SW60.5 high. %SW60.5 is the Auto Transfer bit and once set the PLC operating system will control
its operation. The moment the bit is set you'll observe the PLC OS resetting it low. Never force %SW60.5 high as it will but the HSBY into a continious transfer loop.
