Is safety-rated monitored stop available out of the box, or do I need a safety PLC upgrade?

Out of the box — the RA-6500 is TÜV-certified for Cat-3 PLd monitored stop and safe reduced speed. No upgrade needed.

Which teach-pendant protocol — standard Ethernet/IP, or RoboTech's proprietary bus?

Standard Ethernet/IP at 100 Mbit. RoboTech Studio offline-programming licence is included and keyed to the controller serial.
