My vote is usually for a Ethernet to RS485 converter for all request originating from off location. Use local Ethernet, make anybody who wants to cause trouble go through a serial gateway, worst they can do is lock up a comm port and force somebody to go reset it, (if it isn’t on a auto-reset on comm-fail setup anyway).
Of course AB won’t just use modbus like EVERYONE else… so you have to work at it a bit more.
