What do you mean by daisy chaining? What protocol is the existing PV800 using to talk to the PLC? If it's Ethernet, I wouldn't expect any trouble at all adding a second one as long as it has a unique IP address.

Hi thanks for the reply im trying to control one plc using two HMI's im also using TCPIP,

i was wondering if a multistate push button would change state on both PV's  (ie change colour green to red..... run to stop) on both PV's when one is pressed?

Yes, as long as they are reading the same state flag from the PLC.

I'd stay away from using "Smart" controls on HMI's though, especially if you are going to have multiple HMI's.  Smart controls are the types of controls ON THE HMI that include steering logic, or specialty logic; like multi-state buttons that index through a bunch of states.
