In ABB Control system (System 800xA),AC800M connect is the connectivity between HMI (PPA)and AC800M Controllers type (Eg:PM856/861/864/865/866/891) & PLC Connect is the connectivity between HMI (PPA) and any PLC'S includes third party PLC's as well.
Generally "Connect" in system 800xA is the easy connectivity between System 800xA to any third party control system.
Eg:Freelance Connect,MOD300 Connect ,IEC61850 connect,etc...,
If you purchase system 800xA,so by default AC800M connect is the standardised package.If you go for specific connect then particular license should be purchased.
