AC800M-HI independent and freelance
how can I use AC800M-HI independent(without 800xA system) in combination with a freelance system?what license should I use for engineering and what for operator station and which communication can be used?
I am not sure what is use case but depending on your requirement/constraints you can communicate over OPC or Modbus, OPC will be easy, cost effective and needs less effort to engineer. You need to reference ac 800m OPC server in freelance system and fetch values from ac 800m.
Another option could be communicating over Modbus but you need communication module at both side, will add hw/license cost and engineering effort.
I do not have idea about license for ac800m-hi usage. for freelance basic license will cover your use of engineering tool (CBF), Operator station (DigiVis) and communication options.
I have never used or seen using this combination but good to get answer from someone already used this combination.
