How Many AC500 PLC's I Can Connect through 800xA PLC Connect?
I have around 300 AC500 PLC RTU's and i need to use 800xA PPA as a frontend so i am planning to use PLC Connect . Please Answer the below questions
1.How Many PLC i can Connect through PLC Connect.
2.Whats the best possible solution to connect 300 PLC's(each with 500 tags)
3. Is it possible to Connect through VSAT Communication.
The options in this case are Modbus RTU or Modbus TCP, it depends, of PLC ports options.
for me is better modbus TCP, is easier to install, but you need to have more than one network conexion, in your 800XA system, I would think, is good idea to divide your 300 PLCs in 3 networks, or 4 networks, it depends also of distances between PLCs and 800XA systems.
