you are correct, you need to contact FAGOR for the correct solution for your cnc model. it is a payed solution.
normaly for cnc8055 you will need an external PC to install the agent.
after the instalation you will get a webserver with MTconnect raw data served. any browser can access this webserver and show a table witth all available data.
you can use this as a low cost sample to get the data...but you must write your own html/css/javascript to do what you want.
