Can you tell me if the serial interface RS 485 which the Baelz controller 6590/3 has can send both the PV & SP to a computer for logging purposes ?
(What information is generally sent through the serial interface RS 485 from the controller ? Can the RS 485 send and receive variables ?)
If so can you give me a price for a card to upgrade my Baelz controller 6590/2 to a 6590/3 ?
Also a price for a new Baelz controller 6590/3 ?
Tony
PS

Can the RS 485 send and receive process and setpoint variables ?
