  • Page 10: Device Description

    The Profibus module is designed for installation in constant temperature equipment that supports the Profibus interface. The Profibus interface allows the user to activate constant temperature equipment via the LAUDA command set (for example, control station). Combining the Profibus interface with an RS 232/485 interface is only permitted in conjunction with the Command remote control, whose RS 232/485 interface can be used independently.
