Abstract: A communication device for control interaction between operating electronics and an actuator to set a process fluid flow of a process-engineering plant can include a first communication interface configured to receive electrical signals from the operating electronics, a second communication interface configured to provide electrical actuator commands to the actuator, and a permissibility processor having a data memory that stores permissible actuator commands, the permissibility processor being configured to cause the second communication interface to provide one of the permissible actuator commands to the actuator based on an electrical signal of the electrical signals received via the first communication interface.

Abstract: A field device that includes a primary valve, a main actuator, a bypass line, a secondary valve, and a position controller. The primary valve can be configured to adjust a process fluid flow. The main actuator can be configured to control the primary valve. The main actuator includes a working chamber to be subjected with a process fluid and a return device configured to bias the valve member. The bypass line can be configured to fluidly connect an inlet and an outlet of the primary valve to feed the process fluid to the working chamber. The position controller configured to control a pneumatic actuator to control the secondary valve to change a process fluid pressure in the working chamber. The controlling of the pneumatic actuator can include generating a pneumatic control signal based on a position of the primary valve and supplying the pneumatic control signal to the pneumatic actuator.
