A system comprising: an industrial controller configured to control a multitude of field devices (34, 36, 38, 40); the system comprising: a Foundation Fieldbus configured to establish communication between a pneumatic valve as a first field device and the industrial controller; an actuator of the pneumatic valve; a positioner of the pneumatic valve coupled to the actuator and configured to position the actuator, wherein at least a sensor (34, 36, 38, 40) in the first field device is configured to detect a first indication of an undesired condition and to communicate the first indication of an undesired condition to the industrial controller, characterized in that the industrial controller is configured to control a second field device based on the first indication of an undesired condition, and the second field device is configured to provide for redundancy in the operation for the first field device in case of detection of a first indication of an undesired condition communicated to the industrial controller; wherein if the first indication of an undesired condition is a condition of insufficient air pressure at the pneumatic valve; then the first field device is configured to stop from following the instructions of the industrial controller; and a control function block of the industrial controller is configured to use an alternative valve as second field device for redundancy in the operation for the first field device. an industrial controller configured to control a multitude of field devices (34, 36, 38, 40); the system comprising: a Foundation Fieldbus configured to establish communication between a pneumatic valve as a first field device and the industrial controller; an actuator of the pneumatic valve; a positioner of the pneumatic valve coupled to the actuator and configured to position the actuator, wherein at least a sensor (34, 36, 38, 40) in the first field device is configured to detect a first indication of an undesired condition and to communicate the first indication of an undesired condition to the industrial controller, characterized in that the industrial controller is configured to control a second field device based on the first indication of an undesired condition, and the second field device is configured to provide for redundancy in the operation for the first field device in case of detection of a first indication of an undesired condition communicated to the industrial controller; wherein if the first indication of an undesired condition is a condition of insufficient air pressure at the pneumatic valve; then the first field device is configured to stop from following the instructions of the industrial controller; and a control function block of the industrial controller is configured to use an alternative valve as second field device for redundancy in the operation for the first field device. a Foundation Fieldbus configured to establish communication between a pneumatic valve as a first field device and the industrial controller; an actuator of the pneumatic valve; a positioner of the pneumatic valve coupled to the actuator and configured to position the actuator, wherein at least a sensor (34, 36, 38, 40) in the first field device is configured to detect a first indication of an undesired condition and to communicate the first indication of an undesired condition to the industrial controller, characterized in that the industrial controller is configured to control a second field device based on the first indication of an undesired condition, and the second field device is configured to provide for redundancy in the operation for the first field device in case of detection of a first indication of an undesired condition communicated to the industrial controller; wherein if the first indication of an undesired condition is a condition of insufficient air pressure at the pneumatic valve; then the first field device is configured to stop from following the instructions of the industrial controller; and a control function block of the industrial controller is configured to use an alternative valve as second field device for redundancy in the operation for the first field device.
