Abstract: An automation device is disclosed, in which a multiplicity of physically distributed functional units communicate with each other by means of a common transmission protocol. The device has a microcontroller (110), which has a group of associated input/output connections which are connected to a resistor network. The resistances of the resistors follow a sequence, the resistance respectively being doubled from the less significant to the next most significant bit. Each input/output connection is actively switched to the associated logic level in order to output a first logic state and is connected as a high-impedance input in order to output the inverse, second logic state.

Abstract: An apparatus and process for monitoring conditions of a control valve including a valve element operated by a drive controlled by a position controller. A spindle extends into a valve chamber through a dynamic seal and connects the valve element to the drive. The condition of the seal is monitored by measuring start-up time, stopping time and distance travelled. The start-up time relates to the time between application of control current to the position controller and sensing movement of the valve element. The stopping time relates to the interval between application of a second control current to the position controller and sensing the valve element has stopped. The distance travelled relates to distance the valve clement travels during the stopping time. A time difference is determined by subtracting the stopping from the starting time and is calibrated to a seal coefficient of friction. The distance travelled is also calibrated to a seal coefficient of friction.
