The invention relates to a circuit arrangement for establishing compatibility between a field device or an interface device for a field device and a diagnostic system pertaining to a control system, to the output of which the interface device or field device can be connected. The diagnostic system is adapted to send, via the output of the control system, a test signal to the interface device or field device and to emit an error signal when an electrical response at the output of the control system lies outside an expectancy range. The circuit arrangement comprises voltage influencing means for influencing a voltage at the output of the control system. The circuit arrangement is characterized in that the voltage influencing means comprises a controllable power source with which power source a current can be produced for influencing a voltage at the output of the control system, that electronic analyzing and controlling means are present to identify a test signal at the output of the control system, that the analyzing and controlling means are adapted, on identification of a test signal, to instruct the controllable power source to adjust a target voltage at the output of the control system, which target voltage is to be within the expectancy range. Additionally, the invention relates to a corresponding method for establishing compatibility.

A process control system includes one or more field devices positioned in a process control plant and a control module configured to generate control signals for controlling the one or more field devices.

A control module software interface may be configured to define a set of interface parameters based on a strategy type associated with the control strategy of the control module. Each interface parameter of the set of interface parameters may be linked to one of the one or more internal parameters of the control module. Additionally, each interface parameter may be accessible by other control modules and/or other external applications.

A system tag identifying a device of a process control loop is determined/derived from a unique identifier of the device while the loop is communicatively disconnected from a process plant's back-end environment or control room. The system tag may be stored at the device itself or at a proxy that is disposed in the field of the process plant (e.g., at another component of the loop). One or more commissioning activities that include the device are performed in the field using the device's system tag, and at least some of the field commissioning activities may be automatically triggered based on the derivation of system tag. Upon the loop being communicatively connected to the back-end environment of the plant, the device's system tag known to the loop in the field is synchronized with the device's system tag known to the back-end of the process plant.
