MASKING THE INFLUENCE OF UNSUPPORTED FIELDBUS COMMANDS

摘要

A control or test system for a field device includes: a communication unit for bidirectionally commmunicating with the field device via a fieldbus protocol; a command memory for receiving commands that are transmittable to the field device via the fieldbus protocol; and a masking memory, which masking memory receives the commands contained in the command memory that are not supported by the field device, and/or receives an error message returned by the field device in response to such command.
