System and method for controlling a custom modular measurement system. An editor may receive user input specifying one or more system definitions, each mapping message based commands, parameters, variables and/or metadata (information) accordant with a control protocol for standalone instruments to functions and data in a programming language, and generates the definitions accordingly, each being useable by a client application to interface with a custom modular measurement system that includes multiple logical instruments via the message based information. At least one of the definitions may be deployed onto the measurement system. A run-time engine of the measurement system may accept a message based command from the application, and call a corresponding function, which may invoke operation of at least one of the logical instruments. The logical instruments may be operated concurrently, including sharing use of a single physical measurement device by at least two of the logical instruments.
