Communication between all components of a system is paramount to the operation of the system as a whole. Instrument control devices make operating large-scale integrated systems more time-efficient, expand their capability and reduce time needed on-condition or in the test facility in general. Small-scale systems also benefit from instrument control devices allowing for faster data acquisition.

PSP and TSP data acquisition systems can communicate with the test facility and can be remotely operated from a control room after installation. Remote control of each component of the system saves one of the most expensive commodities in experimental or production testing: time. ISSI devices can all be operated over a network which also reduces the amount of cabling to be installed during a test. With each device being uniquely identifiable, a large scale PSP/TSP test can be operated on a single computer or by a small data acquisition team.
