Abstract
Systems and methods for communicating data from field devices to data acquisition systems. In at least some exemplary embodiments, a remote process or field controller may obtain data, and send the data to a data cache only if the data has changed from previously sent data. The data acquisition system may poll the data cache for data. Having the remote process controller send only data that has changed allows the communication channel between the data caching system and the remote process controller to have a bandwidth or throughput lower than what may be needed to support the polling of the data acquisition system.
