摘要：
A method of process control within a plant includes providing a first and second field device associated with processing equipment sensing a first and second process parameter respectively. The field devices are communicably coupled to a host computer by a communications path including a shared field communications channel portion (shared communications channel) that terminates at a communications device which includes a processor and memory that implements an adaptive scan period determination algorithm (adaptive scanner) which determines a first scan period for the first field device and a second scan period for the second field device each based on a parameter relevant to a data type of the process parameter or communications used. The host computer monitors operations in the plant using sampled data provided by the communications device including data based on the first and second process parameter at their respective scan periods.
