Abstract
A process control system includes an executive routine located at a first node of a process control system, one or more soft phases located at other nodes remote from the first node and communication software located in the each of the nodes to enable the executive routine to call and execute the soft phases that are at nodes remote from the first node. This operation may reduce loading or communication traffic on the batch executive node and enables the operator to interact with a soft phase at a workstation or node that is convenient to the operation of the soft phase, which makes the operator's task easier and results in faster execution of the soft phase.
