An actuator of a process control device continuously monitors actuator force and records high force values at each position point by continuously executing a routine in a processor of the actuator. The routine includes receiving from a position sensor a current position value indicating a position of a valve element in the valve, and from a force sensor a current force value indicating a force applied by the actuator. The routine also includes retrieving, from a memory device coupled to the processor, a previous force value measured at the current position, and comparing the current force values for the current position with the previous force value for the current position. If the current force value for the current position exceeds the previous force value for the current position, the routine replaces the previous force value for the current position with the current force value for the current position in memory.

Maximum force logging and operational performance prognostics for process control devices

Methods and apparatus of using customizable templates in process control systems are disclosed. An example method includes initializing a first process control device associated with a first protocol based on a template file and a first parameter definition file. The template file includes global variables and associated values. The first parameter definition file defines a relationship between the global variables and first local variables of at least one of the first process control device or the first protocol. The example method also includes initializing a second process control device associated with a second protocol based on the template file and a second parameter definition file. The second parameter definition file defines a relationship between the global variables and second local variables of at least one of the second process control device or the second protocol. The first protocol is different from the second protocol.
