<p>An arrangement is disclosed for altering in the field the operating instructions used by an industrial process transmitter to collect, manipulate and transmit output signals representing the state of an industrial process. The arrangement includes an alterable storage device that has a first set of operating instructions stored therein that characterize the operation of the industrial process transmitter. A controller device connected to the alterable storage device is arranged to use the stored instructions to control the industrial process transmitter. A configuration device connectable to the industrial process transmitter, is arranged to accept a second set of operating instructions entered by a user. Upon establishment of the commmunication link between the configuration device and the industrial process transmitter, the configuration device transmits the second set of operating instructions to the industrial process transmitter, where they are stored in the alterable storage device, replacing the first set of operating instructions. The controller device then uses the second set of operating instructions to collect, manipulate and transmit the output signals representing the state of the industrial process. Alternatively, the arrangement can be used to alter in the field functional process routines or instructions that are used in the calculation of a derived output signal from the collected process signals. The functional process routines that are programmmed into the alterable storage device can either replace previously-stored routines or add new functional routines to a previously-stored set.</p> |
