Abstract:
1. A method of handling errors arising from parameter write messages for a Fieldbus device, said method comprising: detecting a group of said parameter write messages that occur closer together than operator initiated parameter write messages; suppressing a communication of errors arising from said group of parameter write messages or a rejection of a parameter write operation, wherein said rejection results from any of said errors arising from said group of parameter write messages; setting a load-mode indicator ON for said group of parameter write messages, wherein said communication of errors or said rejection of a parameter write operation is suppressed in response to said load-mode indicator being ON, wherein said load-mode indicator is set ON and OFF based on a comparison of the times of occurrence of a current parameter write message and a previous parameter write message with a time interval, and wherein said time interval is less than a time period between said operator initiated parameter write messages.
