Method for determining synchronization state between clock of field device and clock of reference time transmitter, involves determining synchronization state of characteristic parameters and/or precision time protocol synchronization state

摘要

The method involves adjusting a time displacement of a characteristic tolerance value and/or precision time protocol synchronization value by a user. A synchronization state of a clock of a field device is determined based on a predetermined norm determined. The tolerance and/or synchronization values are provided with the state between the clocks of the field device and a reference time transmitter. Another synchronization state of characteristic parameters and/or precision time protocol synchronization state are determined based on a comparison of the tolerance value with time displacement. Independent claims are also included for the following: (1) an arrangement for determining a synchronization state between a clock of a field device of a process automation technique and a clock of a reference time transmitter (2) a field device (3) a computer program product having a set of instructions for performing a method for determining a synchronization state between a clock of a field device of a process automation technique and a clock of a reference time transmitter for use during a calibration of a field device.
