Method for optimizing the parameter setting of power supply parameters of a field device power module

摘要

A method for optimizing the parameter setting of at least one power supply parameter of a field device power module (WA; 4; 4 ') connected to only one field device (FG; 2) having or having an electrical energy source (40; 40') one is connected and by which the one connected field device (FG; 2) is supplied with electrical energy, the at least one energy supply parameter being an energy supply of the field device (FG; 2) by the field device power supply module (WA; 4; ) and wherein the method comprises the following steps: A) operating the system from the field device (FG; 2) and the field device power supply module (WA; 4; 4 ') in an operating phase of the field device (FG; 2); B) automatically varying a parameter setting of at least one power supply parameter of the field device power module (WA; 4; 4 ') relevant to that phase of operation according to predetermined rules and automated monitoring of the operation of the field device (FG; 2); and C) Automated determination of a parameter setting of the at least one varied energy supply parameter, in which a relatively low energy consumption of the field device (FG; 2) and at the same time a safe operation of the field device (FG; 2) can be realized in the relevant operating phase, wherein for determining a parameter setting of a power supply parameter of a period of an operating phase of the field device (FG; 2) or a time duration of a section of an operating phase of the field device (FG; 2) by the field device power supply module (WA; 4; 4 ') a sufficient power supply of the field device ( 2) and measuring the time required for the field device (FG; 2) to pass through the operating phase or the phase of the operating phase, wherein in the case of the field device (FG; higher voltage is required, as parameter setting of the power supply parameter vo n the predetermined time period, a predetermined offset is subtracted, and / or wherein in the case that the field device (FG; 2) requires a lower voltage in a subsequent phase of operation, as a predetermined offset is added to the measured time parameter setting of the power supply parameter.
