Abstract
During starting of a field device for pressure measurement, flow measurement and/or fill level measurement, which field device including a memory that includes a boot memory region in which a boot function is stored, and an operating memory region in which an operating function is stored, the following steps are carried out: carrying out the boot function; determining whether a memory check of the operating memory region is to be carried out; carrying out a memory check of the operating memory region when it has been determined that a memory check is to be carried out; and carrying out the operating function.
Claims16
A method for starting a field device for at least one of pressure measurement, flow measurement and fill level measurement, the field device including a memory that includes a boot memory region in which a boot function is stored, and an operating memory region in which an operating function is stored, the method comprising the steps of:
- carrying out the boot function;
- determining whether a memory check of the operating memory region is to be carried out;
- carrying out a memory check of the operating memory region when it has been determined that a memory check is to be carried out;
- dispensing with a memory check of the operating memory region if a preceding system start was successful;
- and
- carrying out the operating function.
A computer program for starting a field device for at least one of pressure measurement, flow measurement and fill level measurement, the field device including a memory that includes a boot memory region in which a boot function is stored, and an operating memory region in which an operating function is stored, the computer program when executed by a processor instructs the processor to carry out the steps of:
- carrying out the boot function;
- determining whether a memory check of the operating memory region is to be carried out;
- carrying out a memory check of the operating memory region when it has been determined that a memory check is to be carried out;
- dispensing with a memory check of the operating memory region if a preceding system start was successful;
- and
- carrying out the operating function.
A non-volatile computer-readable medium in which a computer program for starting a field device for at least one of pressure measurement, flow measurement and fill level measurement is stored, the field device including a memory that includes a boot memory region in which a boot function is stored, and an operating memory region in which an operating function is stored, the computer program when executed by a processor instructs the processor to carry out the steps of:
- carrying out the boot function;
- determining whether a memory check of the operating memory region is to be carried out;
- carrying out a memory check of the operating memory region when it has been determined that a memory check is to be carried out;
- dispensing with a memory check of the operating memory region if a preceding system start was successful;
- and
- carrying out the operating function.
A field device for at least one of pressure measurement, flow measurement and fill level measurement, comprising:
- a memory including a boot memory region in which a boot function is stored, and an operating memory region in which an operating function is stored;
- a controller configured for:
- carrying out the boot function;
- determining whether a memory check of the operating memory region is to be carried out;
- carrying out a memory check of the operating memory region when it has been determined that a memory check is to be carried out;
- dispensing with a memory check of the operating memory region if a preceding system start was successful;
- and carrying out the operating function;
- and
- a sensor configured to carry out at least one of pressure measurement, flow measurement and fill level measurement.
