Field device maintenance apparatus
First Claim
1. A field device maintenance system, comprising:
- a field device maintenance apparatus that performs maintenance of a field device whose operation contents are defined by a plurality of parameters, wherein the field device maintenance apparatus performs maintenance of the field device by changing a parameter in the field device; and
a manager device,wherein the manager device accepts setting of parameter attribute information including whether or not individual parameters provided in the field device to be maintained are displayable by the field device maintenance apparatus, and accepts input of work instruction information that shows work contents, andwherein the field device maintenance apparatus comprises;
a field device connection unit that communicates with the field device;
a work-information acquisition unit that acquires the parameter attribute information and the work instruction information which are accepted by the manager device;
a display unit that displays one or more of the parameters of the field device depending on whether or not the individual parameters are displayable according to the parameter attribute information;
an operation accepting unit that accepts a changing operation for changing in the field device the one or more of the parameters displayed by the display unit; and
an operation-history-information recording unit that records a history of operations accepted by the operation accepting unit; and
wherein the parameter attribute information includes whether or not the individual parameters are changeable, andwherein the manager device is configured to accept setting of an attribute as changeable only for one or more of the parameters that are set to be displayable, andthe operation accepting unit of the field device maintenance apparatus is configured not to accept the changing operation for one or more of the parameters that are set to be unchangeable.
