Method for operating field device e.g. volumetric flow meter, in automatic control engineering, involves linking permissible parameters with user role by role-parameter-matrix, where parameters are determined based on user role
Method for operating field device e.g. volumetric flow meter, in automatic control engineering, involves linking permissible parameters with user role by role-parameter-matrix, where parameters are determined based on user role
The method involves inputting password assigned to specific user role, and providing access rights to parameters of field devices (F1-F4) based on the specific user role, where the field devices are connected with computer units (WS1) over a data bus (D1). The specific user role is determined based on the inputted password. Permissible parameters of the field device are released, where the permissible parameters are linked with the specific user role by a role-parameter-matrix (RP). The permissible parameters are determined based on the user role.
