Apparatus and method for controlling and/or monitoring a technical installation for producing and/or processing metal, having an assistant program with at least one interface for connection to application programs, wherein the assistant program receives a request for an item of information relating to the installation from at least one requesting application program via the interface, wherein the assistant program can access a data model that provides a suggestion of which information can be provided by at least one further application program. The assistant program determining, based on the request and on the data model, which application program can provide the requested information, wherein the assistant program transmits the request to the at least one determined application program which can provide the requested information, wherein the assistant program receives a response from the determined application program, and wherein the assistant program outputs the received response to the requesting application program.

Apparatus for controlling and/or monitoring a technical installation

A control device () for a roll stand (). During rolling of a metal strip () in the roll stand (), the device receives measurement data (M) for a lateral position (y) of the metal strip () on the inlet side and/or outlet side of the roll stand (). Taking into account parameters (P) of the stand regulator () on the basis of the deviation in the lateral position (y) from a target position (y*), a stand regulator () of the control device () determines a tilt value (δs) for the roll stand () and controls the roll stand () accordingly. The control device () determines at least one variable (V, V, Q, Q) from which it is derived, for both strip edges () of the metal strip (), whether the metal strip () forms an undulation () in the region of the particular strip edge (). As soon as the metal strip () forms an undulation () in the region of one of the strip edges (), the control device () varies at least one of the parameters (P) of the stand regulator (), such that the stand regulator () determines the tilt value (δs), starting from the variation in the at least one parameter (P), and taking into account the changed parameter (P).
