Abstract

A control apparatus of an embodiment controls an external device. The control apparatus includes a first storage, a second storage, and a controller. The first storage includes a first area that can store first information for controlling the external device. The second storage stores software that can access the first area. The controller executes the software stored in the second storage. The software identifies a model of the control apparatus and accesses the first area according to an address of the first area in the first storage included in the control apparatus of the model, the address being stored in association with the identified model in a database that stores the model of the control apparatus and the address in association with each other.

Claims

1. A control apparatus that controls an external device, the control apparatus comprising:

a first storage that includes a first area capable of storing first information for controlling the external device;

a second storage that stores software capable of accessing the first area; and

a controller that executes the software stored in the second storage,

wherein the software identifies a model of the control apparatus and accesses the first area according to an address of the first area in the first storage included in the control apparatus of the model, the address being stored in association with the identified model in a database that stores the model of the control apparatus and the address in association with each other.

2. The control apparatus according to claim 1, wherein after startup of the control apparatus, prior to accessing the first area, the software reads the address stored in association with the identified model from the database, writes the address to a predetermined second area of the first storage, and accesses the first area according to the address stored in the second area.

3. The control apparatus according to claim 1, wherein

the first storage includes a plurality of first areas provided for respective types of the first information,

the database stores addresses of the first areas in association with the models of the control apparatus, the addresses corresponding to the respective types of the first information, and

the software accesses the first area according to the address which is stored in association with the identified model and which corresponds to the types of the first information at least written or read by an access to the first area in the database.

4. The control apparatus according to claim 1, wherein the software receives second information from a host device and identifies the model of the control apparatus based on the received second information, the second information being information capable of identifying the model of the control apparatus.
