Abstract

The invention relates to an electronic control device, in which subordinated individual control units (8) for individual control elements (3, 4) such as motors, are provided. Each individual control unit (8) has a separate module (9) with a processor (91) and a program memory (92), in which a number of control functions are stored. The respectively required function can be activated, for instance, by a selector switch (93).

Claims

1. An electronic system for controlling several different devices comprising:

a. a central processing unit;

b. peripheral control elements, each being connected to at least one of said devices; and

c. a peripheral bus interconnecting said central unit and said peripheral control elements, each said peripheral control element comprising;

(i) a connection module connected to said peripheral bus for exchanging messages with said central processing unit;

(ii) a control module connected to said connection module and having a control processing unit, a memory containing an operating system and several control programs, each program being provided to control one of said devices, and a selector switch, said control program being selectively activated by said selector switch;

(iii) first input/output modules coupled to said devices;

(iv) an internal bus for connecting said control module to said first input/output modules; and

(v) second input/output devices connected directly to said connection module.

2. The control system according to claim 1, wherein said periphery bus and said internal bus are mechanically and electronically independent from each other.

3. The control device according to claim 1, wherein said control module further comprises a separate voltage supply.
