Abstract

Modular automation system and method are disclosed. A central automation device can be constructed and upgraded using one of a plurality of selectable and variously upgradable baseboards. The automation device can be upgraded using one of a plurality of central units which have uniform external dimensions yet differing data processing power and data storage capacities. At least one input/output expansion device can be directly coupled onto the central unit. Each of the selectable baseboards has a field bus connection interface for a standard field bus connection to a decentral input/output unit.

Claims

1. A modular automation system for industrial automation technology, comprising:

a central automation device including a central processing unit and one of a plurality of selectable and variously upgradeable baseboards,

the central automation device being upgraded using one of a plurality of central processing units which have uniform external dimensions yet differing data processing power and data storage capacities, and

at least one input/output expansion device including an input/output expansion module and an input/output terminal block, the input/output expansion device being directly coupled to the central automation device,

wherein each of the selectable baseboards has a field bus connection interface for a standard field bus connection to a decentralized input/output unit,

wherein the central automation device and the at least one input/output expansion device are electrically connected without cable connections via plug connections, the central automation device and the at least one input/output expansion device being directly connected via the plug connections without intervening components therebetween, and

wherein the at least one input/output expansion device of the decentralized input/output unit includes a housing in which at least one input/output expansion module is housed, and a terminal block onto which an I/O module is pluggable within the housing by means of a detachable connection.

2. The automation system as claimed in claim 1, wherein a selected baseboard of the central automation device can be clipped onto a standard DIN rail, wherein the at least one input/output device can also be clipped onto the DIN rail and electrically and mechanically plugged into the selected baseboard.

3. The automation system as claimed in claim 1, wherein each baseboard can be equipped with at least one communication coupler for bus connections.

4. The automation system as claimed in claim 1, wherein decentralized input/output units in each case feature an input/output device with a field bus connection interface, wherein at least one input/output expansion device can be connected to the input/output device.

5. The automation system as claimed in claim 4, wherein the devices of an input/output unit in each case feature a terminal block onto which an I/O module can be plugged in each case.

6. The automation system as claimed in claim 4, wherein the input/output device is connected to an input/output expansion device, and input/output expansion devices are connected to each other, via plug-type connections for carrying signals of an expansion bus.

7. The automation system as claimed in claim 1, wherein components of a decentralized automation device and components of an input/output unit are configured to be electrically connected to each other without cables via plug-type connections.

8. The automation system as claimed in claim 7, wherein the components of the decentralized automation device and the components of the input/output unit additionally are configured to be in each case detachably connected to each other by means of plug-type means and/or snap-in means.

9. The automation system as claimed in claim 2, wherein each baseboard is equipped with at least one communication coupler for bus connections.

10. The automation system as claimed in claim 3, wherein decentralized input/output units in each case feature an input/output device with a field bus connection interface, wherein at least one input/output expansion device can be connected to the input/output device.

11. The automation system as claimed in claim 5, wherein the input/output device is connected to an input/output expansion device, and input/output expansion devices are connected to each other, via plug-type connections for carrying signals of an expansion bus.

12. The automation system as claimed in claim 6, wherein components of a decentralized automation device and all components of an input/output unit are configured to be electrically connected to each other without cables via plug-type connections.

13. A modular automation method for industrial automation technology, comprising:

a) constructing a central automation device to include a central processing unit and at least one of a plurality of selectable and upgradeable baseboards,

b) upgrading the central automation device using one of plural central processing units which have uniform external dimensions yet different data processing power and data storage capacities, and

c) directly coupling at least one input/output expansion device to the central automation device, the at least one input/output expansion device including an input/output expansion module and an input/output terminal block,

wherein each of the selectable baseboards comprises a field bus connection interface used for a standard field bus connection to a decentralized input/output unit,

wherein the central automation device and the at least one input/output expansion device are electrically connected without cable connections wirelessly via plug connections, the central automation device and the at least one input/output expansion device being directly connected via the plug connections without intervening components therebetween, and

wherein the at least one input/output expansion device of the decentralized input/output unit includes a housing in which at least one input/output expansion module is housed, and a terminal block onto which an I/O module is pluggable within the housing by means of a detachable connection.
