You're getting it right if that pattern of Decentral control? dotted lines and knobs looks anything like a decentral deployment of structural In control in components to you, where any one component is connected to all others. Even any way. a simple image such as this clearly illustrates that locally installed nodes linked in a decentral network can resort to a different structure for communications than nodes that just stand by to follow orders in a centralized implementation.

■■ Application performance

An automation concept can follow a central or a decentral approach. The choice either way is determined by the degree to which the network needs to enable control of deterministic process timing. As the »degree of hardness« of real-time requirements increases, decentral layouts are preferred over central control schemes. However, as it turns out, there is no clear-cut differentiation between centralized and decentral-style automation concepts: any centralization concept also includes decentral structures, and all decentral concepts also have centralized portions. The basic difference lies in the extent of the tasks the control system will assign. In a centralized installation, the controller only doles out »snippets of work« to the components involved, whereas a decentral concept will have these same components taking care of tasks as a whole. Decentralization ETHERNET POWERLINK PRODUCT NEWS 5 The Magazine for the Standard FACTS in Industrial Ethernet

The drive controller has to handle a whole range of tasks: a profile genera- tor has to calculate the axis accelera- tion for every cycle, a rotor position controller registers and adjusts the axis position, another controller regu- lates the rotational frequency and therefore the speed of a movement, and a current controller determines the moment of force or torque of the motion performed. These calculations can be made in one of two places – either within the drive itself, given that it has sufficient integrated computing power, or in a central controller that takes on these tasks. Calculations on the part of a central controller obviously require great bus bandwidth, and, if several axes have to be con- trolled, enormous computing power in the controller. It is also apparent that even for a small number of axes there is a large amount of data that has to be processed, which takes its toll on speed in any case. The Master, i.e. the controller, would have to perform all calculations and transmit them to the Slave, i.e. the drive, which in turn would have to provide continuous live feedback on its status. Hence, the control loop would be closed via the bus, which would make the applica- tion's functionality more likely to be compromised. Also, modern servo axes are clocked at 16,000 Hz. Providing the necessary computing power to control them in an external therefore means that central values reported by the sensors on controlled and coordinated, decentral unit is practically impossible. controllers are relieved of some temperatures, fill levels and other control concepts lend themselves as load as jobs are outsourced to and parameters, and checking them the preferable alternative.

FACT 2: FAVORABLE OPENNESS The open Standard – no dependence on proprietary ASIC systems

POWERLINK provides the only real-time Ethernet standard in the true sense of the word – a software solution that relies on standard hardware components and fully standard-compliant Ethernet frames. It is not without reason that its user organization is called »Ethernet Powerlink Standardization 2 Group«. www.ethernet-powerlink.org FR&P MM-E00745.598 Powerlink Facts Herbst 2007 englisch Facts Herbst Powerlink 2007 MM-E00745.598
