Problems solved by technology

Compared with large-scale automation systems, small-scale automation systems have relatively simple automatic measurement and control requirements and lower precision. If the field bus automatic control scheme and equipment configuration of large hydropower stations are directly applied, it will result in complex models, high costs, and large equipment footprints. , Serious waste of functions, etc.

Abstract

The invention discloses an SKW real control network field bus, which comprises a master machine and one to fifteen slave machines, wherein serial ports are formed on the master machine; and the master machine is connected with the slave machines through the serial ports. The SKW real control network field bus is simple in structure, lower in cost, small in occupation space of equipment, high in functional utilization ratio, and quite applicable to a field control unit of a small hydropower station or other industrial automatic systems.

Description

technical field [0001] The invention relates to a field bus of an SKW real control network, in particular to a field bus suitable for small hydropower stations or other small industrial automation systems. Background technique [0002] Countries all over the world are fiercely competing for fieldbus. Those with market share, such as CAN, LONWORKS, FF, PROFIBUS, etc., are suitable for building large systems (such as large hydropower stations). For small hydropower stations or other small automation systems, their cost performance is very low. Compared with large-scale automation systems, small-scale automation systems have relatively simple automatic measurement and control requirements and relatively lower precision. If the fieldbus automatic control scheme and equipment configuration of large hydropower stations are directly applied, it will result in complex models, high costs, and large equipment footprints. , Serious waste of functions and other problems.
