SCADA Batch是西门子用来解决生产高度柔性化要求的产品,基于ISA88标准,用于批处理过程,但同样适用于离散和连续生产过程,采用程序化配方概念,实现控制与工艺的分开。本文主要讲述了在SCADA Batch使用中,冗余系统的配置。
化工与制药行业有很多批处理工艺,同样在食品、饮料和造纸也有这样的工艺,其处理过程的特点之一就是:如果把不同批次的产品放在一起的话,很难区分哪一批生产的产品;其处理的另一个特点是用同一种设备可以生产出不同的最终产品,从而对设备提出了高度柔性的要求。S88标准为批处理控制提供了柔性的方法,虽然该标准是按批处理过程开发的,它也可适用于连续和离散的过程上,连续过程的例子如水的纯化和媒气获取;离散过程的例子如汽车生产;如果这些的生产过程中需要一定程度的柔性,那么就可以应用S88。
SCADA Batch是西门子用来解决生产高度柔性化要求的产品,基于ISA88标准,用于批处理过程,但同样适用于离散和连续生产过程,采用程序化配方概念,实现控制与工艺的分离。它以WinCC系统为基础,可以适用于CPU300,400系统。
在采用SCADA Batch进行生产控制时,配方的执行依靠Batch进行调度,所以对于Batch控制系统,采用冗余保证其可靠就变得非常重要,下文讲述了SCADA Batch冗余配置实例。

Industrial ial “the system uses the international standard industrial bus. The field controller supports PROFIBUS, FF, MODBUS, can and other countries
International standard fieldbus, PROFIBUS is the most widely used open fieldbus international standard in the world, which is divided into FMS, DP and pa
Level III, DP communication rate can be up to 12MB. PROFIBUS is used to connect distributed i/0 stations, field bus instruments and other intelligent devices.
The communication among process station, operator station and engineer station is realized through the system bus diginets (Industrial Ethernet). user
