工厂级(上层、管理层)包括工厂信息管理和生产管理,负责与工厂管理计算机的连接,计算机间的管理数据交换通过工厂主干网实现。主干网采用ISO/OSI-MAP/TOP或TCP/IP-Ethernet网络协议标准。随着工厂自动化规模的不断扩大,这一级的功能也越来越强,它是DCS 向CIPS 发展的一个重要标志。
车间级(中层、监控层)包括过程控制和过程管理,用于控制室、现场控制设备和各现场控制装置间的连接。通信网采用中速、载带工业过程数据公路的形式(ProwayC或IEEE802.4)。这是DCS的实时工业控制网络,应具有高可靠性、高使用性、实时性强、有自诊断功能、有自组态功能、容易接入新站等。
现场级(低层)用于连接过程控制中的传感器、执行器、智能仪表等。现场以标准的现场总线为发展目标,现已有了两个国际组织的现场总线产品,现场总线将是DCS 发展的一个重要方向。
