江西万年青水泥公司有限公司4号窑建立于1999年,生产线DCS控制系统选用的是Honeywell公司TPS系统,提供标准的MODBUS通讯接口。在设备改造中,引入了第四代步进式篦冷机,篦冷机控制系统采用的西门子S7-300PLC需要接入原有的TPS系统中。由于系统间数据传输量大,原DCS系统扩容难度较大,故选择标准的MODBUS通讯方式连接两个控制系统,并在2011年4月实施了此技术。
No.4 kiln of Jiangxi Wannianqing Cement Co., Ltd. was established in 1999. The DCS control system of Honeywell Company selects the TPS system of Honeywell and provides the standard MODBUS communication interface. In the transformation of equipment, the introduction of the fourth generation of stepper grate cooler, grate cooler control system Siemens S7-300PLC need access to the original TPS system. Due to the large amount of data transmission between systems, the original DCS system is more difficult to expand. Therefore, the standard MODBUS communication method is used to connect two control systems and the technology was implemented in April 2011.
