基于HONEYWELL EPKS R400.2系统热电联产装置DSA通讯数据中断的探讨与改造

Discussion and Transformation of the DSA Data Interrupt in Congeneration Installations Based on HONEYWELL EPKS R400.2 System

热电公用设备的信号需先进入热电公用和化学水装置的SERVER02,再通过DSA的方式通讯到热电联产装置的SERVER01,两套装置的SERVER连接在不同的交换机上,二者需经过交换机→网线→交换机的方式进行通讯。由于系统版本的限制和满负荷运转,DSA通讯频繁出现瞬时中断,影响了工艺操作及监控。

DSA data of public system in Congeneration installations need to first enter the SERVER02 of congeneration public and chemical water installations, then through the SERVER01 of Congeneration installations. Two sets of device servers connected to a different switch and the two required after switch, cable, switch mode of communication. Due to the limitation of the system version and the full load operation of the system, the DSA communication frequently appeared instantaneous interruption, which affected the process operation and monitoring.
