Ovation系统LC卡对第三方通信操作策略

Strategy of Ovation system in operating third party system through communication by link controller(LC) module

以四川广安发电有限责任公司定排程控系统通信改造为例,介绍了Ovation系统使用Modbus协议,通过LC卡实现第三方系统通信操作的过程。针对Ovation系统LC卡对第三方系统执行通信操作时出现通信地址错误、指令重复发送、操作结果紊乱的问题,分别从Modbus协议地址匹配、LC卡配置和Ovaion系统逻辑组态3个方面,阐述了Ovation系统LC卡实现通信操作设计中应注意的问题和解决办法。

Taking the communication reformation of the periodic blow down program control system in Sichuan Guang' an Power Generation Company Limited as an example,the operation process of Ovation system to use the Modbus protocol to operate the third-party system through communication by the LC module was introduced.Arming at the problems of the Ovation system occurred in communication operation on third-party system by the LC module,which include the communication address error, the repeatedly sent instructions,the disorder operation results and others,considering three aspects(the Modbus protocol address matching,the configuration of the LC module and the logic configuration of Ovation system are included),the problems needing attention and the solutions in communication operation design of Ovation system by LC module were expounded.
