摘要
S7-200PLC独特的自由口通信方法为解决非标准协议的通讯提供了途径。本文以改造配电房马赛克模拟盘为实例,介绍了该项目中配电房各个断路器、开关信号传输到已有的计算机监控系统中的施耐德PREMIUM系列PLC,S7-200PLC自由口同时与马赛克模拟盘和已建成的计算机监控系统通信,实现了非标准协议的马赛克模拟盘与配电房各个断路器、开关之间的同步,使得系统运行高效、快速、稳定、安全。
The unique free port communication method of S7-200 PLC provides an approach for solving non-standard protocol communication. In the paper, transformation of Mosaic mimic panel in transformer room is adopted as an example for introducing Schneider PREMIUM series PLC that all circuit breaker and switch signals in power distribution rooms of the project are transmitted to. The S7-200PLC free interface can communicate with the mosaic mimic panel and the established computer monitoring system, and synchronize the mosaic mimic panel of nonstandard protocol with disconnectory and switches in power distribution room, so that all systems can operate efficiently, speedily, speedily, steadily and safely.
