涡流探伤中PLC监控软件的设计

摘要

利用Visual Basic为平台，开发了一套PLC上位监控软件，实现了PC上位机和PLC的通讯连接，并成功用于涡流探伤监控系统中。该监控软件简便易用，人机交互性强，能够及时地更新显示监控信息。%We developed a PLC host monitoring software kit with Visual Basic as a platform and realized the communications between a PC and a PLC. The monitoring software is also applied to an eddy current test system. It has better human-computer interaction and can update information promptly.
