有个315 AG10的 CPU 启动一个高压设备时5秒左右就死机。不知道什么原因,换了CPU也没解决问题。

问题补充:
电源我也怀疑过,已经单独接入个霍尼韦尔的24V电源。
PIW320 322是电流控制单元的输出,320 不启动高压时工作是正常的。
最佳答案
很明显是干扰造成的cpu内部数据错误。控制系统和强电设备完全隔离,包括接地,屏蔽,零电位。
那就是干扰引起的呀!,做好屏蔽。接地强电弱电分开。
提问者对于答案的评价:
问题还是没有解决,现在脱开所有端子。单独给CPU用隔离变压器供电或者其他24V供电,高压变压器送电,CPU基本都会死机。我考虑将控制挪出柜子了。
最佳答案作者回复:
你把它拆下来拿回办公室测试。如果还有问题就是cpu的问题。
