现场设备PLC是AB的1756-L63,三台上位机System Management Console CIP以太网独立通讯,但在使用过程中,发生三台同时报
1、ncountered following errors while sending unconnected for nhsm.New_ENB_CLX_000.New_BACKPLANE_CLX_000.New_LOGIX5000_CLX_000
2、ExtSTS=0204: Unconnected Send timed out waiting for a response. 3、Failed to open connection <042ef9c0> 4、Message <03285e08> for nhsm.New_ENB_CLX_000.New_BACKPLANE_CLX_000.New_LOGIX5000_CLX_000 timed out 5、Poke transaction <04b75a64> timed out with 1 items not written 之后就一直报
1、ncountered following errors while sending unconnected for nhsm.New_ENB_CLX_000.New_BACKPLANE_CLX_000.New_LOGIX5000_CLX_0002、ExtSTS=0204: Unconnected Send timed out waiting for a response.
重新将二台上位机WindowViewer画面退出,DASABCIP.4通讯停用,再启用,三台画面过会又恢复正常,频率不定,目前查不出原因,请高手帮忙分析一下故障原因。
