简介：
问题： PROFIBUS DP-插头从基本单元拔出，“BUS”-指示灯熄灭，PROFIBUS DP故障的标识符不出现在状态显示中。 解答：如果在总线发生故障期间SIMOCODE的故障响应被参数化为“RETAIN STATUS”，那么既不会停止运行也不会在状态显示中指示。如果在这个事件中不期望出现停止运行但需要信息“BUS FAILURE”，那么可以判断灯控制目录中的位228 “BUS ACTIVE”。 条目号:21453825 日期:2006-04-05 QUESTION: If the PROFIBUS DP-plug is withdrawn from the basic unit, the ''BUS''-LED is extinguished; an identifier for PROFIBUS DP failure does not appear in the status display. ANSWER: If the fault response of SIMOCODE during bus failure is parameterized to ''RETAIN STATUS'', neither shutdown nor indication in status display occurs. If a shutdown in this event is not desired but the information ''BUS FAILURE'' is needed, Bit 228 ''BUS ACTIVE'' in lamp control directory can be evaluated. Entry ID:21453825 Date:2005-04-06
