监控S120的报警了，出错信息：S120_CU320_2:AINF_02 Error 1910:PROFIBUS:setpoint timeout
什么原因造成的
我的配置是 tcpu+cu320+alm+s120，有没有遇到这种情况的
最佳答案
故障 F01910 —— PROFIBUS Setpoint timeout
原因：
The receipt of setpoints from the PROFIBUS interface is interrupted because the bus connection is interrupted or the
PROFIBUS master is switched off or was set to the STOP state.
处理措施：
Restore the bus connection and set the PROFIBUS master to RUN.
