最近应用proface AST3001,PLC为西门子PLC244xp,运行中偶尔会出现故障在屏幕的下方显示 RHxx130: No MPI Token ring detected 无法自恢复,由于故障只是偶然出现,复位后就消失了,所以故障原因很难查找。盼高手给指点指点。
找到一个Peculiar Error Message to Driver 其对RHxx130 Error Code 的描述是:The display does not detect the presence of the token ring.Check Baud Rate settings and cable etc...还有一个补充说明该故障信息为:When it connects with the S7-200 series in the network where there is not a master device besides Display,it may be displayed.
When this error is displayed more than three seconds,please reset the display device.
