回复： How to hold the value from the case struture

[Floyd He]

Hellow,

I am building a programme, in which I applied a case structure. About every 2-3 seconds its status will turns into "true", and there will be a value output. My problem is: how to keep this output value unchanged (hold that value) when the status turns back to"false"? and then change again when next true status come?

Its kind of ergent, hope someone could help. Thanks a lot!

P.S. The progrmme is build using Control and Simulation tooltik (ie in the control and simulation loop)

Best Regards,

Floyd

false的时候不进行数据操作就ok了，你把数据显示放在case里面。
