how to solve communication speed too slow

[zhuzhuzizi]

Hi everyone,

I try to make an automation code to manipulate a machine. But the problem we have now is that, every command need 1s interval to execute the next command. 

This is strange. Because  for read function, the speed is fast. But after reading all the outcome, the machine need 1s to play the next write command. If we reduce the time.sleep() to less than 1, the machine will return X15. Do you have some idea why this situation happen and how to reduce the communication speed?

Below is the simplified code. Thanks for all your help in advance!😊

What NI hardware are you using here?

Serial speeds are often dependent on the device you are communicating with.  I've had some that needed 50ms between commands.  Others will take a constant stream of commands.  I once dealt with an oscilloscope that needed 500ms to 1 second delays between commands so that it had time to perform the command or it would get interrupted.

So any information you can give us about the device you are trying to communicate with would be helpful.

sorry, acutually no. I find that people in this forum very likely encounter similar issue before, so I posted here.

The device is Dressler model 1312, which is a plasma generator.
