updata speed of reading postion value

[jimmyjimmy2000]

I have some prolem in getting postion value with 7344 in order to get the Bold Diagram. I have tried highspeed capture function in such way:first enable hs,and then read_hs_pos_return. Is this way of using the function correctly.if so, is there any other way to get the postion value more quickly?

This sounds like the correct procedure. High speed capture will work up to apporximately 100Hz. How fast are you trying to trigger?

My system should be working at a frequency of about 300Hz .Can you provide me any other solution about my object. Thanks.

Thank you for your answer.:)
In addition, i want to know , if there is any way to trigger the axis motion at high frequence.
In my system ,one computer takes the charge of computing motion track, and the other one takes the charge of trigger the axis motion with 7344, the track signal is transfered via RS232 cabel. The track-computing computer sends message at the frequence of about 300Hz.
Maybe we need other devices to macth our requests ,can you prvide me a solution. Thank you
