about the Count Direction of ULx Count Digital Events.vi

[gongll]

Hello,

 I run this Labview program which is called "ULx Count Digital Events.vi". when I choose "Count Direction" to be "countdown", this data is still rising.

For example:

first, I choose "Count Direction" to be "countup". Set the motion system to move 1000 pulses to the positive direction. the labview program data shows 1000. 

second, Set the motion system to move 500 pulses to the negative direction. The labview program data shows 1500, not 500.

third,  I  choose "Count Direction" to be "countdown".  Set the motion system to move 500 pulses to the negative direction. The labview program data shows 2000.

fourth, Set the motion system to move 500 pulses to the positive direction. The labview program data shows 2500.

So I don't know why no matter how I set the parameters, this count keeps adding up.

Best regards!
