Can not control NI 9481 in cRIO-9067 with ethercat

[RongweiWen]

Hello,

I have a cRIO-9067, NI 9481 and third-party devices (Delta servo motor dirvers) as follows. The drivers are controlled by ethercat in a daisy chain. I use NI 9481 to control the brake of motors.

I wirte a project attached and as follows. The control9481.vi is used to control 9481 only. The SDI Axis Straight Line.vi is used to control four servo motors only.

But I found that once I run SDI Axis Straight Line.vi, the control9481.vi cannot control NI 9481.

If I format the cRIO-9067 and reinstall all software. Without run SDI Axis Straight Line.vi, the control9481.vi can control NI 9481 normally. Then I run SDI Axis Straight Line.vi, it can also control motors normally. But after running SDI Axis Straight Line.vi, control9481.vi will no longer control NI 9481. 

At this time, if I create a new project and search target of cRIO, it give following warning.

If I format cRIO-9067 and reinstall software again. The control9481.vi can control NI 9481 again. But after I run SDI Axis Straight Line.vi, aforementioned phenomena will reappear. It seems there is conflict between these two VIs, or when deploying. I don't know why, can anyone help me.
