I use Compact RIO and have several C modus installed. When I right click on FPGA target and select new FPGA IO at the available resource column I got no resource available. I wonder what could be the reason? Basically what I want to do is to create a FPGA IO and assign it to a specific IO channel. When I change the hardware configuration in the future I only need to assign the FPGA IO to different hardware channel so I don't need to change any program. Thanks!
Thanks for your reply. You are right. But LabVIEW also automatically populated all the FPGA IOs in virtual folder. If I want to assign a IO to different channel I have to delete the channel that I want to assign in the virtual folder and the FPGA IO channel then becomes available.
Alternatively, you can do a right-click on the FPGA IO item in the virtual folder and select "Select Resource" to re-bind the FPGA IO to a different physical channel. However, (as you already said) you need to delete an FPGA IO item that is already associated to the channel, since you are only allowed to have a single FPGA IO associate to any given channel.
Can you please help me out regarding the same matter..
under the project explorer I find all my modules and controller.. but when I want to add FPGA IO under a specific module say in slot#1, it says it already contains all FPGA IO resources on this module..
and under MOD1 all i have is Mod1/direction
Mod1/step and Mod1/User LED..
how can I approach digital IO's????
moreover the C series module physically doesnot indicate any LED on..although I have given external power connected motor...software detects but no Leds ON...
mayb I have to enable its drive..whats the process.
And please if u can give me your contact #..
I have attached the image..
controller is NI CRio 9074 and the c series module is NI 9501...
with 9501 its a single axis stepper drive module so i guess only these three things will be available not Digital IO like in others..
thats what I think tell me if I am right..??
now the issue is c series module doesnot show physcally thats its connected...I have to enable its drive how can I do that...
plus when i run example given in help (Veloity Control (open loop)- NI 9501).it shows alot of break points..how to get rid of them??
beacuse I donot know the programing through FPGA at this stage. how can i just run exmple drctly
Exactly. You are using the 9501, and those are the only things you need anyways.
I am not sure how that particular module functions. I would suggest you have a look at the user manual for that module to get it to work.
okay so can you please tell me y i am getting errors in the examples that are build in when i try to run it under my controller?
or otherwise how can i add my controller instead of the one thats already added in the examples..how do I have to change the IP of existing one?
I have successfully run single motor using the open loop eample.I want to know what i have to do to run multiple motors at the same time??
can you please help me out?
