I'd like to read/write Fieldpoint channels on the network from a CompactRIO RT controller.
But i'm not able to deploy any VI containing "FP Read" or "FP Write" blocks. An error like this occurs during deploy:
Deploying FP Read (Float Array -IO).vi
Failed to download FP Read (Float Array -IO).vi
LabVIEW: Failed to load shared library FPLVMgr.dll:ialv_service_read_callback_fast:C on RT target device.
LabVIEW: Failed to load shared library FPLVMgr.dll:ialv_read_fast:C on RT target device.
LabVIEW: Failed to load shared library FPLVMgr.dll:ialv_getTagElements:C on RT target device.
I also tried to manually copy FPLVMgr.dll on the device before deploying, but didn't help

Hi SnamProgetti,
for communicatio between cRIO (i.e. RT target) and FP/cFP, try to use Logos protocol trough DataSocket API. Here's a document:
What Are the Different Communication Techniques Using Logos and FieldPoint?
FieldPoint VIs are not supported under RT targets, so you better use Datasocket or, if possible, Modbus I/O server (for 180x Fieldpoints) or shared variables (for cFP RT targets).
Hope this helps,
Best regards,
Fabio
