Why Can't I See My cRIO I/O Modules in MAX? Hardware: CompactRIO
Problem: I am able to see my compact RIO (cRIO) under Remote Systems in Measurement & Automation Explorer (MAX). However, when I expand Devices and Interfaces under the cRIO, I can't see my C-series I/O modules. Why can't I see the C-series modules in MAX? Solution: Currently, cRIO modules are not shown in MAX. Most users are used to seeing the National Instruments hardware connected to their computer by referring to Devices and Interfaces in MAX. Because each C-series I/O module interfaces with the FPGA, MAX is not able to determine which C-series modules are inserted into the cRIO chassis. Once you create a cRIO project, LabVIEW will download a personality to the FPGA that detects which modules are inserted in the cRIO chassis. For more information about creating FPGA projects see the exercise in the Related Links section.
A properly configured cRIO will look similar to this picture in MAX:
As of LabVIEW 8.6, you can see your C-Series modules in the Distributed System Manager if you have your cRIO configured in Scan Mode and the I/O Variables are deployed. You can also read and write those I/O Variables. For more information on using the Scan Mode please see the Related Links section.
