Removing Modules from the cDAQ Controller
Complete the following steps to remove a C Series module from the cDAQ controller.
1.
Make sure that no I/O-side power is connected to the module. If the controller is in a
nonhazardous location, the controller power can be on when you remove modules.
2.
Squeeze the latches on both sides of the module and pull the module out of the controller.
