National Instruments Corporation
When a new I/O module is connected in place of the one that was
removed, the FP-1000/1001 first verifies that the replacement I/O
module is compatible with the one that was removed. If the I/O module
is the same as, or is compatible with, the one removed, the
FP-1000/1001 configures the replacement I/O module with its
predecessor’s configuration and output value settings. It also applies the
effects of any commands sent by the host computer while the I/O
module was missing.
If the replacement module is incompatible with the one that was
removed, the FP-1000/1001 looks at the information stored in the
SnapShot. If the SnapShot is enabled and the replacement module is
compatible with the information in the SnapShot, the FP-1000/1001
configures the replacement module with the SnapShot configuration.
Otherwise, the FP-1000/1001 configures the replacement module to
factory default settings.
Table 3-1 shows how modules are configured after HotPnP
replacement.
While one or more replacement I/O modules in the bank are being
serviced by the HotPnP feature, the other I/O modules in the bank
