Chapter 3 Feature Set DescriptionFieldPoint FP-1000/1001 User Manual3-6 ©National Instruments CorporationWhen a new I/O module is connected in place of the one that wasremoved, the FP-1000/1001 first verifies that the replacement I/Omodule is compatible with the one that was removed. If the I/O moduleis the same as, or is compatible with, the one removed, theFP-1000/1001 configures the replacement I/O module with itspredecessor’s configuration and output value settings. It also applies theeffects of any commands sent by the host computer while the I/Omodule was missing.If the replacement module is incompatible with the one that wasremoved, the FP-1000/1001 looks at the information stored in theSnapShot. If the SnapShot is enabled and the replacement module iscompatible with the information in the SnapShot, the FP-1000/1001configures the replacement module with the SnapShot configuration.Otherwise, the FP-1000/1001 configures the replacement module tofactory default settings.Table 3-1 shows how modules are configured after HotPnPreplacement.While one or more replacement I/O modules in the bank are beingserviced by the HotPnP feature, the other I/O modules in the bankTable 3-1.
