Inserting New I/O Modules
When a new I/O module is inserted, the FP-1600 automatically uploads
the EDS and configures the I/O module to factory default settings in the
module's EDS, or to stored SnapShot settings if the SnapShot feature is
enabled. This configuration is accomplished without any intervention from
the host computer or software.
Replacing I/O Modules
When an I/O module is removed, the FP-1600 does not undertake any
special course of action for the bank. The host computer (or the software
executing on it) could be unaware that the I/O module is missing, and might
continue to send commands to the missing I/O module. Each command
returns an error response, but the FP-1600 remembers the commands sent
to the missing I/O module.
When a new I/O module is connected in place of the one that was removed,
the FP-1600 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-1600 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-1600 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-1600 configures the replacement
module with the SnapShot configuration. Otherwise, the FP-1600
configures the replacement module to factory default settings.
Table 4-1 shows how modules are configured after HotPnP replacement.
