• The hot-swap reporting mode for the FieldPoint stack. Refer to the
next section, HotPnP (Hot Plug and
the hot-swap reporting mode.
If you have enabled the SnapShot feature, the FP-1600 restores your
desired settings to all I/O modules and channels in the bank every time you
power up, until you disable the SnapShot feature.
The HotPnP feature simplifies system installation, configuration, and
maintenance. With the HotPnP feature, you can remove or insert I/O
modules into the FieldPoint terminal bases while power is on, even if the
system is already engaged in network activity. You do not need to power
down the entire system or even a bank to insert, remove, or replace I/O
modules. In addition, you do not need to change the operation of the host
computer or software to use the HotPnP feature.
When you insert an I/O module with the power on, it is automatically
recognized, configured, and made available on the network. The following
sections describe how the HotPnP feature works under different conditions.
On power-up, the FP-1600 automatically uploads an electronic data sheet
(EDS) from each I/O module in its bank. The FP-1600 then configures each
I/O module in the bank to factory default settings in the module's EDS, or
in the stored SnapShot settings if the SnapShot feature is enabled.
You might need to insert or replace one or more I/O modules in a bank
while your system is operational (power is on and the network may or may
not be active).
While one or more new or replacement I/O modules in a bank are being
serviced by the HotPnP feature, the other I/O modules in the bank remain
fully operational and accessible on the network without any interruptions.
As soon as the FP-1600 configures the new or replacement I/O module
through the HotPnP service, that I/O module becomes automatically
accessible on the network.
