If you have enabled the SnapShot feature, the FP-1000/1001 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.
HotPnP (Hot Plug and Play)
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.
Note
Do not add or remove terminal bases while power is applied to the bank. An I/O
module can be hot-inserted only if an empty terminal base is already available in the bank.
HotPnP During Power-Up
Upon power-up, the FP-1000/1001 automatically uploads an electronic
data sheet (EDS) from each I/O module in its bank. The FP-1000/1001 then
configures each I/O module in the bank to factory default settings in the
module’s EDS, or stored SnapShot settings if the SnapShot feature is
enabled.
HotPnP During Operation
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).
Inserting New I/O Modules
When a new I/O module is inserted, the FP-1000/1001 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.
