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 mod ules into the FieldPoint termin al 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.
Caution To avoid damaging the network module and the terminal bases, make sure that
you do not add or remove terminal bases while power is applied to the bank. An I/Omodule
can be hot-inserted only if an empty terminal base is already available in the bank.
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 might or
might 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.

Number of
Flashes Error Condition
0 (stays lit) Configuration has changed and has not been stored in
static memory.
1Parameter storage of nonvolatile and static parameters
has been lost. Re-enter all stored parameters into the
module. You can do this by re-downloading a saved
configuration over the Fieldbus.
2The FP-3000 detected an error in the terminal bases in
the bank or identified a module in an illegal state. Verify
that the protective cover is on the local bus connector of
the last terminal base and that none of the pins of that
connector are touching or bent. Verify that there are no
more than nine terminal bases in the bank and that no
terminal bases were added to the bank while power was
applied.
