Storing a Custom Power-Up Configuration
Setting a Power-Up State with the Snapshot Feature
The Snapshot feature stores the current state of the Compact FieldPoint
hardware for use as the power-up state of the system.
Caution
Using the Snapshot feature overwrites any power-up values you have specified
for individual channels.
Refer to the
Measurement & Automation Explorer Help for FieldPoint
for
information about using the Snapshot feature.
Configurable Power-Up States
With the configurable power-up state feature, you can define the power-up
configuration on a module-by-module basis. You do not need to set any of
the channels to the desired power-up state as you would with the Snapshot
feature. However, you can use configurable power-up states to adjust
previously stored Snapshot information. In this way, you can make
incremental changes to the power-up values of individual channels.
Refer to the
Measurement & Automation Explorer Help for FieldPoint
for
information about using configurable power-up states.
Inserting, Removing, and Replacing I/O Modules
You can remove and insert I/O modules while the system is operating. You
do not need to power down the Compact FieldPoint system. I/O modules
already working in the system remain fully operational and accessible on
the network. Commands sent to a missing module return an error response,
but the cFP-21
xx
stores the commands and applies the effects of the
commands if a suitable replacement module is inserted.
Caution
Do
not
add or remove connector blocks while power is applied to the system.
When you remove an I/O module and insert a new one, the cFP-21
xx
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 cFP-21
xx
configures the replacement I/O module with its
predecessor’s configuration and output value settings.
