Software Configuration Problems
The FP-3000 software consists of a number of function blocks that you can
instantiate, or create, from host configuration software. Each function
block represents an input channel, an output channel, or some control
behavior. In addition, each device contains a Resource Block which allows
you to configure certain overall characteristics for the device. All of these
blocks contain parameters, which are values that you can set to configure
things like channel ranges, scaling to engineering units, and failsafe
behavior.
Some problems are generic to all blocks, and some problems occur only
with certain types of blocks. Table F-3 lists problems that can occur in
many types of blocks. Table F-4 lists problems that can occur only in the
resource block.

Problem Solutions
Block will not leave OOS (Out of
Service) mode, and BLOCK_ERR
does not report any errors.
• Make sure you have written a non- OOS mode to the TARGET
mode of the block.
• If this is a function block, make sure you have scheduled
the block to execute. Refer to your configuration software
documentation for information about how to download a
configuration, including a schedule, to a device. Function
blocks must be scheduled to change modes. If you are
using the NI-FBUS Configurator, you can also refer to
Chapter 3,
Example Applications , for information on
downloading a configuration.
• The resource block might be OOS . This would force all
function blocks in that device into OOS mode. Set the
MODE_BLK.TARGET parameter in the resource block to
Auto , and make sure its ACTUAL mode changes to Auto .
You do not need to schedule the resource block to change
its mode.
