I/O Module Problems
FP-3000 offers diagnostic capabilities to help find problems with the
I/O modules you have plugged in.
Software Configuration Problems
The FP-3000 software consists of a number of function blocks that you can
instantiate, or create, from a host configuration utility. Each function block
represents an input channel, an output channel, or some control behavior.
In addition, the FP-3000 contains a Resource Block which allows you to
configure some overall behavior for the FP-3000. 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 B-3 lists problems that can occur in
many types of blocks. Table B-4 lists problems that can occur only in the
resource block.

I/O Module Problems
Problem Solutions
The green READY LED does
not light when the module is
plugged in.
Make sure the module is firmly seated. Also, make sure the
terminal base is firmly attached to the terminal base on its left.
Look for bent pins on the bottom of the module.
The red LED is lit on an I/O
channel.
• TC module: The thermocouple is not connected or is
broken.
• AI module: The input wires are not connected or are
broken.
• AO module: The module cannot source as much current
as the FP-3000 is requesting. This might be because the
output wires are not connected or broken, or there could
be some other electrical problem.
