What does it mean when the status light on the FP-1000 blinks twice?

[Graziano]

From FP 1000 User Manual, page 34,

The FP-1000/1001 has detected an error in the
terminal bases in the bank or has 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.

The manual is at the URL http://www.ni.com/pdf/manuals/370706a.pdf

Hope it helps!

We determined that a module had been wrongly placed.  Thanks.
