100 Mbps LED
The green 100 Mbps LED is lit when the cFP-20xx is communicating
at 100 megabits per second. If the 100 Mbps LED is not lit, the cFP-20xx
is communicating at 10 megabits per second.
User-Configurable LEDs A–D
LEDs B, C, and D can be sent values of 0, 1, or 2. LED A should be sent
only 0 or 1. LED A handles a 2 as a 1. The values sent to these LEDs
manifest as 0 = off, 1 = green, and 2 = red.
Power-On Self Test (POST)
The cFP-20xx runs a power-on self test (POST) at power-up to verify its
operational status. The test takes several seconds, does not affect the
operation of the network, and does not affect any of the field wiring on
connector blocks installed on the backplane.
If the power-on self test fails, the cFP-20xx does not participate in network
communication, eliminating potential conflicts with other controllers on
the network.
When you power up the cFP-20xx and it has already been configured for
use, the POWER and STATUS LEDs turn on for about five seconds, then
the STATUS LED turns off. The A, B, C, and D LEDs stay lit for about
15 seconds as LabVIEW RT starts up. When they turn off, the I/O module
READY LEDs turn on and the controller is ready for use.
The cFP-20xx indicates POST failure through the STATUS LED. If the
LEDs do not follow the sequence described here, refer to the STATUS LED
Error Indications section of Appendix A, Troubleshooting, for information
about possible reasons.
