The green POWER LED is lit while the FP-1000/1001 is powered up.
This LED indicates that the power supply connected to the
FP-1000/1001 is acceptable, and that the FP-1000/1001 is supplying
power to the I/O modules.
The yellow NETWORK LED is lit during transmissions from the host
computer on the network. This LED indicates that the FP-1000/1001 is
receiving from the network, and that the communication wires to it are
not broken. The NETWORK LED gets brighter as activity on the
network increases.
The yellow ACCESS LED flashes when the FP-1000/1001 or any of the
I/O modules in its bank respond to the host computer. This LED
indicates that a module in the bank was addressed by a correctly
formatted command, and that the module is responding to that
command (either with a success or error response).
The red STATUS LED is lit when the FP-1000/1001 detects a failure.
If STATUS is not lit, the FP-1000/1001 has not detected a failure. The
FP-1000/1001 indicates specific error conditions by flashing STATUS
a specific number of times. Table 3-2 describes the STATUS LED
flashing sequences and the corresponding error condition.
