Checklists
This section provides brief topical checklists.
7.3.1
LEDs
If the LEDs do not display on the
CPU
or the
modules
:
Verify the CPU power input is a minimum of 8 volts dc.
Ensure power is applied to the FB107.
Verify the wiring connections at PWR+ and PWR
.
Verify the wiring connections at the power source.
Test and reseat the terminal blocks.
Verify all module power inputs are adequate.
Verify the input polarity is correct.
Ensure the module is fully seated in the backplane.
Note
:
The Power In+ LED should be the only LED always on. All other
LEDs flash only during communication. A flashing power LED
indicates the FB107 is in power savings mode.
7.3.2
Serial Communications
If you are experiencing troubles with a
serial communications
connection (LOI, EIA-232, or EIA-485):
Ensure that power is applied to the FB107.
Verify the wiring connections at PWR+ and PWR
.
Verify the wiring connections at the power source.
Verify the wiring connections at TX, RX, A, B, and GND. Refer to
Chapter 5, Communications.
Note
:
The Power In+ LED should be the only LED always on. All
other LEDs flash only during communication. A flashing
power LED indicates the FB107 is in power savings mode.
Verify the communication port settings in ROCLINK 800 (
ROC
>
Comm Ports
).
Note
:
You must perform a power re-start to allow ROCLINK 800 to
identify the module.
