alarm on the I/O module in slot 2. Note that the screen below the FB107
image provides additional information on the alerts or alarms.
Situations that could cause integrity alerts include:
Communications failures: A module has failed or has been
removed.
: This error occurs on I/O modules and MCS modules.
Note
Module mismatch: The CPU expected to see one kind of module
and you actually installed another.
I/O points are out of range: For example, the AI point default A/D
counts are 643 to 3220. If the AI is open and the FB107 reads 0 A/D
counts, the FB107 generates an integrity alert.
Integrity alerts are typically related to hardware. Alarms are typically
related to user-defined configurations.
For more information on the FB107 GUI, refer to the ROCLINK 800
Configuration Software User Manual (for FloBoss 107) (Form A6217).
This section provides brief topical checklists.
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.
: The Power In+ LED should be the only LED always on. All other
Note
LEDs flash only during communication.
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.
