PGM does not synchronize with backup
Diagnostic Check
Primary module cannot synchronize with secondary module.
In the Monitoring view, double-click the primary PGM icon to display the block configuration form.
Click the
Redundancy
tab and check the Inhibit Sync Reason parameter description for not achieving
synchronization.
Troubleshoot to correct condition for inhibiting sync.
Cause 1
Redundancy cable bad.
Solution
Replace redundancy cable. Check if the modules synchronize.
Cause 2
PBLink cables may be disconnected.
Solution
Reconnect cables to the PGM IOTA.
Cause 3
Secondary module bad.
Solution
Replace the module. Check if the modules synchronize.
Cause 4
Backup IOTA bad.
Solution
Replace the IOTA. Reinstall the original secondary module on the new IOTA. Check if modules
synchronize.
Cause 5
Primary module bad.
Solution
Replace primary IOTA. Reinstall the original primary module on the new IOTA. Check if modules
synchronize.
Cause 6
Software problem.
Solution
Contact Honeywell SSC.
Fatal ECC error
The PGM software has detected a fatal Error Checking and Correction (ECC) condition that can be a multiple-
bit error or excessive single-bit errors in the main Random Access Memory (RAM).
Diagnostic
Check
•
The 4-character display on the modules displays FAIL or mMBE.
•
In the Monitoring view, the PGM icon turns red.
Cause
The PGM software has detected a failure that does not allow operation to continue. There can be many
causes for a failure including hardware.
Use the CTools utility to capture diagnostic data for the device to determine the possible cause before
proceeding. If the error occurs in the backup RAM, a fault is indicated. If the error occurs in main RAM,
the module freezes with mMBE on the display.
Solution
Try shorting the reset pads on the IOTA to restart the module. If error persists, replace the module.
Check the Trace log for breadcrumbs that occurred prior to the event. Provide the results of the trace log to
Honeywell Solutions Support Center (SSC) for analysis.
Display shows FAIL
The PGM detects failure during system integrity checks, such as Watch Dog Timer (WDT), error detection
circuits, microprocessor static configuration registers, and Read Only Memory (ROM) checksum.
Diagnostic
Check
•
The 4-character display on the PGM displays FAIL.
•
In the Monitoring view, the PGM icon turns red.
Cause
The PGM software has detected a background diagnostic failure that does not allow operation to
continue.
