Resource Block
5.2.3 Alarm detection
A block alarm will be generated whenever the BLOCK_ERR has an error bit set. The types of
block error for the resource block are defined above (see Table 5-2).
A write alarm is generated whenever the WRITE_LOCK parameter is cleared. The priority of
the write alarm is set in the following parameter:
WRITE_PRI
Alarms are grouped into five levels of priority as shown in Table 5-3.
5.2.4 Status handling
There are no status parameters associated with the resource block.
5.2.5 VCR
The number of configurable VCRs is 19. The parameter is not contained or viewable within
the resource block, but it does apply to all blocks.
5.2.6 Troubleshooting
Refer to Table 5-4 to troubleshoot any problems that you encounter.

Priority description
0 The priority of an alarm condition changes to 0 after the condition that caused the
alarm is corrected.
1 An alarm condition with a priority of 1 is recognized by the system, but is not
reported to the operator.
2 An alarm condition with a priority of 2 is reported to the operator, but does not
require operator attention (such as diagnostics and system alerts).
3–7 Alarm conditions of priority 3 to 7 are advisory alarms of increasing priority.
8–15 Alarm conditions of priority 8 to 15 are critical alarms of increasing priority.
