Detailed Setup—ISEL Function Block
July 2013
152
Alarms are grouped into five levels of priority, as shown in table 4‐38.
Table 4‐38. ISEL Function Block Alarm Priorities
Priority Number Priority Description
(1)
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 can be recognized by the system. The device monitors the alarm but does not report it
until requested by the host system.
2
An alarm condition with a priority of 2 is reported to the operator, but generally 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.
1. The priority classes “advise” and “critical” have no relationship to Plant Web Alerts.
Block Errors
Table 4‐39 lists conditions reported in the BLOCK_ERR [6] parameter. Conditions in italics are not applicable for the
ISEL block and are provided only for your reference.
Table 4‐39. BLOCK_ERR Conditions
Condition Number Condition Name and Description
0 Other (N/A)
1
Block Configuration Error ‐ If OP_SELECT is not being used, and SELECT_TYPE = 0. This implies OP_SELECT status is good and actual
mode is AUTO.
2 Link Configuration Error (N/A)
3 Simulate Active (N/A)
4 Local Override (N/A)
5 Device Fault State Set (N/A)
6 Device Needs Maintenance Soon (N/A)
7
Input failure/process variable has Bad status ‐ Set if any IN or any DISABLE or OP_SELECT is bad and connected. This means that a
status of BAD NC would not cause an input failure but a status of BAD LUV or BAD no LUV would cause and input failure.
8 Output failure ‐ Set if OUT quality is bad and the Actual mode is not Out of Service.
9 Memory Failure (N/A)
10 Lost Static Data (N/A)
11 Lost NV Data (N/A)
