Multilevel alarms configured but disabled for Module 11,03,04 Block 427 FC 177 [1-LI-1067-M]

This message tells you that a DAANG block appears to be configured to support multilevel alarming, but it is disabled.

There are a number of specific parameter values required to make DAANG: Data Acquisition Analog [FC177] blocks work. This message tells you that one or more of the 2nd high, 3rd high, 2nd low and 3rd low alarms are specified by non-zero values of S22, S23, S26 and S27 and that it seems that the extra alarm limits are intended to be in use.

Bit 2 - Value 4 - Multilevel alarming enable:

• 0 = one high level alarm, one low level alarm
• 1 = three high level alarms, three low level alarms

If the alarm differences are configured, and S20 does not have Bit 2 set, we warn you that multilevel alarming is not enabled.

Example:

Multilevel alarms configured but disabled for Module 11,01,04 Block 427 FC 177.

We infer that the second and/or third alarm limits are intended to be used by comparing them (if not zero) to the span of the block. If they are less than or equal to the span, we assume that the the extra alarm status checking might be desired.

This message is likely to show an error in the system configuration. It should be reviewed. The issue raised may be in unused logic or graphics, or have other realities that make it a non-issue.
