Alarms displayed by DEVICE_STATUS_1 to DEVICE_STATUS_8 resource block parameters
in their default setting are categorized as described in “NAMUR NE-107 Alarm Categories”
in the DEVICE_STATUS table in section 8.1. When an alarm occurs, a character string that
corresponds to an alarm category is assigned to FD_*_ACTIVE (index 1067 to 1070) [* indicates
FAIL, OFF SPEC, MAINT or CHECK]. (For example, an F category alarm is assigned to FD_
FAIL_ACTIVE) Similarly, procedures for processing alarms are assigned to FD_RECOMMEN_
ACT. For details on alarm displays and how to deal with them, refer to Table 6.2.
