1) This event can be removed from the group and treated separately; see the "Configurable area" section.
14.7.2 Assignment parameters
Event categories are assigned to the event groups via four assignment parameters. These
are located in the RESOURCE Block (RB2):
• FD_FAIL_MAP: For the "Failure (F)" event category
• FD_CHECK_MAP: For the Function Check (C) event category
• FD_OFFSPEC_MAP: For the Out of Specification (S) event category
• FD_MAINT_MAP: For the "Maintenance required (M)" event category
Each of these parameters consists of 32 bits with the following meaning:
• Bit 0: Reserved by the Fieldbus Foundation
• Bits 1-15:
Configurable area; certain diagnostic events can be assigned independently of the event
group they belong to. They are then removed from the event group and their behavior
can be configured individually. The following parameters can be assigned to the
configurable area of this device:
• 042:
Sensor corrosion
• 103:
Drift
• 901:
Ambient temperature too low
• 902:
Ambient temperature too high
• Bits 16-31: standard range; these bits are permanently assigned to the event groups. If
the bit is set to 1, this event group is assigned to the individual event category.
The following table indicates the default setting of the assignment parameters. In the
default setting, there is a clear assignment between the event weighting and the event
category (i.e. the assignment parameter).
