Assignment parameters

Event categories are assigned to the event groups via four assignment parameters. These
are located in the RESOURCE (RB2) Block:
• 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 to 15: Configurable area; certain diagnostic events can be assigned here
independently of the event group they belong to. They are then removed from the event
group and their behavior can be configured individually.
In the Levelflex the following parameters can be assigned to the configurable area:
• 941: Lost echo
• 942: In safety distance
• 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).

Proceed as follows to change the diagnostic behavior of an event group:
1. Open the assignment parameter in which the group is currently assigned.
2. Change the event group bit from 1 to 0. When operating via FieldCare, this is done by
unchecking the corresponding check box (see the next example).
3. Open the assignment parameter to which the group should be assigned.
4. Change the event group bit from 0 to 1. When operating via FieldCare, this is done by
checking the corresponding check box (see the next example).
Example
The Highest weighting / configuration error group contains the events 410: Data
transfer, 411: Upload/download, 435: Linearization and 437: Configuration
