Allocation parameters

The allocation of event categories to the event groups is controlled by the allocation
parameters. They reside 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 allocation parameter consists of 32 bits with the following meaning:
• Bit 0: reserved by the Fieldbus Foundation
• Bits 1 to 15: Configurable area; here, a number of predefined diagnostic events can be
allocated irrespective of the group of events they belong to. In this case they are removed
from their group and their bahavior can be configured individually . With Levelflex, the
following parameters can be allocated to the configurable area:
– 941: Echo lost
– 942: In safety distance
• Bits 16 ... 31: Standard area; these bits are permanently allocated to a specific group of
events. If a bit is set to 1, the respective event category is assigned to the group.
The following table represents the default setting of the allocation parameters. In the
default setting there is a unique relationship between the severity of the event and its
category (i.e. its allocation parameter).

In order to change the diagnostic behavior of a group of events, proceed as follows:
1. Open the allocation parameter to which the group is currently allocated.
2. Switch the bit of the group from 1 to 0. In the case of operation via FieldCare this is
done by deactivating the respective checkbox (see the example below).
3. Open the allocation to which the group is to be allocated.
4. Switch the bit of the group from 0 to1. In the case of operation via FieldCare this is
done by activating the respective checkbox (see the example below).
