Description
Mode
None
RO
The revision level of the static data associated with the
function block. The revision value is incremented each
time a static parameter value in the block is changed.
N/A
AUTO
The user description of the intended application of the
block.
None
AUTO
Can be used to identify grouping of blocks. This data is
not checked or processed by the block.
None
AUTO
The identification number of the plant unit.
N/A
AUTO
See MODE Block Parameter in Chater 2 of the
FOUNDATION Fieldbus Design Considerations
Reference Manual, publication RSFBUS-RM001.
E
RO
Reflects the error status associated with the hardware
or software components associated with a block.
Because it is a bitstring, multiple errors can be shown.
OOS
Identifies the virtual slot location of the Logix Block in
this linking device.
AWL
Analog inputs.
AWL
Digital inputs.
AWL
Analog outputs.
AWL
Digital outputs.
N/A
RO
This alert is generated by any change to the static data.
N/A
RO
The block alarm is used for all configuration, hardware,
connection failure or system anomalies in the block.
The cause of the alert is entered in the subcode field.
The first alert to become active will set the Active
status in the Status attribute. As soon as the
Unreported status is cleared by the alert reporting task,
another block alert may be reported without clearing
the Active status, if the subcode has changed.
