SYSTEM BLOCKS (INSTRUMENT LIBRARY)

System blocks, at the instrument level, contain the overall instrument related
information and functionality that does not logically fall within any loop or
function block. These blocks exist as resources through the System choice on
the Library icon. Only one interface and system event block is supported as
part of the instrument configuration. These blocks are automatically made
available with each instrument. Other system resources at the instrument level
are the loop compound, the configured list and Modbus list blocks as described
below.

IF

Interface Block. Reference IB-23G600 Section 3.3. The Interface
Block edit display, Figure 5-2, is used to specify up to five
independent function block groupings for a database. Loops are
included in a group by specifying the desired group number in each
loop block. The group scan intervals set the rate at which each group
will be executed when the instrument is in the RUN state.

SE

System Event Block. Reference IB-23G600 Section 3.4. This block
stores a configurable number of time stamped event codes for the
diagnostic points and events reported by the data base blocks.
These codes are translated into messages for operator display or
logging.

LP CPD Loop Compound. The loop compound block is a list connected

compound that contains a Loop Block. Any function block placed in
this compound becomes part of the loop block scan group.
Reference IB-23G600 Section 3.5 for information on the loop block.
As a compound, this resource can be saved and loaded for use
elsewhere. Loop library resources are available within this compound.

CL

Configured List. Reference IB-23G600 Section 3.6. This block is
used to define data base attributes to be collected as a foreground list
for a ICN or MSC module block, or as a Modbus list for a MSC
module block or solely to specify data to be included in interface files
(TIF or MIF). List blocks are configured as described in Section 5.8.

ML

Modbus List. Reference IB-23G600 Section 3.7. A Modbus List is
used to specify data that is to be converted into pure Modbus data (a
2-byte positive value). It is connected through a MSC block. List
blocks are configured as described in Section 5.8.
