CONFIGURATION
5.5.4 Algorithm Block Selection
Algorithm blocks can only be placed in a loop compound. The algorithm types
are:
Algorithm Types:
EX
Expression Block. Reference IB-23G602 Section 8.2. This block
evaluates a user specified expression each time it executes. The
result is discrete or floating point depending on the final operation. An
auxiliary result can be used to convert to other data types.
IC
Input Communications Block. Reference IB-23G602 Section 8.3. This
block receives data from an Output Communications Block in another
instrument.
OC
Output Communications Block. Reference IB-23G602 Section 8.4.
This block transmits data to an Input Communications Block in another
instrument.
LN
Linearization Block. Reference IB-23G602 Section 8.5. This block
produces a linearized value of a floating point input.
PA
Process Alarm Block. Reference IB-23G602 Section 8.6. This block
produces a discrete signal to advise of an irregular process condition.
TM
Timer Block. Reference IB-23G602 Section 8.7. This block is used to
perform timing functions such as delayed start/stop or periodic reset.
NM
Notification Message Block. Reference IB-23G602 Section 8.8. This
block sends a message over the ICN and can request a response.
SM
Supervisory Message Block. Reference IB-23G602 Section 8.9. This
block reads, writes, sets, tunes or configures an attribute over the ICN
or internally. When SET is selected, all message destination fields are
disabled except for the Attribute field. To make a connection with SET
enabled, start from the target block and connect to this blocks
SETENTRY (signal flow is actually from this block to the selected
attribute). Like configured list connections, the target attribute can be
assigned an alias; however, it is not used with PC-30. A connection to
SETENTRY is ignored for all message types other than SET.
PAD
Process Alarm Display Block. Reference IB-1800R-APP. This block
produces a discrete signal to advise of an irregular process condition
and provides an alarm display.
