8.1 ALGORITHM BLOCKS
Function blocks (algorithm blocks that execute the logic) cannot operate independently in the
instrument database. Groups of related function blocks must be organized into loops.
Algorithm blocks are placed in a loop compound. The algorithm block types are:
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.
