ALGORITHM BLOCK
8-2
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.
TOT Totalizer Block. This block is used to count an analog input signal.
Features include: Threshold, Up, Down, Wrap, Scale Factor,
Predetermined Count 1 & 2 and Limit Status.
The actual number of function blocks in a database depends upon configuration memory and
the mix of block types.
NOTE Normally, occurrence numbers are compiled in consecutive order (e.g.,
TM1, then TM2, then TM3 etc.). Forcing higher occurrence numbers out
of order uses up memory space.
