Function Block Timing
The following tables show the sweep impact times and size information for all supported
function blocks of the CPU.
Sweep Impact Times
The tables show two sweep impact times are shown for each function. An Increment time
is shown for functions that can have variable length inputs (table functions):
Enabled
Sweep impact time (in microseconds) when a function block has
been enabled; power flow to the function block.
Disabled
Sweep impact time (in microseconds) when a function block has
been disabled; no power-flow to function block and/or power-flow
to reset of function block.
Increment
Incremental time (in microseconds/input unit) to add to the base
function time for each addition to the length of an input parameter.
Only applies to table functions that can have varying input lengths
(i.e. Search, Array Moves, etc.).
All timings represent typical execution time. Timings may vary with input and error
conditions. Each timing includes the time to execute one contact, and normal overhead
including a connection with a programmer.
Note Timings listed in previous versions of this manual did not include this overhead.
• For table functions, increment is in units of length specified.
• For bit operation functions, microseconds/bit.
• For data move functions, microseconds/number of bits or words.
• For functions that have an increment value, multiply the increment by (Length –1)
and add that value to the base time to get total instruction time.
Sizes of Timers, Counters, Math Functions, Trig
Functions, Log Functions
The size of a function is the number of bytes consumed in user logic space for each
instance of the function in a ladder diagram application program.
