Select the Apply the same spec as TO-2047 to T2048-4095 Option to ensure
consistent operation when using the timer numbers allocated by default to
function block variables (T3072 to T4095).
Use the following equation to calculate the number of program steps when
function block definitions have been created and the instances copied into the
user program using CS/CJ-series CPU Units with unit version 3.0 or later.
Number of steps
= Number of instances × (Call part size m + I/O parameter transfer part size n × Num-
ber of parameters) + Number of instruction steps in the function block definition p
(See note.)
The number of instruction steps in the function block definition (p) will not be
diminished in subsequence instances when the same function block definition
is copied to multiple locations (i.e., for multiple instances). Therefore, in the
above equation, the number of instances is not multiplied by the number of
instruction steps in the function block definition (p).
