Note 3 The minimum resolution (accuracy) of the step timer of the Timer block
(Block Model 205), ON/OFF Timer block (Block Model 206), and the Step
Ladder Program block (Block Model 301) is the same as the operation cycle
set to ITEM004.
Even if data connections are made between function blocks having different
operation cycles, the inputs and outputs of each function block are refreshed
according to the operation cycle of the self node.

cycle: a sec.
Note For example, if the output of function blocks having an operation cycle of 0.1
seconds is connected to function blocks having an operation cycle of one
second, the 1-second function blocks accept data after 10 operations of the
0.1 second function blocks.
Even if the operation cycles are synchronized, the order of operation of the
function blocks does not necessarily match the connection order in the
software wiring. (In the above example, function block B does not necessarily
follow function block A.) For details, see 3-2-9 Order of Operations below.

In the figure on the left, block A updates
and outputs analog signals at an operation
cycle of a seconds, whereas block B inputs
the analog signals at an operation cycle of
b seconds.
