CAUTION
Refreshing by the DeviceNet master function is
made asynchronously with the execution of the
ladder program. Therefore, keep the following in
mind when creating a ladder program.
<1> When a DeviceNet input signal set in the
specified PMC address is read from two
points in the ladder program, even if the
ladder program can be executed in one
cycle, there is no guarantee that the same
value can be read.
<2> When the ladder program writes an output
signal to DeviceNet in the specified PMC
address, the signal may be transferred to a
slave device before the ladder program is
completely executed.
