• NCDTR(219) can be used in interrupt tasks.
However, do not execute NCDTR(219) in a cyclic task for the same Unit if NCDTR(219) is executed in
an interrupt task. (The same thing applies to IORD(222) and IOWR(223).)
If an attempt is made to execute NCDTR(219) in an interrupt task when it is already being executed
for the same Unit in a cyclic task, it will cause a duplicate refresh error (non-fatal) and A402.13 will
turn ON.
Example Programming
When CIO 0.00 turns ON in the following example, the sequence that is waiting for a command input
from NCDTR(219) is started for task 1 of the Position Control Unit with unit number 3.
