These settings determine whether
data will be exchanged between the
specified Unit and the Special I/O
Unit’s allocated words (10 words/
Unit) during cyclic refreshing for Spe-
cial I/O Units.
Turn ON the corresponding bit to dis-
able cyclic refreshing when the Unit
will be refreshed in an interrupt task
by IORF(097), several Special I/O
Units are being used and you don’t
want to extend the cycle time, or the
cycle time is so short that the Special
I/O Unit’s internal processing can’t
keep up.
(Special I/O Units can be refreshed
from the program with IORF(097).)
