Note If a Special I/O Unit is not refreshed periodically from the CPU Unit (at least
every 11 seconds), a CPU Unit monitoring error will occur. (The ERH indicator
and RUN indicator will be lit on the Special I/O Unit.) If cyclic I/O refreshing of
a Special I/O Unit is disabled, use the IORF(097) instruction to refresh the
Unit from the user program.
Function
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 Special 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).)
