Duplex CPU Systems
The ER Flag will turn ON if
the active and standby CPU
Units cannot be synchronized
for instructions requiring syn-
chronization, including IORF,
DLNK, IORD, IOWR, RXD,
FREAD, and FWRIT. This
does not apply to PID. Write
the program to re-execute
these instructions if the ER
Flag goes ON.
Interrupt tasks are not sup-
ported, but they can be used
as cyclic tasks.
I/O interrupts, scheduled
interrupts, power OFF inter-
rupts, and interrupts from
Inner Boards are not sup-
ported.
Supported in CPU Units with
unit version 1.3 or later.
