CONTROL OPTIONS
(6) UPAC function
Optional I/O points will be operable through the program for the UPAC option if DIOB is selected.
Optional I/O points will be operable in the same manner if DIOA is selected. Therefore, up to 20 DI
points and 18 DO points will be operable if two DIO expansion cards as options are used and one of the
expansion cards is set to DIOA and the other one is set to DIOB. This means that the operation of up to
31 DI points and 23 DO points will be available to a single FRENIC-VG unit with consideration of the
number of built-in I/O points.
The two DIO expansion cards mounted cannot be both set to DIOA or DIOB. If such settings are made,
