Restrictions On Interrupt Function; Restrictions On I/O Allocation - Panasonic FP7 User Manual

(Note 1) When an ""*"" is displayed in the INT column, it indicates that the mode setting switch on the side of
the unit is set to ""Use the interrupt function"".

1.2.3 Restrictions on Interrupt Function

The multi input/output unit can start an interrupt program of the CPU unit using an interrupt
input or counter comparison match flag. The interrupt function can be used within the following
range.

(Note 1) If interrupts occur many times in one scan, the execution of interrupt program has priority, and the
scan time will be longer.
(Note 2) If more than one interrupt activation request is made from the unit, the process will be carried out from
the smallest slot number or the smallest interrupt program number.

1.2.4 Restrictions on I/O Allocation

● Any one of functions allocated to the same I/O number can be used. The inputs that are not
allocated to any functions can be used as general inputs.
● Functions to be allocated are specified on the configuration dialog box of tool software
FPWIN GR7. Allocate used input and output numbers not to be overlapped.
