Panasonic AFP7DA4H - Confirming the I;O Number Allocations and First Word Number; Occupied I;O Area and I;O Allocations

4.1 Confirming the I/O Number Allocations and First Word Number
4.1.1 Occupied I/O Area and I/O Allocations
In the FP7, digital data for analog output is allocated to the external output relay area and
processed. Furthermore, control I/O signals are allocated to the FP7 to process errors and clip
upper and lower output limits.

Turns ON when the output exceeds
the upper limit of output clipping,
provided that the upper and lower
limit function is active.

Lower limit of
upper and lower
output clipping
Turns ON when the output drops
below the lower limit of output
clipping, provided that the upper
and lower limit function is active.

Upper and lower
limit output
clipping function
execution relay
The upper and lower output limit
clipping function is executed with
the relay turned ON.
With the relay turned OFF,
the upper limit flag (Xn1) for upper
and lower output clipping limits
and the lower limit flag (Xn2) for
upper and lower output clipping
limits are turned OFF.
