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.

Note 1) The I/O numbers in the tables above show offset addresses. I/O numbers actually allocated are based on the
first word number allocated to the unit. Example) If the first word number is 10, the D/A conversion data on
CH0 and the error flag will be WY10 and X100, respectively.

Name
Turns ON when an error is detected.
Turns ON when the output exceeds the
upper limit of output clipping, provided that
the upper and lower limit function is active.
Turns ON when the output drops below the
lower limit of output clipping, provided that
the upper and lower limit function is active.
Do not use.
Name
Set a digital value corresponding to the
analog output.
<Voltage range>
-10 to +10 V: -31,250 to +31,250
0 to +10 or 0 to +5 V: 0 to +31,250
+1 to +5 V: 0 to +25,000
<Current range>
0 to +20 mA: 0 to +31,250
+4 to +20 mA: 0 to +25,000
* Apply a digital value within the set scale if
scale conversion is set.
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.
Do not use.
