2-3 Scaled Conversion Data/Comparison Result
Either of the following is stored in the input word.
• Scaled conversion data
• Result of comparison between the set value and the scaled conversion data
Scaled Conversion Data The binary-coded scaled conversion data is stored in the input word allocated to
the Unit.
Comparison Results The comparison result of the value is obtained by comparing the preset HH, H, L,
and LL comparison set values and the scaled conversion data. The following bits
will be turned ON according to the result.
• HH: The HH bit of the input word will be ON if the present scaled conversion
data equals or is greater than the HH set value.
• H: The H bit of the input word will be ON if the present scaled conversion data
equals or is greater than the H set value.
• L: The L bit of the input word will be ON if the present scaled conversion data
equals or is less than the L set value.
• LL: The LL bit of the input word will be ON if the present scaled conversion data
equals or is less than the LL set value.
The PASS bit of the input word will be ON in other cases.
If the Unit is in normal hold mode, the hysteresis of the present scaled conver-
sion data will be effective when any of the above bits is turned OFF.
The following is an example of data comparison. The timing hold is set to normal.

2-4 Teaching
The teaching function is can be set only when the timing hold in operation mode
A is set to normal.
The Programming Console makes it possible to adjust the scaling and set val-
ues preset on the Unit using objects.
Scaling Value Teach When the scaling value teach command is executed, the actual input value can
be set as the X1 or X2.
This allows an easy adjustment of the input error.
