5-5 Comparison
The comparison function is effective only when the timing hold in operation
mode A is set to normal.
The setting methods of the set values and hysteresis to compare the present
scaled conversion data and the set values are explained below.
The preset set values and hysteresis are effective only when the Unit is set to
comparison mode. The hysteresis is, however, available only if the timing hold is
set to normal. Use the operation mode A set command to change the timing
hold.
Refer to 6-2 Set Value Teaching for the method to obtain the set values from the
teaching operation.
Settings Set the LL, L, H, and HH set values so that these set values are within a range
from –9999 to 9999. The following are the factory-set set values.
LL and L: –9999
H and HH: 9999
Therefore, if the Unit is operated with the factory-set set values, the PASS bit of
the input word will be always ON.
Set the hysteresis to a value between 0001 and 0999 for the LL, L, H, and HH set
values. The factory-set value of the hysteresis is 0001.
