Upper limit
The transferred count value is then compared with the upper and lower limits
of a set of ranges which have been preset in DM 00 through DM 31. If the
current value is within any of the preset ranges, the corresponding bit of the
results word, R, is turned ON. The bit in the result word will remain ON until
the current value is no longer within the specified range.
When the reset input (1804) goes ON, the present value is cleared to 0000,
even if the start input is OFF, and all bits in R are set.
high-speed counter, use HDM(61).
When using the counter, the following bits are reserved and cannot be used
for any other purpose:
If a power failure occurs, the count value of the counter immediately before
the power failure is retained.
The following table shows the upper and lower limits that need to be set in
DM 00 through DM 31. In this table, S is the present value of counter 46 and
R is the result word.
