DM Area Settings and Functions
Section 7-2
Range Enabled/Disabled
(Word (m+5) or (m+6))
These bits are used to enable or disable ranges 0 to 15. Bits 00 to 15 corre-
spond to ranges 0 to 15.
The settings will be valid when the High-speed Counter Unit is turned ON or
restarted until new ranges are transferred to the High-speed Counter Unit.
In the following example, ranges 0, 1, 4, and 15 are enabled.
Maximum Count Value
(Word (m+7) and (m+8)
Word (m+9) and (m+10))
These bits must be set in circular mode only.
Set these bits to the maximum count values of the counters.
For example, the count value changes as shown below if the maximum count
value of a counter is 9,999.
. . . 9997

9998

Upper and Lower Limits,
and Output Pattern
A maximum of 16 ranges can be set within a range of word m+15 for range 0
and word m+94 for range 15. Each range uses five words.
Example:Range 0 (BCD)
Lower and Upper Limits
Lower and upper limits must satisfy the following conditions, otherwise an
error will result when the High-speed Counter Unit is turned ON and the Unit
will not operate.
