Performance Specifications of Counting Function
Refer to the following for the performance specifications of the counting func-
tion.

DM Area Settings and Functions
Values can be written to the DM area with ladder programs or the Program-
ming Console.
m = 1000 + 100 x Unit No. (0 to 15)
The values set in the DM area are transferred to the High-speed Counter Unit
when the High-speed Counter Unit is turned ON or restarted. Any set value
changed while the High-speed Counter Unit is in operation will be transferred
to the High-speed Counter Unit when it is turned on again or restarted.
Description
In this manual, the words and bits of counter 1 are described first followed by
the words and bits of counter 2.
In the following example, word m+1 and bit 01 are for counter 1 and word m+2
and bit 02 are for counter 2.
Example: Counter input type (Word (m+1) or (m+2) bits 03 to 00)
Counter reset (Word n bits 01 or 02)
Operating Mode
(Word m Bits 03 to 00)
Set these bits so that the setting will correspond to the MODE switch setting.
