Range- and Comparison data

Item
Data Range 00 – Data Range 31
Data Comparison Value 00 – Data Comparison
Value 31
Example:
The High-speed Counter Unit is assigned Machine Number 6. You want to change
the Maximum Count Value of Circular Counter 3. The new Maximum Count Limit
consists of 2 words, is located in Data-Memory at address D0050 and D0051 and
is equal to 2710 (=10,000 decimal).
H
IOWR(223)
#3C03 CC1= 3C (= Counter 3), CC2= 03
D0050 S= D0050 (first word with new Maximum Count Value)
#00020006 D= #0006 (Machine Number) and D+1= #0002 (# words)
Example:
The High-speed Counter Unit is in Range Mode and is assigned Machine Number
3. You want to read the Range Enable Data of Counter 2 and write it to D1800 in
the PLC memory.
IORD(222)
#2B03 CC1= 2B (= Counter 2), CC2= 03
#00020003 S= #0003 (Machine Number) and S+1= #0002 (# words)
D1800 D= D1800 (write Range Enable Data to D1800 and D1801)
The Unit can be in Range or Comparison Mode (refer to 3-5-1 "Range Mode" and
3-5-2 "Comparison Mode"). IOWR- and IORD-instructions can be used respec-
tively to change Range/Comparison Data inside the Unit or to read Range/Com-
parison Data from the Unit, during actual operation. Depending on the mode of the
Unit (Range or Comparison mode) the Control Code is interpreted accordingly by
the High-speed Counter Unit.
