Refer to 3-2-1 "Simple Counter" for more details about the Simple Counter.
All Counters as Circular or Linear Counter:
1. Every Counter can now be separately (DM-) configured. For this purpose you
can use a Programming Console or CX-Programmer Support Software. The
configuration of the Counter Type (Linear or Circular Counter) is done by DM-
setting. Refer to SECTION 3 "Operation and Configuration" for detailed infor-
mation about configuring the Unit.
2. Power up the PLC again or turn the Special I/O Unit Restart Bit to ON (to trans-
fer the DM-settings). All data related to Circular /Linear Counters is now being
exchanged between the PLC and the Unit in CIO-memory and available for
usage in the Ladder Program.
3. Create and RUN a Ladder Program in the PLC. Refer to SECTION 4 "Exchang-
ing Data with CPU" for details on the interface between the CJ-series High-
speed Counter Unit and the CPU. Refer to sections 6-2 to 6-5 for application
examples using Circular and Linear Counters.
Refer to 3-2-2 "Circular Counter" and 3-2-3 "Linear Counter" for more details
about both Counter Types. Refer to 4-1-2 "Special I/O Units Restart bits" for more
information about restarting the Unit.
Mixed Configuration Simple/Circular/Linear Counters:
1. Every Counter that has been set to Circular/Linear Counter can now be (DM-)
configured. For this purpose you can use a Programming Console or CX-Pro-
grammer Support Software. The configuration of the Counter Type (Linear or
Circular Counter) is done by DM-setting. Refer to SECTION 3 "Operation and
Configuration" for detailed information about configuring the Unit. For the
Counters that have been configured for Simple Counter no (DM-) configuration
has to be done since the default (=0000) DM-settings are used for these
Counters.
2. Power up the PLC again or turn the Special I/O Unit Restart Bit to ON (to trans-
fer the DM-settings). All data related to Circular/Linear Counters is now being
exchanged between the PLC and the Unit in CIO-memory and available for
usage in the PLC Ladder Program.
3. Create and RUN a Ladder Program in the PLC. Refer to SECTION 4 "Exchang-
ing Data with CPU" for details on the interface between the High-speed Counter
Unit and the CPU. Refer to sections 6-2 to 6-5 for application examples using
Circular and Linear Counters.
Refer to 3-2-1 "Simple Counter", 3-2-2 "Circular Counter" and 3-2-3 "Linear Coun-
ter" for more details about the Counter Types. Refer to 4-1-2 "Special I/O Units
Restart bits" for more information about restarting the Unit.
Note For using Simple Counters you do not have to clear the corresponding DM-set-
tings to zero (=0000), since the Unit does not use this information and always uses
the default (=0000) settings.
