Configuring each Counter starts with choosing the Counter Type, i.e. it must
be configured for Circular or Linear Counter (refer to section 3-2-1 Circular
Counter, section 3-2-2 Linear Counter and section 1-5 Operating Procedure
Guidelines for details).
Next, the Input Type (Phase Differential, Up/Down, or Pulse & Direction) for
every Counter has to be defined. During operation of the Counter, the Counter
can be Started, Stopped, Reset, Captured or Preset by using the corresponding
bits in CIO.
In order to link the Units Software Outputs to Counter events, the Output Con-
trol Mode (Range or Comparison Mode) must be selected. Furthermore, an
additional Hysteresis mechanism is available to control the Outputs. Refer to
section 3-5 Output Control.
The CJ1W-CTL41-E Counter Unit allocates 90 DM-words in the Special I/O
Unit DM-Area and a block of 34 CIO-words in the Special I/O Unit Area of the
PLC. The configuration of the Unit is done by making the appropriate DM-set-
tings in the Special I/O Unit DM-Area allocated to the Unit.
The Special I/O Unit DM-Area is divided in an area of 10 words to make the
General Unit Settings and 4 blocks of 20 DM-words each to make the Counter
Specific Settings, which are unique for every Counter.
