Operation and Configuration
Every Counter of the High-speed Counter Unit can be set to Simple, Circular or Linear Counter
(refer to 1-5 Operating Procedure Guidelines for quick start up information).
One CJ1W-CT021 High-speed Counter Unit occupies dedicated areas for four Units. Therefore, the
maximum number of Units that can be mounted on all CPU Racks and Expansion Racks is 24.
As a Circular or Linear Counter, all functions of the Unit can be used. As a Simple Counter, how-
ever, available functions are restricted. The figure below shows all the function blocks that can be
set and used. The tables on Pages 1-14 and 1-15 explain the functions that can be used by a Circu-
lar or Linear Counter and by a Simple Counter.
* Diagram is valid for Counter 1 and 2.
