Basic Configuration
Mounting Restrictions
The CJ1W-CTL41-E Counter Unit is a Special I/O Unit belonging to the CJ
Series. A CJ1W-CTL41-E Counter Unit can be mounted to either a CJ CPU
Rack or CJ Expansion Rack.
Note
1.
In case of a CJ1-H CPU Unit, the Counter Unit must be in one of the five
positions immediately to the right of the CJ1-H CPU Unit on the CPU Rack,
in order to allow the CJ1W-CTL41-E Counter Unit to generate interrupts
which activate interrupt tasks in a CJ1-H CPU Unit.
2.
In case of a CJ1M CPU Unit, the Counter Unit must be in one of the three
positions immediately to the right of the CJ1M CPU Unit on the CPU Rack,
in order to allow the CJ1W-CTL41-E Counter Unit to generate interrupts
which activate interrupt tasks in a CJ1M CPU Unit
3.
No interrupt tasks can be activated in CJ1-H or CJ1M CPU Units if the
CJ1W-CTL41-E Counter Unit is in any other position (i.e., 6th Unit position
or further away from the CJ1-H CPU Unit, or 4th Unit position or further
away from the CJ1M CPU Unit), or if it is on a CJ-series Expansion Rack.
Maximum Number of
CJ1W-CTL41-E Units
The maximum number of CJ1W-CTL41-E Counter Units which can be
mounted to a CJ CPU Rack or CJ Expansion Rack is equal to the number of
slots of the Rack. In a configuration with multiple Racks the maximum number
of CJ1W-CTL41-E Counter Units is limited to 24.
Furthermore, the number of Counter Units that can be mounted to one Rack
(i.e., a CPU Rack or Expansion Rack) depends on the maximum supply cur-
rent from the Power Supply Unit that supplies the Rack and the current con-
sumption of other Units on the Rack.
