1-3 System Configuration
Example Configuration The following example system configuration uses the Counter Unit to deter-
mine whether or not product length is acceptable. The length of the products
passing by on the conveyor is measured by using the output from a photo-
electric switch to initiate and end counting of pulses output from an encoder.
Product length is checked against standards and the product is ejected if it is
out of the acceptable range.

Many other applications are possible by combining other types of inputs and out-
puts. Refer to Section 4 Data Allocation and Operating Modes for other applica-
tion examples.
A maximum of 10 Special I/O Units, including Position Control Units, Counter
Units, etc., can be mounted under the same PC, regardless of whether they
are on the CPU Rack, the Expansion I/O Rack, or the rack containing a Re-
mote I/O Slave Unit controlled by the PC. No more than four of these can be
mounted onto any one rack containing a Remote I/O Slave Unit.
Mounting Location The Counter Unit can be mounted to any but the 2 rightmost CPU Rack slots.
Mounting the Counter Unit to either of these slots will prevent you from
mounting devices directly to the PC’s CPU.
The back panel DIP switch must be set before the Counter Unit is mounted.
(Refer to 2-1 Switch Settings.)
