4-4-5 Application Examples
Gate Mode: Measuring Product Length System Configuration
Counter Unit
C200H PC
Control Input IN1
Inputs A and B
Encoder
An encoder adapter
is required if the
C200H-CT002 is
used with an open-
collector encoder.
Product
Photoelectric switch for
detecting product
Encoder adapter
Operation This example system counts encoder inputs while the photoelectric switch is
ON to measure the lengths of products on a conveyor. The PC uses the re-
sulting length measurements to determine if product lengths are within stan-
dards.
Switch Settings In this example, the unit number selector is set to and 1 and the mode selec-
tor is set to 4.
All pins are turned OFF on the back panel DIP switch to designate offset phase
inputs with no input multiplier.
Wiring
1, 2, 3... 1. Connect encoder outputs to inputs A and B.
2. Connect the photoelectric switch output to control input IN1.
DM Area Settings
DM 1100 0 4 0 0
0 0 0 0 DM 1101
Sets the mode to 4 (gate).
Designates use of control IN1
from the connector (not the inter-
nal IN1) and normal gate mode
(not cumulative).
