Counter Type Switch

!Caution
28
The Counter Type Switch, at the front of the Unit, is used to set the Counter Type
for every individual Counter separately. By default all Counters are set to Simple
Counter.
Default state
(all pins set to OFF)
ON OFF
Note: Pins are set to ON when they are raised at an angle.
The following table shows how the Counters can be configured:
Pin Counter Position
1 #1 ON
OFF
2 #2 ON
OFF
After having set the DIP switch of the Counter to ON, further selection between
Circular and Linear Counter, is done by DM-setting. Counters that are configured
for Circular/Linear Counter can make use of all the features that the High-speed
Counter Unit offers. More information on Circular and Linear Counters can be
found in 3-2-2 "Circular Counter" and 3-2-3 "Linear Counter" respectively.
The Simple Counter is an extra feature of the High-speed Counter Unit, that ena-
bles an easy and fast set-up of the Unit since no (DM-) configuration settings have
to be made (all default (=0000) DM-settings are used). Consequently for Simple
Counters only a reduced subset of all the features that the Unit offers are availa-
ble. For further details about the Simple Counter and the features supported, see
3-2-1 "Simple Counter".
Since the Counter Type Switch is located at the back of the Unit, always turn OFF
the power to the PLC before installing or removing the Unit.
Example: Pin 1 set to ON and
pin 2 set to OFF
ON OFF
