Counter Types
Every single Counter of the High-speed Counter Unit can be set independently to
one of the following Counter Types (for an overview of the differences between
Simple and Circular/Linear Counters refer to 1-4
•
Simple Counter (refer to section 3-2-1
•
Circular Counter (refer to section 3-2-2
•
Linear Counter (refer to section 3-2-3
The configuration starts by setting each Counter’s DIP switch at the back of the
Unit in the appropriate position. By default this switch is in the OFF position which
selects the Simple Counter. To select a Circular or Linear Counter set the switch
in the ON position. After you have set the DIP switch in the ON position you can
configure every Counter as Circular or Linear Counter by giving the corresponding
word in DM the appropriate setting:
For Circular and Linear Counters all the functions and features of the High-speed
Counter Unit are available and configurable. For Simple Counters only the default
functions and features are supported since the Unit ignores the DM-settings for
Simple Counters.
Counter Value
For all Counter Types the 32-bit Counter Value is reflected in CIO.
3-2-1
Simple Counter
The advantage of using a Counter as a Simple Counter is that you do not have to
make any DM-configuration settings. Instead, all default DM-settings are used. As
a consequence Simple Counters can only be used in a default configuration. If you
intend to use the High-speed Counter Unit only with Simple Counters the informa-
tion as described in this section “Simple Counter”, covers all the default features
and functions that are important and available to you.
