Counter - Functions
•
Start the Siemens SIMATIC Manager with your project and open the
hardware configurator.
•
Place a profile rail.
•
Configure at slot 2 the corresponding CPU from Siemens CPU 31xC.
•
Open the dialog window "Properties" by a double click to the
Count
submodule of the CPU.
•
As soon as an operating mode to the corresponding channel is selected,
a dialog window for this operating mode is created and displayed and
filled with default parameters.
•
Execute the wished parameterization.
•
Store the project with
Station
>
Save and compile
.
•
Transfer the project to the CPU.
Via the parameterization you have the opportunity to define a main
counting direction for every counter. If "none" or "endless" is chosen, the
complete counting range is available:
Limit counter Valid value range
Lower count limit -2 147 483 648 (-2
31
)
Upper count limit +2 147 483 647 (2
31
-1)
Otherwise this range may be limited in both directions by a start value as
load value
and an
end value
.
Main counting direction forward
Upper restriction of the count range. The counter counts 0 res. load value
in positive direction until the parameterized end value –1 and jumps then
back to the load value with the next following encoder pulse.
Please note a load value may exclusively be set by the request interface of
the counter.
Main counting direction backwards
Lower restriction of the count range. The counter counts from the
parameterized start- res. load value in negative direction to the
parameterized end value +1 and jumps then back to the start value with the
next following encoder pulse.
Please note an end value may exclusively be set by the request interface
of the counter.
