Configuration and Programming 4-13
The Range Starting Value specifies the start of the range and the Range
Ending Value specifies the end. While using the Ring Counter Type
and the Starting > Ending, the range extends across the rollover count
(Maximum Count Value). While using the Linear Counter Type and
the Starting > Ending, the range extends from Starting to 32767 and
from -32767 to Ending. Refer to the Range Mode with Linear Counter
example in Chapter 2.
Ranges may overlap. When within more than one range, the outputs
of those ranges are combined (logical OR).
M0:e.34 Maximum Count (Static) / Reset Value (Dynamic)
Maximum Count
When the module is configured as a Ring Counter type, this word
allows you to specify the ring rollover count. The range of this value
is 1 to +32767. If reset to 0, a configuration error occurs.
The example below specifies a rollover count of 32,767.
