Counter Mode
– Applies to WBK17 Only.
WaveView supports several counter modes and can receive input
from up to two encoders (in 1X, 2X, or 4X modes).
All WBK17 modes are detailed in the WBK17 Document Module.
Note: The Encoder Mode can only be selected on WBK17
channels x-1 and x-5. Inputs “B” and “Z” must be
connected to the next consecutive channels.

Reference Note:
Refer to the
WBK17 Document Module (in the WBK
Option Cards and Modules User’s Manual,
p/n 489-0902) for additional information regarding the
following counter modes.
•
Counter
The counter makes use of a 16-bit counter (Counter Low), or a 32-bit counter (Counter High). While
in this mode, the channel’s input increments the counter. The counter is cleared at the beginning of
each scan, and the value [just prior to clearing] is latched and returned to the WaveBook/516, /512A,
or WaveBook/516A. See the upcoming Programmer Note.
•
Totalize
The totalize mode makes use of a 16-bit counter (Counter Low), or a 32-bit counter (Counter High).
While in this mode, the channel’s input increments the counter and rolls it over, resulting in a
cumulative total for the counter value. (see the following Programmer Note)
Programmer Note:
In regard to programming, the “Counter Mode” involves selecting the “Clear on Read” option
within a single “Counter/Totalize Mode;” and the “Totalize Mode” involves selecting the
“Totalize” option. In WaveView, the Counter and Totalize modes are treated as two distinct
modes. Note that the “Clear on Read” mode is not available when using an external clock.
